Maggie's Farm

It's about the difficulty in knowing what you don't know, and the limits of self-observation. From this site (h/t, Coyote's Arrogant Ignorance):

…people who lack the knowledge or wisdom to perform well are often unaware of this fact. We attribute this lack of awareness to a deficit in metacognitive skill. That is, the same incompetence that leads them to make wrong choices also deprives them of the savvy necessary to recognize competence, be it their own or anyone else’s.

What's a "metacognitive skill"? It's about "the ability to reflect and assess ones' own thinking and understanding."

If I did not suffer from a mild case of Dunning-Kruger, I would not be able to post anything on Maggie's Farm because "I don't know anything, I never did know anything, but now I know that I don't know...":

"Cooperation" has been the mantra of the Kindergarten-minded in our midst for years. "Competition" is supposedly male, leads to Capitalism and war and other not-nice things, and is thus evil and a human trait which must be eliminated.

Of course, I have never noticed women to be any less competitive than men. Everybody enjoys a bit of the spice of competition in life, even when you lose.

Competition vs Cooperation a phony duality which, I assume, comes from some wacky ideology. Case in point: The Dark side of Cooperation.

That is, of course, the title of Jones' classic, a companion piece to Huff's How To Lie with Statistics.

A post at Watts explains how the graph on right is designed to be misleading, to say the least.

Robin Hanson begins his piece of the above title, about "forager norms," thus:

Food isn’t about Nutrition
Clothes aren’t about Comfort
Bedrooms aren’t about Sleep
Marriage isn’t about Romance
Talk isn’t about Info
Laughter isn’t about Jokes
Charity isn’t about Helping
Church isn’t about God
Art isn’t about Insight
Medicine isn’t about Health
Consulting isn’t about Advice
School isn’t about Learning
Research isn’t about Progress
Politics isn’t about Policy

His conclusion: "We signal covertly and unconsciously because our ancestors were strongly punished for overt and conscious signals."

Signaling theory is interesting, but I do not accept the reductionistic notion that signaling is all that people do when they are together (I should say, neither does Robin H.).

At Chicago Boyz, Seizing the Opportunity to Destroy Western Civilization. A quote:

Narrative reduces personal experience to a linear progression where cause and effect seem to have a purposeful order. These narratives can then be shared with others, leading to the best definition of history ever: history is a fable agreed upon. Most personal narratives will never be the equivalent of the histories of Herodotus, Thucydides, or Gibbon; or even the fables of Aesop, La Fontaine, or Orwell. Most are simply humble habitual ways of thinking. As habits of thought, such narratives largely control how you react to unfolding events, whether it’s pricking your finger or waging a world war. 

Prof. Lindzen, in his talk at Fermilab which we posted yesterday, refers to the Prosecutor's Fallacy (aka Defender's Fallacy), which refers to a strategy of counting on a jury's inability to understand statistics, and specifically conditional probability.

Conditional probability is about the amount of linkage in events.

The simpest case: Given a red, green and blue marble in a bag, what are the odds of drawing a blue one after drawing a red one?

See the sad case of Sally Clark, who fell victim to the fallacy.

Ioannidis' Why Most Published Research Findings Are False. In his summary, he observes:

Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true. Moreover, for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias. In this essay, I discuss the implications of these problems for the conduct and interpretation of research.

I had read his paper before, but it seems especially relevant now. h/t, Classical Values.

Name that fallacy.

I would expect better from those guys.

"We have a test for a rare disease (we’ll call it Jones Syndrome), and the test is 99% accurate, but it returns a false positive in 1% of those tested (that is, 1% of the time the test returns a positive, the disease is not present). If I test positive, what is the probability that I have Jones Syndrome?"

It's not a trick question, it's a question of simple logic - and that's why it's so easy to fool juries with this sort of thing.

OK, we'll add this data:

"How prevalent is Jones Syndrome, that is, what is the probability of my having it, irrespective of any test result? We’ll say that 1 in 10000 have Jones Syndrome, so your untested probability of having Jones Syndrome is 0.01%, or 0.0001."

Answer is below the fold.  Explanation at Right Wing Prof

Via Icecap:

Leading UK Climate Scientists Must Explain or Resign

By Jenniffer Marohasy

MOST scientific sceptics have been dismissive of the various reconstructions of temperature which suggest 1998 is the warmest year of the past millennium. Our case has been significantly bolstered over the last week with statistician Steve McIntyre finally getting access to data used by Keith Briffa, Tim Osborn and Phil Jones to support the idea that there has been an unprecedented upswing in temperatures over the last hundred years - the infamous hockey stick graph. 

