<li>It&#8217;s unbelievable: I haven&#8217;t added a blog post in <em>nearly a year</em>. Worse, I have no excuse – writing is an activity I both enjoy and want to improve at; additionally, I&#8217;ve had a sufficiently interesting year to provide me with decent writing material.
</li>
<li>MediaTemple Grid Hosting is <strong>slow</strong>. Really, unforgivably slow. Really, I (i) opened Word, (ii) registered by blog account, and (iii) typed this before the <strong>Add New Post</strong> page finished loading. I realize I don&#8217;t get much traffic – 100 hits a month? – but that&#8217;s <em>unforgiveable</em>. Frankly I should move off them entirely for simple hosting like this, but I might shift to a (ve) server since migrating would be helluva lot easier.</li>

			<content:encoded><![CDATA[<p>In the past few weeks, there have been a number of stories presaging a shift in how Google and other search engines rank content. </p>
<p>The contention is simple enough: Current search engine technology is limited because people game the system. Lately, people have been gaming the system a bit too successful; people have documented the unreasonable success of both <a href="http://searchengineland.com/demand-medias-ipo-the-google-seo-aspects-48286">Demand Media</a> (recent IPO) and <a href="http://www.slate.com/id/2284188/">The Huffington Post</a> (just sold to AOL). </p>
<p>“Gaming the system” is, in the system, called “Search Engine Optimization.” And, &#8211; due to the recent scrutiny -&#160; a number of people are taking the opportunity to forecast the death of search engine optimization.</p>
<p><a href="http://www.slate.com/id/2284353/pagenum/all/">Farhad Manjoo makes the argument in Slate</a> that content farms are doomed an ignoble death. According to him, the problem is that “<em>Google&#8217;s weaknesses aren&#8217;t permanent.</em>” </p>
<p>There are a few problems with this forecast. To illustrate them, let me back up a bit and discuss search engines and content farms. </p>
<p>Originally, a search engine existed to answer the question “Which pages on the internet have to do with my query?” But, as their power and success has grown (and by “their” I mean “Google’s”) so has the scope of their ambition.</p>
<p>Now, a search engine exists to provide a (satisfactory) answer to a searcher. </p>
<p>The history of search engines means that this has taken the form of links (10 to a page!) and, occasionally, in-line answers (Bing’s “Instant Answers” and the like). The current form of search engine results as a set of blue links casts the search engine strictly as an intermediary between the <em>searcher</em> and the <em>answer. </em></p>
<p>The history of search engines also lead to the rise of content farms.</p>
<p>From an objective perspective, content farms fulfill the same goals as search engines. That is, a content farm aims to have a <em>page</em> ready for every <em>question</em> an individual may have. Whether it’s <a href="http://www.ehow.com/how_6040_train-hamster.html">How to Train My Hamster</a>, <a href="http://www.ehow.com/how_4874937_kill-flies-house-mushrooms.html">How to Kill Flies in Your House with Mushrooms</a>, or <a href="http://www.ehow.com/how_13677_set-super-bowl.html">How to Set Up a Super Bowl Party</a>, eHow has a page ready.</p>
<p>How do they know what pages people want? Well, it’s pretty simple: they mine search engine data. (Well, plus some guesswork and interpolation). </p>
<p>It’s a pretty ingenious idea: people are looking for things on Google, so why not create the very things they’re looking for? <em>You already know what they’re looking for</em>, since they’re <em>already searching.</em></p>
<p>Really, it’s a wonder search engines didn’t think of the idea themselves (<a href="http://www.mahalo.com/">Oh, wait, they did</a>).</p>
<p>Now, due to revenue concerns, most of the content in content farms is crap. You pay very little, and then reap in the advertising revenue. As the advertising revenue scales with how much traffic you get, and traffic comes almost exclusively from search engines, content farms sink a huge amount of effort trying to find (i) what search engines consider important, and (ii) doing more of what they consider important. </p>
<p>This is problematic for a few reasons, all of which can be summed up by: “Google isn’t perfect.” </p>
<p>More specifically, search engines like Google measure <em>proxies</em> of quality and use it as an indicator of quality. This is expressed most clearly in Google’s big breakthrough – PageRank. PageRank assumes that (i) humans link to web pages, and (ii) on average, a link is a vote. <em>Someone</em> considers the page valuable, or <em>no one would be linking to it</em>. Certainly, Google uses other variables (Bing uses over a thousand, so we can infer that Google uses <em>at least</em> that many. Sort of.). But (almost) all of them are proxies for value – proxies for the reality of the situation.</p>
<p>When content farms engage in search engine optimization, they are “tricking” Google into thinking that their content is higher quality that it actually is. </p>
<p>To an extent, this is purely a trick. Google must – and has in the past – responded by de-valuing signals which people being to manipulate consciously. </p>
<p>But in another sense, this is good: some of the things Google tracks actually <em>do</em> have to do with quality. The announcement last year that Google was going to begin using page load speed as a ranking factor is an example – sites that load faster as more pleasant to use, so sites that work for a higher Google ranking will also benefit site users.</p>
<p>In that sense, search engine optimization is similar to grammar. Yes, a writer with poor grammar <em>can</em> communicate himself – but it’s considerably easier for a reader to interpret someone who has a grasp of good grammar.</p>
<p>This explanation of search engines and content farm&#160; suggests a couple of things. </p>
<p>First, that search engine optimization isn’t going anywhere (nor has grammar, to the dismay of many).</p>
<p>Second, that as Google becomes better at providing links to high quality answers, content farms will provide higher-quality answers. </p>
<p>It’s a terribly symbiotic relationship. Since content farms subsist on advertising revenue, the more accurately Google (and others) can reflect user judgment, the higher the quality of the content that content farms will produce. </p>
<p>Unless both run out of money, which is rather unlikely – after all, it’s Google (AdSense) that’s paying the bills for the content farms, and it’s Google AdWords which is paying the bills for search. </p>

			<content:encoded><![CDATA[<p>In 2006, HBR Ideacast (in its fourth podcast) interviewed HBR Senior Editor Gardiner Morse on an article he&#8217;d working on – concerning so-called &#8220;deliberate mistakes.&#8221;
</p>
<p>I found the podcast very interesting – primarily because the idea it explored was something I&#8217;d covered extensively in my major.
</p>
<p>Let me back up: Mr. Morse explains how over the past couple of decades businesses have embraced &#8220;experiments&#8221; to test if things will work. However, simply running experiments isn&#8217;t enough – a business also has to make &#8220;deliberate mistakes,&#8221; which reduces to running experiments <strong>you believe will fail</strong>. A problem with running experiments that <em>confirm</em> your experiments is that you become trapped by your assumptions – and you may end up &#8220;assuming&#8221; things that can cost your company millions of dollars.
</p>
<h3>AT&amp;T<br />
</h3>
<p>The example that Paul Schoemaker and Robert Gunther begin their article with is AT&amp;T:
</p>
<blockquote><p>Before the breakup of AT&amp;T&#8217;s Bell System, U.S. telephone companies were required to offer service to every household in their regions, no matter how creditworthy. Throughout the United States, there were about 12 million new subscribers each year, with <strong>bad debts exceeding $450 million annually</strong>. To protect themselves against this credit risk and against equipment theft and abuse by customers, the companies were permitted by law to demand a security deposit from a small percentage of subscribers. Each Bell operating company developed its own complex statistical model for figuring out which customers posed the greatest risk and should therefore be charged a deposit. But the companies never really knew whether the models were right. They decided that the way to test them was to make a deliberate, multimillion-dollar mistake.
</p>
</blockquote>
<blockquote><p>For almost a year, the companies asked for no deposit from nearly 100,000 new customers who were randomly selected from among those considered high risks. […] To the companies&#8217; surprise, many of the presumed bad customers paid their bills fully and on time and did not steal or damage the phones. Armed with these new insights, Bell Labs helped the operating companies recalibrate their credit scoring models and institute a much smarter screening strategy, which <strong>added, on average, $137 million to the Bell System&#8217;s bottom line</strong> every year for the next decade. (emphasis added)
</p>
</blockquote>
<p><a href="http://hbr.org/2006/06/the-wisdom-of-deliberate-mistakes/ar/1">Continue article here</a>.
</p>
<p>Now, before you ask specific – why couldn&#8217;t AT&amp;T retroactively identify these people; why wasn&#8217;t this data used in the creation of the formula (as opposed to credit score, income, neighborhood, etc; which Mr. Morse implied they used); why did they have to exclude people from the insurance plan to learn this? – the podcast didn&#8217;t going into that. Being the generous guy I am, I&#8217;m going to assume a &#8220;displacement of responsibility&#8221; effect – that is, charging the insurance fee eliminated the social obligation to not damage the equipment, thus charging the fee actually <em>increased</em> damaged equipment. It&#8217;s quite plausible, and fits the narrative better.
</p>
<h3>Enter Science<br />
</h3>
<p>The state of experimentation in business is baldly stated:
</p>
<blockquote><p>Many managers recognize the value of experimentation, but they usually design experiments to confirm their initial assumptions.
</p>
</blockquote>
<p><strong>This is where science was in the 1920s</strong>.
</p>
<p>In the 1920s, the <a href="http://en.wikipedia.org/wiki/Vienna_Circle">Vienna Circle</a> was in full swing – refining and popularizing the philosophical doctrine of <a href="http://en.wikipedia.org/wiki/Logical_positivism">Logical Positivism</a>, which quickly permeated science. The fundamental tenet of logical positivism is that everything can be derived from empirical data (e.g. experiments) and logical inference. It&#8217;s a rejection of both theology and metaphysics – &#8220;postulating&#8221; (or assuming) that reality works in a certain fashion without any direct evidence.
</p>
<p>In the 1930s, <a href="http://en.wikipedia.org/wiki/Karl_Popper">Karl Popper</a> popularized <a href="http://en.wikipedia.org/wiki/Falsifiability"><strong>falsification</strong></a><strong>. </strong>Falsification is a logical correction – it points that the &#8220;<a href="http://en.wikipedia.org/wiki/Problem_of_induction">problem of induction</a>&#8221; popularized by David Hume in 1748 means that it&#8217;s impossible to arrive at &#8220;true&#8221; knowledge by induction (going from evidence to theory). This is the &#8220;all swans are white&#8221; fallacy that Nicholas Taleb used to great effect in his book <em>The Black Swan</em>: no matter how many white swans you see, it doesn&#8217;t mean a black swan doesn&#8217;t exist. The logically <em>valid</em> way to proceed is to create a theory, then derive a hypothesis, then to <em>test</em> that hypothesis against the evidence. You only need <em>one</em> disconfirming example (e.g. a single black swan) to disprove the hypothesis; so by falsifying hypothesis you can have a &#8220;process of elimination&#8221; of hypotheses and theory.