Mr McIntyre’s analysis of the data - which he had been asking for since 2003 - suggests that scientists at the Climate Research Unit of the United Kingdom’s Bureau of Meteorology have been using only a small subset of the available data to make their claims that recent years have been the hottest of the last millennium.  When the entire data set is used, Mr McIntyre claims that the hockey stick shape disappears completely. (Yamal: A “Divergence” Problem, by Steve McIntyre, 27 September 2009)

Mr McIntyre has previously showed problems with the mathematics behind the ‘hockey stick’.  But scientists at the Climate Research Centre, in particular Dr Briffa, have continuously republished claiming the upswing in temperatures over the last 100 years is real and not an artifact of the methodology used - as claimed by Mr McIntyre. However, these same scientists have denied Mr McIntyre access to all the data.  Recently they were forced to make more data available to Mr McIntyre after they published in the Philosophical Transactions of the Royal Society - a journal which unlike Nature and Science has strict policies on data archiving which it enforces. 

This week’s claims by Steve McInyre that scientists associated with the UK Meteorology Bureau have been less than diligent are serious and suggest some of the most defended building blocks of the case for anthropogenic global warming are based on the indefensible when the methodology is laid bare. 

This sorry saga also raises issues associated with how data is archived at the UK Meteorological Bureau with in complete data sets that spuriously support the case for global warming being promoted while complete data sets are kept hidden from the public - including from scientific sceptics like Steve McIntyre.

It is indeed time leading scientists at the Climate Research Centre associated with the UK Meteorological Bureau explain how Mr McIntyre is in error or resign. See post here.

Looks like they were cherry-picking data to get the results they wanted. Why?

Collect your best debating points here: Hawk vs. Dove on crime and punishment. Dalrymple.

As a retired prison shrink, Dalrymple knows whereof he opines. 

More fun with basic math today. Sam Savage on why we underestimate risk (h/t, Theo):

An RCT is a "randomized controlled clinical trial."

We have discussed the scientific fallacy of "data mining" here in the past in which, instead of testing an hypothesis (aka the Scientific Method), the researcher simply asks the computer to find any correlations in the mountain of collected data. That is not science.

Our readers know that a statistical correlation often - or usually - means nothing.

Junkfood Science discusses Beware the RCT. One quote:

Even medical professionals get taken by this growing technique. It’s most common when secondary studies use the database from participants in a randomized controlled trial to look for correlations — not to scientifically test a hypothesis, let alone one the original trial had been designed to fairly test. Carefully controlled clinical trials are concerned with causes and effective treatments. In contrast, multivariate analyses of large databases, with their statistical manipulations and regression computer modeling, are statistics. Statistics is about correlations. It’s not biological research.

I do enjoy it when others do my work for me.

This piece, Putting Obama on the Couch (h/t, Cafe Hayek) offers a few of my favorite cognitive biases: Wishful Thinking, Planning Fallacy, Overconfidence Effect, Attentional Bias and Anchoring Bias.

A repost from 2007:

Today during lunch I read the piece by Tyler at Tangled Web about Dawkins, who is hopeful that a "final scientific enlightenment" will destroy religion on earth. Dawkins thinks it might require that elusive "theory of everything" to do the job.

Tyler correctly notes that the "theory of everything" will never address mankind's eternal questions.

Then I followed a link in one of his commenters to an essay by physicist Stanley Jaki, who makes the case that the "Theory of Everything" must be subject to Godel's Theorem. Very interesting essay, but I cannot cut and paste from it. Read it. He discusses Stephen Hawkings' epiphany, after many years of championing the quest, that a "theory of everything" is impossible.

Then I went over to Wikipedia to refresh my vague recollections of Godel's Incompleteness Theorem, which has nothing in common with Heisenberg's Uncertainty Principle. That Wikipedia entry was good, but there was some rough sledding in it.

And that led me to the entry on The Liar Paradox.

The Liar Paradox is the old "Nothing I say to you is true,"  and the many variations thereof.