</p>
<p>Now, it turns out that (philosophically) there are a few problems with that way of progressing, one of which is known as the <a href="http://en.wikipedia.org/wiki/Duhem%E2%80%93Quine_thesis">Duhem-Quine thesis</a> (Quine has a nice, if overstated, explanation in <a href="http://www.ditext.com/quine/quine.html"><em>Two Dogmas of Empiricism</em></a><em> – </em>he later partially retracted his conclusion). In short, it states that hypothesis cannot be isolated and tested individually – rather, you are testing a bundle of interconnected theses, which makes it very difficult to falsify <em>any</em> hypothesis. Another problem is <a href="http://en.wikipedia.org/wiki/Underdetermination">underdetermination</a>, which claims that that there are <em>n</em> possible (contradicting) theories for any finite amount of evidence, where <em>n</em> &gt; 1 (and usually very large). Thus, (practically speaking) a company can have any amount of evidence and have multiple contradicting theories available – making it very difficult to choose which action to take where the theories contradict.
</p>
<p>(On the bright side, the theories are going to overlap a lot, too – they need to agree on the empirical evidence, after all – so the more evidence you have, the better off you&#8217;ll be. It&#8217;s just not <em>certain</em>).
</p>
<h3>Practical Reasons<br />
</h3>
<p>However, these problems are of little <em>practical </em>significance in business, where the goal is not to be &#8220;right&#8221; but to be &#8220;more correct then the next guy&#8221; – your competitors. Business is a <em>relative</em> thing, so <em>relative</em> increases in truth have real business value.
</p>
<p>In fact, there is a <em>more compelling</em> rationale to use falsification in business than there is in science.
</p>
<p>&#8220;Savvy executives&#8221; – to borrow HBR&#8217;s favorite phrase – are considerably more vulnerable than scientists to cognitive &#8220;traps&#8221; that psychologists have identified. Why? Because whereas pressure is on scientists to produce <em>truth</em>, executives are under pressure to <em>make it work</em>. And boy oh boy, is the <a href="http://en.wikipedia.org/wiki/List_of_cognitive_biases">list of cognitive biases a mile long</a>. The most significant cognitive errors for executives are:
</p>
<ol>
<li><strong>Confirmation Bias</strong>: When someone considers a hypothesis or opinion, they reach back in their memory for instances that <em>confirm</em> the hypothesis – and <em>suppress</em> recollection of instances which <strong>disprove</strong> the hypothesis.
</li>
<li><strong>Regression to the Mean</strong>: People tend to ignore probabilities, and focus on the most recent event. In probability, an <em>exceptional</em> event – e.g. very good (or very bad) returns – is likely to be followed by a <em>more ordinary</em> event. The classic example is for a flight instructor who swore that negative feedback works (it doesn&#8217;t) – his explanation was that every time a pilot did exceptionally badly and he yelled at them, they did better the next time. This was true – but after an exceptionally bad landing, a pilot is likely to <em>regress to the mean</em> (of his capabilities) and therefore do better. This also applies to, e.g. stock trading and revenue/sales performance (this is part of the reason why it&#8217;s <em>very bad</em> to base firing/compensation on just the last year of results).
</li>
<li><strong>Hindsight Bias</strong>: The tendency to look at a previous event and believe that <em>you saw it coming</em> – and didn&#8217;t – but that gives you confidence in predicting future events.
</li>
<li><strong>Overconfidence effect</strong>: For many questions, answers that people rate as being &#8220;99% certain&#8221; are wrong 40% of the time.
</li>
<li><strong>Halo Effect</strong>: Judgment about one attribute spills over to other attributes… e.g. Google is doing really well, therefore <em>everything they do</em> is really good as well; or, people who are more attractive are better at their work.
</li>
</ol>
<p>There are – quite literally – hundreds more; but let me explain what these combine to in terms of falsification.
</p>
<p>Obviously, confirmation bias, hindsight bias, and the overconfidence effect combine to make people <em>very bad</em> at predicting what&#8217;s going to happen next. Together, they mean that (i) people believe they&#8217;re good at understanding or forecasting the situation, and (ii) only remember information which conforms to their opinions.
</p>
<p>The halo effect means that people will routinely <em>focus on the wrong things</em> – that is, they will take an indication of one thing as an indication of another, unrelated, thing. AT&amp;T is an example – they <em>assumed</em> that credit risk indicated bad debt and equipment theft/damage – when it did not.
</p>
<p>And &#8220;regression to the mean&#8221; means that people are likely to base their predictions on <em>exceptions</em> as opposed to the underlying reality – essentially, to <strong>overestimate the amount of control they can exert on the situation</strong>. (Incidentally, the &#8220;fundamental attribution error&#8221; – the tendency to ascribe people&#8217;s performance to their <em>nature</em> as opposed to their <em>situation</em> – is not unrelated).
</p>
<p>The combination of (i) focusing on the wrong thing, (ii) being overconfident of their understanding, (iii) not questioning their opinions, and (iv)  overestimating the amount of control they can exert is <em>not</em> a good combination.
</p>
<p>The practice of <em>falsifying</em> hypothesis is good in two ways: first, it&#8217;s humbling to realize when you&#8217;re wrong. Second, it provides basic ammunition to hobble people&#8217;s initial false conclusions.
</p>
<p>The twin benefit of providing both discipline and improved performance – is, well, quite compelling.
</p>
<h3>Inheriting Methodology<br />
</h3>
<p>The interesting fact is that it seems that business is, slowly, picking up the methodology of science.
</p>
<p>In some ways, business has had scientific ideas introduced backwards. Consider the idea of a &#8220;paradigm shift,&#8221; which entered the business lexicon in the 1990s (and was promptly over-used); Kuhn introduced paradigm shifts in science in 1962, nearly thirty years after Karl Popper spoke of falsification. Experimentation has gained considerable traction in the past decade, closely followed by &#8220;deliberate mistakes&#8221; as Popperian falsification followed the Vienna Circle.
</p>
<p>The advance of scientific methodology is not limited to philosophical ideas – in 2009, for example, IBM acquired <a href="http://www.spss.com/">SPSS</a> (Statistical Package for the Social Sciences), and is now selling it as a Business Intelligence tool. Wall St is famous for hiring statistics PhDs to mine stock data; Google has become well-known for hiring newly-minted PhDs and giving them room to find the <em>best</em> solution to a problem (as opposed to a &#8220;sufficient&#8221; solution – or the first one that works).
</p>
<p>As business faces increasing competition, making sure you&#8217;re doing the right thing matters more and more – room for mistakes, or acting sub-optimally, is quickly disappearing in the modern, distributed, global marketplace. It will be interesting to see how business continues to adopt scientific methodologies to try and reduce the possibility of error (particularly recurrent, expensive error) in the future.</p>

<p>I find the above quote, <a href="http://ebranding.me/archive/strive-for-skills-not-a-degree/">from Rachel Esterline</a>, horrifying. </p>
<p>The conclusion that a college degree does not get you a job begs the question of what, precisely, a college degree <em>does</em> get you. There are rosy platitudes about “learning,” or “experiencing life” (really, just living out from under the ready hand of one’s parents for the first time). There are also depressing prognostications claiming that the purpose of college is to indebt Americans so that they are forced to enter the business world to pay off their debt. Indentured servants.</p>
<p>But let’s ignore that for now. </p>
<blockquote><p>In order to be a marketable job candidate once you graduate, I believe you need to spend hours outside of the classroom to develop your real-world skills</p>
</blockquote>
<p>College does not prepare you to get a job; well, then, what does? The author lists a number of things; it reduces to internships (experience), networking, attitude, and skills. </p>
<blockquote><p>You don’t necessarily need a degree to get a job. You need skills.</p>
</blockquote>
<p>Yes, skills. What are skills? “How to use Twitter” or “How to create a PivotTable in Excel?” Or are skills more along the lines of “How to write persuasively,” or “How to think clearly?” </p>
<p>It’s certainly difficult to say, and depends to no little extent on the job you’re pursuing. If you’re trying to get a job as a programmer, experience programming helps – but so does a solid knowledge of theoretical computer science, which you learn in college. And I imagine it’s quite necessary to have an Engineering degree to get a job as an Engineer.</p>
<p>A degree can act as a certification that you <em>have</em> certain skills. You can’t graduate from an Engineering program without a certain <em>minimum baseline</em> of both skills and knowledge.</p>
<p>But let’s step back and look at college a bit more. Broadly speaking, there are two types of college education: the liberal arts, and vocational studies. Vocational studies include Engineering and Welding, but I’d also through pre-professional programs like Social Work, Art, Theatre, and Business in there. </p>
<p>Liberal arts programs attempt to expose students to a broad array of concepts, methodologies, and techniques to build clear thinking and writing skills. This is necessarily ambiguous, and the results are rather difficult to quantify. As such, its benefits are questionable (and are frequently questioned).</p>
<p>Vocational programs attempt to distill the essential knowledge of a field, and provide that to a student. A Business major entering the workforce will know quite a bit more about how business works than someone lacking that education; he/she will understand marketing, finance, operations, business law, strategy, etc. Certainly, their knowledge will be broad (no one’s going to hire a new grad to spearpoint the development of a business strategy) but it will be a good overview of the field of business. That is, they’re unlikely to be tripped up by not understanding a major area of business – such as possible legal impediments when introducing a new product, or exporting a product overseas. </p>
<p>Naturally, we can expect liberal arts students to have difficulty quantifying what they learned, and how that’s beneficial to business (though you’d hope that the nature of the education would give them a clue of where to begin). However, it’s more troubling of students in vocational and pre-professional programs, where one would expect to feel confident in their understanding, and their ability to contribute to the bottom line.</p>
<p>There’s a possible explanation. College is taught by academics, who are trying to make more academics. To the extent that academia is separate from the concerns of business, people taught by academics won’t understand business concerns. For instance, if Professors in the Business department are interested in understanding how business works, they may neglect teaching the <em>skills</em> to be successful in favor of the <em>understanding</em> of what makes something successful. So a student could be quite good at evaluating whether or not something is going to work, but quite bad at making it work in the first place.</p>
<p>College could teach <em>general theory</em> without teaching <em>applicable skills</em>. The idea, of course, is that the skills necessary both change frequently, and there’s a huge selection of skills that people employ. Attempting to cover them all has a very poor return on investment. However, the theory of how something works gives students the ability to <strong>acquire the skills faster</strong> than they would otherwise be able to. A college degree may not certify that you have the skills required – but it could certify that you’re eminently capable of learning the skills in short order.</p>
<p>It would thus make sense that new graduates, upon entering the workforce, feel that nothing they learned is directly applicable to what they’re doing. It’s probably quite galling to spend four years of your life studying something, and then come out the other end faced with the task of learning a bunch more; vocational students especially, who may expect their education to deal with their jobs.</p>
<h3>Does College Get You a Job?</h3>
<p>The problem, of course, is that the author does not credit college with getting her a job – <em>at all</em>. This is obviously false on one level (<a href="http://www.bargaineering.com/articles/recession-college-graduates.html">the unemployment rate for college graduates is less then half that of the overall unemployment rate</a>), but that’s not sufficient to dismiss her claims. </p>
<p>The author could mean a few things. First, she could be claiming that college does not improve your chances of getting a job – rather, that the “real-world” skills you build during the time you’re coincidentally at college get you a job. It’s not sufficient to point to either the unemployment rate of college graduates to dismiss this; it’s possible that people who are more skilled (or more likely to acquire skills) go to college, and that college adds nothing.</p>
<p>Second, she could be claiming that skills improve your chances of getting a job. This is non-controversial: the more skills you have, the more ways people can use you, the more companies can consider hiring you, the more likely you are to be hired. It’s a simple numbers game. And, in a competitive economy, having additional skills can put you ahead of your classmates.</p>
<p>Third, she could be claiming that a college degree is necessary <em>but not sufficient</em> to get a job. That is: companies will not hire you without a college degree, or without a college degree <em>and</em> skills. You need both a degree <em>and</em> skills to get a job (while this possibility is rather undermined by her claim that “you don’t necessarily need a degree to get a job,” different jobs may have different standards; so no one will hire you without skills, some will hire you with skills, and more will hire you with a degree and skills). This option seems to impose a considerably amount of structure on the labor market – more, perhaps, than is warranted. Relaxing the structure reduces this option to a variation of the second, where both skills and degrees factor into your desirability (and/or flexibility) in the labor market.</p>
<p>Still, the first option is, in many ways, the most disturbing. The claim that what you learn in the classroom is unrelated to getting hired means that the benefit of attending college is learning the <em>other</em> skills: the “real-world” ones outside the classroom. Such an option begs the question of why attend college in the first place; there are surely cheaper ways to obtain those same “real-world” skills with paying tuition, which can be as high as $30k/year. Given how much time students spend attending and studying for classes, it’d probably be a lot faster as well. </p>
<p>Let’s assume this is true. Can we reconcile this depiction of college with my above musings? Well, one option is to shift the playing field, by claiming that a college education shows dividends later on in life. Perhaps, after you’ve had a few jobs, your education allows you to make fewer mistakes or somesuch. It’s not unreasonable to suppose that an entry-level position requires less than four years of training you received at college; they may be requiring something else altogether.</p>
<p>However, that’s dissatisfying. It simply shifts the value of college to later in life – and if that was true, we would expect to see <em>more</em> people attending college after they’ve worked for a few years. Instead, most people in college come directly from high school. </p>
<p>I prefer to believe that there is some additional value in college that the author is not considering. The question is how to define it, and where we can expect it to manifest. Unfortunately, that’s not something I’m well-equipped to answer…</p>

			<content:encoded><![CDATA[<p>Game Theory begs to be applied to the scenario described in a Knowledge@Wharton article “<a href="http://knowledge.wharton.upenn.edu/article.cfm?articleid=2575">A Seasonal Sale Shift</a>.”</p>
<p>The fourth paragraph opens like this:</p>
<blockquote><p>With retailers pushing sales earlier and earlier and consumers waiting later and later to buy, Baker Retailing Initiative managing director Erin Armendinger compares the situation to the children&#8217;s game of chicken.</p>
</blockquote>
<p>Chicken is, as we all know, a special application of the classic Prisoner’s Dilemma game – where the mutually agreeable situation is unstable, because both sides benefit from departing from it (as long as the other does not). </p>
<p>Not to mention the massive coordination failure between competing retailers: if a competitor starts offering markdowns, you have to as well or you’re screwed. Oh, the Betrand model, how easily you screw over retailers.</p>
<p>It’s a situation that begs for a game-theoretic analysis, but the article doesn’t even mention the phrase. </p>
<p>Also, they misuse the term “value proposition.” They’re conflating the idea of “value” (dropped wholesale by the profession of economics because it was too hard to pin down). The <a href="http://www.dpvgroup.com/articles/dpv-whitepaper/">value proposition encapsulates the experience the customer has due to your product</a> – rather similar to the famous Drucker quote “the world wants <em>holes</em>, not drill bits.” Price is always an aspect – especially in retail – but it’s not really related to the value proposition as such.</p>
<p>Now, retailers actually <strong>are</strong> changing their value proposition. From the article:</p>
<blockquote><p>For example, apparel retailers have been changing their supply chains and inventory as part of what&#8217;s known as a &quot;wear now&quot; strategy. While in the past, suggests Armendinger, retailers rolled out merchandise for a new season on a particular day &#8212; changing to displays of sweaters and corduroy pants in the height of summer&#8217;s heat &#8212; many are now offering a balance of clothing so people shopping in August can still find shorts and short-sleeved shirts.</p>
</blockquote>
<p>Funny how that works.</p>

			<content:encoded><![CDATA[<p><a href="mailto:Knowledge@Wharton">Knowledge@Wharton</a> recently featured an article explaining why ranking employees relative to their peers can backfire.</p>
<p>The astonishing thing is how rapidly people have forgotten two millennia of leadership.</p>
<p>The “astonishing” finding in the article – that&#160; is, astonishing to people who have managed to avoid 40 years of work in employee motivation by psychologists – is that (i) giving employees feedback comparing them to their peers can cause resentment, and (ii) financial rewards do not always correlate with higher attainment.</p>
<p>To look at the the issue another way: why was this astonishing? What’s necessary to believe <em>such</em> <em>that</em> people believed that doing those two things would actually improve employee productivity?</p>
<p>Simple: that people (employees) are highly rational actors knowingly engaged in competition with their peers for a finite amount of resources (compensation) who attempt to optimize their personal income with no regard to others.</p>
<p>That doesn’t sound terribly human – or terribly friendly, for that matter – so why did people act as if it were true? </p>
<p>Such is the influence of economics, the magical discipline which is two parts mathematical rigor and one part magical thinking (which directs the other two parts).</p>
<p>For purely practical reasons, early economists constructed <strike>models</strike> explanations of the economy that assumed that actors were perfectly rational. It was sort of a mind game: What would the perfect economy look like? To what extent is our current economy perfect?</p>
<p>It was a practical attempt because data simply wasn’t available to run empirical studies on something like the macroeconomy, or even large markets. The computational power simply wasn’t available to create sophisticated models using that could account for non-rational behavior. </p>
<p>Why? Because economists needed – that is, they weren’t capable of developing anything else – a model that was <strong>deterministic</strong>. An individual, placed in the same situation, would make the same decisions (assuming their situation has not changed). A non-deterministic model is both far more difficult to create, requires far more computation, and is also considerably less useful.</p>
<p>The second reasons is simpler – economists weren’t trying to predict what an individual would do, they were trying to predict what <em>all</em> individuals would do. That is, they assumed that the <strong>average of all actions in a market would be rational</strong>. And they found a reasonable amount of evidence supporting that, where they expected to (in markets that had other assumptions of competition).</p>
<p>This explanation is vastly oversimplified and ignores both some thinkers and some developments. </p>
<p>In any event, like all academia, a popular idea remains a popular idea – until the tides of reality can o’ercome it. The rationalism of individuals was repeatedly challenged (frequently by economists), but economists could successfully point out that they were talking to the average of all actions, so as long as the average turned out to be roughly rational, they were OK. Since economists never drifted down to individuals, everything worked out dandy.</p>
<p>The problem came when people – and I’m looking at business – who <em>did</em> deal with individuals attempted to apply the lessons of economics to running their business. After all, economics began as a normative science to figure out what <em>to</em> do – so applying those normative guidelines should lead to greater efficiency.</p>
<p>Except that the average of all actions is not the same as the average action. It’s the same as the myth of the perfectly normal man – he doesn’t exist. It’s a statistical accident, really, that arises when you take a distribution and reduce it to a single number.</p>
<p>Rationalism for individuals had all the advantages for business (HR and all) that it had for economists: it allows for a (mostly) deterministic system. Given a scenario, the rational person will make the rational choice. No more fuzzy-duddy special exceptions for snowflake-special individuals: just cold, hard, unfeeling, highly efficient rules.</p>
<p>And thus died the two-millennia history of leadership rooted in the idea of inspiration; or making people fight for a cause greater than themselves, producing something that stretched beyond their own narrow lives. </p>
<p>The death of the dream to change the world – replaced, as it were, by a mission statement to align interests. Oh, and a vision statement so you know where you’re going, allowing you to plan how best to get there.</p>
<p>On a completely unrelated note, the study the Knowledge@Wharton article references is completely inapplicable to the real world. It is, however, backed by a mountain of empirical and theoretical psychology.</p>

			<content:encoded><![CDATA[<p>The Republican party seems to be pushing the perennial myth that the “Free Market” will make the healthcare system more efficient. This ignores a wealth of evidence by respected neoclassical economists (such as Kenneth Arrow), but also ignores plain Micro 101.</p>
<p>To clarify, a few things are needed for a efficient market:</p>
<ol>
<li>Consumers have an indifference curve for consumption.</li>
<li>Suppliers are price-takers; they do not discriminate on price.</li>
<li>Consumers have full information about all products on the market.</li>
<li>There are no transaction costs and no barriers to entry/exit.</li>
<li>Homogenous products.</li>
<li>Constant returns to scale.</li>
</ol>
<p>It’s possible to quibble with one or two (you can argue that one is redundant, and others add more requirements, etc) but that’s the general necessary assumptions.</p>
<p>Now, the free market only exerts its magic is <strong>all requirements are fulfilled</strong>. Obviously, it’s not a binary result, so if you violate an assumption to a greater or lesser degree, the market becomes less efficient – and thus less “magical.” </p>
<p>This is not controversial. I just want to repeat: this is taught in every Micro 101 post, and freely acknowledged by every neoclassical economist.</p>
<p>Let’s consider the healthcare market.</p>
<p>First of all, consumers do not have set indifference curves for healthcare consumption. Certainly, there are exceptions; and there are some healthcare providers where people do have such indifference curves (non-essential providers).</p>
<p>However, the important stuff is the <strong>unpredictable</strong> stuff. It’s worth nothing that medical expenses are <a href="http://factcheck.org/2008/12/health-care-bill-bankruptcies/">involved in about half of bankruptcies</a>.</p>
<p>But from a logical standpoint, suddenly discovering cancer changes your desire to consume healthcare. <strong>This is not by choice</strong>. It’s in response to changing events.</p>
<p>As a consequence, forcing everyone to pay out of pocket for medical expenses (taking it to the extreme) would do nothing but forced people who have unfortunate medical problems to suffer and die – through <strong>no fault of their own, </strong>and outside of their ability to control.</p>
<p>This is the “moral issue” that Kenneth Arrow pointed out: do we, as a society, want to let citizens of our democracy sicken and die simply because they have the bad luck to fall ill?</p>
<p>Not to mention the related issues – healthcare is not homogenous (every person requires different treatment), suppliers are not price-takers, consumers never have full information on treatment options and costs, and there are tremendous transaction costs to undergo a procedure.</p>
<p>Any of those would be enough to kill the possibility of an efficient healthcare market.</p>
<p>But the deeper problem is assuming that people can ration their healthcare consumption, according to how healthy they want to be, and that costs for each person will be roughly equivalent (varying only in the <strong>amount they choose </strong>to consume). </p>
<p>That’s a fantasy, and a piss poor one at that.</p>
<p>Of course, healthcare has a number of problems currently – one of the major ones it the lack of decent incentives. How many people die in hospitals for lack of basic hygiene? For medical mistakes, like hooking up a feeding tube to a blood vein? And how is it that a hospital that tries to reduce medical accidents actually ends up <em>losing money</em> – because the real profit is in treating more serious disorders, so it pays to make someone sicker before you make them better?</p>
<p>Those problems can be solved either through incentive alteration (changing the entire pay system of health insurance) or through regulation; for obvious reasons, changing and enforcing regulation is the easier (politically feasible, economically feasible, and successful) way to fix or at least alleviate those problems. </p>
<p>Making healthcare more of a free market will not.</p>
<p>However much people talk of “moral hazard” and “tort reform.”</p>

			<content:encoded><![CDATA[<p>Computerworld has an article about <a href="http://www.computerworld.com/s/article/350918/20_20_Vision?taxonomyId=56&amp;pageNumber=2">what (IT) jobs will be like in 2020</a>. Ignoring the parent difficulty of forecasting a decade in the future, allow me to poke a few holes in their account.</p>
<p>There are two broad themes: first, that technology is changing the business landscape, driving more towards cloud-based and mobile solutions. </p>
<p>Second, that people in all categories lack the skills to react appropriately. I’m not going to dwell too long on the stereotyping – it’s pretty basic, such as claiming that there’s “gap between college and real-world experience” (surprise), that Gen-Xers have too much entitlement, that mid-career workers lack experience with technology, etc.</p>
<p>There are two issues with this pretty picture. First, it’s so damn broad that it could apply to anyone at any time; second, it over-emphasizes the impact of technology on business.</p>
<p>I know, I know: it’s a terrible surprise from a rag called “Computerworld.”</p>
<p>Business is about two things: money and relationships. While such a simplification is broadly inaccurate, it’s sufficient when talking about technology. The goals for technology are to lower cost, speed up existing processes, move into new areas, and make it easier to connect.</p>
<p>For all that people claim that Facebook, Twitter, LinkedIn, Salesforce, whateverothercompany is changing the way business works – well, they’re full of shit. Facebook makes maintaining existing social relations easier (no more writing letters/emails to update people), LinkedIn does the same for business networking, Twitter (and its cousin, blogs) make publishing your thoughts easier, and Salesforce (along with other automation technology) makes existing tasks easier.</p>
<p>You could say that the purpose of technology is to eliminate drudgery. </p>
<p>Now, it’s very true that people who make a living off of performing drudgery are challenged by this tendency. And it’s true that people who put up with drudgery to accomplish their real goal (like a salesperson who fills out paperwork so that they can sell) don’t like having processes changed on them. </p>
<p>But it isn’t true that the “skills” are changing so much. People who sell still need to sell; people who manage need to manage, etc. The communication channels change somewhat, but neither the goal nor the method undergo distinct changes.</p>
<p>Tools are just tools: they exist to make you more effective. If new technology makes you less productive – well, it’s not a very good tool then, is it? So why the hell are you adopting it?</p>

<p>In 1971 Edward de Bono published <a href="http://www.amazon.com/Practical-Thinking-Right-Wrong-Understand/dp/0140137831/ref=sr_1_1?ie=UTF8&amp;s=books&amp;qid=1277921424&amp;sr=8-1">Practical Thinking</a>, and has revised it multiple times; the last time in 1992.</p>
<p>It’s a charming little book, largely because – despite making some false statements – his advice is excellent, practical, and should improve thinking for almost anyone who reads (and applies) it. </p>
<p>The most interesting parts of the book, to me – given I have just completed a major in <em>epistemology</em>, or the study of knowledge (sort-of “how to think”) – was the advice about certainty. It’s well-known (now) that the feeling of certainty people sometimes have is bonkers. de Bono breaks down why it’s bonkers; but also provides ways of avoiding the issue.</p>
<p>I’m not going to re-hash his book, in part because he provides an excellent summary at the back of the book you can reference (and, really, it’s $4).    </p>
<p>But the most important takeaway for managers and other “practical thinkers” is the de Bono’s discussion on the tyranny of the YES/NO system. It’s a simple insight: If you keep saying “No” to new ideas, the idea you end up with will be the <strong>first</strong> idea whose answer <em>isn’t</em> “No.” That is, it <strong>will not be the best idea</strong>; it will be the first mediocre idea. Abandoning the “YES/NO” system of brainstorming is really rather important. </p>
<p>If you’ve studied, oh, logic, Quine, cognitive psychology, and the philosophy of science, all this stuff will be old hat (and some of it wrong). If not,&#160; I highly recommend it. </p>

<p>Today, I read <a href="http://www.amazon.com/Science-Fear-Shouldnt-Ourselves-Greater/dp/B001U0OGAY/ref=tmm_hrd_title_0">The Science of Fear</a> (2008) by <a href="http://www.dangardner.ca/">Daniel Gardner</a>. It’s a remarkably well-done book for what it is – namely, a journalist’s (informed) overview of some of the psychological components of fear, and a large number of example as to how people exploit that tendency to fear.</p>
<p>It’s a nice book because he relies on rather well-accepted psychological research, while going into great depth on examples. It helps people to understand that these principles actually mean something.</p>
<p>On the other hand, for those people who were looking for a explanation about how fear works inside the brain – such as myself – it’s a bit lacking. And the reliance on solid psychological principles means I didn’t learn any new psychology. Regardless, I enjoyed the read because it was well-written and interesting.</p>
<p>In lieu of a review, allow me to review some of his points. In the course of the book, Mr. Gardner outlined three ways the brain screws up, leading people to irrational fears. </p>
<h3>1. The Availability Heuristic</h3>
<p>The availability heuristic is a pretty good rule. It’s a general cognitive bias – pretty robust across all humans – and works out to people predicting the probability of events in proportion to how many instances of it they can recall (are available).</p>
<p>If you do something a lot – work on computers, go hunting, etc – then over time you establish a battery of experiences. If someone asked you how probable something was, you could reach back into your experience and get a feel for how many times you’ve seen it – and give a pretty good example. </p>
<p>The big advantage is that it’s computationally very fast. If you need to make a split-second decision, you want it to be fast.</p>
<p>It’s also extensible: that is, people don’t differentiate between their own experiences (memories) and other people’s (stories). This works out really well if you talk to people who do the same thing as you do – say, a bunch of hunters sitting around a fire swapping stories. That way, you can tap into the knowledge of your entire community (if you haven’t yet experienced it, you don’t know how common it is – hearing stories of experiences can both ameliorate your ignorance and give you ideas of what to do to deal with it).</p>
<p>But therein lies the rub. The media specialize in providing stories – really compelling anecdotes – about things that happen. The brain doesn’t differentiate based on sources, so the availability heuristic can be screwed in the <em>incorrect</em> direction. People vastly overestimate the risk of terrorism, kidnappings, and murder; but vastly underestimate the risk of car accidents, drowning, diabetes, etc.</p>
<h3>2. Confirmation Bias</h3>
<p>Confirmation bias is an old favorite of psychologists, simply because it explains so much. </p>
<p>It’s pretty simple, actually. Once you believe something, your brain tends to look for other instances of it – <strong>confirming</strong> instances. It does not, however, look for <em>falsifying </em>instances for your belief. Sometimes, your brain will even change it’s recollection of the facts to conform to your current belief (one example is the “rose-colored glasses” effect; you believe the past was better, so you unconsciously modify your memories of the past to make it match your belief).</p>
<p>But it also means once you believe something about, say, terrorism, you’ll focus on the positive (that is, supporting) instances – and ignore the others. No terrorist attacks does not affect your belief about the danger of terrorism even though a terrorist attack down – which is illogical. It’s a binary outcome, therefore one outcome value&#160; should be just a good a predictor as the other. The brain doesn’t think so.</p>
<p>A rather insidious effect of confirmation bias concerns the use of statistics. If you believe someone, and you come across a statistic (or a story) you disagree with, you’re going to scrutinize it very closely. If, however, you come across a statistic which supports your belief – then, hey, no need to question the source or the methodology, it’s obviously correct. People apply different levels of evaluation to information that conforms with their existing beliefs to information that violates their existing beliefs. </p>
<h3>3. The Urge to Conform</h3>
<p>Conformity has been studied a great deal, and the results are pretty consistent. When people are in a group and a task is difficult, you see more conformity. That is, lower confidence in the result for any one individual means that people are more willing to accept a group consensus. Funnily enough, though, each individual’s belief in the accuracy and reliability of the group consensus goes way up – even though the confidence of any individual’s conclusion is low.</p>
<p>Mr. Gardner makes the important point that conformity actually serves a good purpose. If you’re on the African plains, and everyone around you begins to get worried about a tiger in the grass – well, even if you can’t see the tiger yourself, there’s a pretty good reason to take precautions. More formally, it allows all members of a group to take advantage of the knowledge from all members of the group, and not rely on their own knowledge all the time.</p>
<p>The problem is that once a belief has taken hold in the general population, it’s bloody hard to get rid of. The combination of conformity – people fall into line – and the confirmation bias means that as a group, people don’t deal with falsifying evidence well at all. Mr. Gardner goes through a hilarious number of examples showing that (i) people say they believe something because of the evidence, (ii) you prove the evidence is wrong, (iii) people still believe it despite <em>accepting</em> that the evidence is wrong.</p>
<h3>A Passing Note</h3>
<p>In addition to those three psychological features, Mr. Gardner notes a few other issues. Here’s one I found striking.</p>
<p>It has to do with pointing out how <strong>badly</strong> people deal with numbers. People have no innate ability to deal with numerical data; though they do have a pretty good ability to deal with proportions. Unfortunately, this isn’t a good thing.</p>
<p>Mr. Gardner gives a great example. Take two groups of people: in both, tell them they are reviewing how much money to devote to improving airport safety. Tell the first group that implementing the precautions will save 150 lives; tell the second that it will save 98% of 150 lives. Consistently, people rate saving 98% of 150 lives higher than 150 lives (that is, the second group would devote more money to the project then the first group, even though they were saving objectively fewer people).</p>
<p>And don’t get started on how bad people are with probability – it doesn’t bear thinking about.</p>
<h3>A Brief Conclusion</h3>
<p><a href="http://www.amazon.com/Science-Fear-Shouldnt-Ourselves-Greater/dp/B001U0OGAY/ref=tmm_hrd_title_0">The Science of Fear</a> rests on some good psychology, and goes into a large number of examples as to how human reason fails us when it comes to knowing what to fear. </p>
<p>The real effect of the book is to persuade people to be less afraid; it reduces fear. Mr. Gardner systematically goes through most hot-button political issues, and shows how the data doesn’t back up the fear-mongering. Not only is he persuasive, but he writes in such a fashion that you’ll pick up an innate skepticism of the media (if you didn’t already have it) and a deeper skepticism for anecdotes (if you have no statistical background). </p>
<p>It’s certainly worth the time just for that. </p>