Is the Liar Paradox a true paradox, or an artifact of symbolization? I think the latter, but that reveals my bias of expecting consistency from reality. If you're curious about the approaches to the puzzle, the Wikipedia entry seems to do a good job with it.

Thus passed a very enjoyable Tuesday lunch break for this dilettante. (The Escher image is perfect, Bird Dog - thanks.)

Update: Here's a piece that takes you deeper into the Liar Paradox. Thanks, BL

Cognitive biases aren't formal logical fallacies, but I put them in my Fallacy Collection anyway.

In one short post in the realm of economics titled When Stupid is Smart, Stumbling hits on a bunch of my old favorites: The Gambler's Fallacy, The Hot Hand Fallacy, the Focusing Effect, The Status Quo Bias, Wishful Thinking, and the like.

He makes the point, as we have done here in the past, that cognitive biases save time, and that sometimes a quick, suboptimal decision is better than a slow, perfect one. Sometimes.

It's a twofer from Humbug: Name That Fallacy! 

I have always been a fan of False Dilemma. It works like a dream on the naive. Perfect Solution is for children and utopians.

"Ever done the opposite of what the experts say?"

Our friend Stumbling hits a handful of fallacies in a piece on experts. One quote:

...herein lies the purpose of experts. It’s to reinforce these mechanisms, to help people avoid the uncomfortable facts that the world is uncertain, that mistakes are inevitable, and that we are not as in control of things as we think.

Blaming experts for being wrong is like complaining that the economy is not yellow. It’s a category error so howling as to be nonsensical.

Readers know that I am a collector of formal fallacies. I keep them on the mantle, well-dusted and polished. "Saving the Hypothesis" doesn't strike me as a formal, Aristotelian fallacy, but it surely is a common thing for folks to struggle to salvage a notion in which they are emotionally invested, regardless of new data. We all do that sometimes unless we catch ourselves BSing ourselves. 

Larry Anderson at American Thinker proposed this fallacy in relation to the Global Warming Climate Change whatever topic. One quote:

I distinctly remember the first time I had an argument with someone about "climate change."  It was a warm spring day in April of 1975. I was walking across the campus at Harvard headed for lunch. A fellow classmate (we were both juniors) ran up to me. He was really excited. He hollered out:

"Have you heard? The ice age is coming. They've proven it with computer studies at MIT."

"How did they prove that there is an ice age coming with computers?" I asked my friend.

"The planet is getting colder. They have the data.  And it is going to keep getting colder. They have these computer models --"

I stopped him right there. I knew enough about computers to understand that they were not up to accurately predicting short-term weather patterns -- let alone an ice age.

"No way. Computers aren't that powerful. "

"But they have the data and they have computers!"

"I know they do. But computers spit out whatever they are programmed to spit out. Load a computer with the data that the world has been getting colder; ask it what the weather will be tomorrow, and what do you think the computer is going to tell you? The world is getting hotter? If it does you'd better get a better computer. You hungry?" I replied and I continued on my way to lunch.

The original "climate change" hypothesis was that the planet was getting colder and that it would continue getting colder. That was a very simple hypothesis and was easily proven or refuted. Planet keeps getting colder = hypothesis correct. Planet gets warmer = hypothesis incorrect.

The world got warmer instead of colder. The "climate change" hypothesis was rewritten. This time the planet was facing a catastrophic meltdown. The world was not only getting warmer -- it was going to keep getting warmer at an ever increasing and life-threatening rate.

Think you're smart? That could mean that you are not. Always listen to different view before rejecting them. From a piece with the above title at Overcoming Bias:

...it seems clear that mostly what is going on is that we all misjudge our ability and task difficulty. 

You can say that again.

The article in Zombietime, The Left's Big Blunder, is about the famous Asch experiments on conformity.

Obama supporters presume that increasing Obama's perceived support will induce informational conformity in the American public. In other words, Obama supporters operate on the assumption that individual McCain supporters or undecided voters will in actuality change their minds about who to vote for if they perceive that a majority of people are supporting Obama. The imagined line of thinking is, "Gee, if so many people like this Obama guy, then my impression of him must be wrong; I trust the group's wisdom more than my own impressions."

I suppose the Dems' efforts to portray Obama as inevitable and wildly popular are an effort to exploit the conformist tendencies in people, but this seems rather usual in politics. However, the article offers a good depiction of how conformity can distort our thinking and cause us to doubt ourselves and our lyin' eyes. 

The desire to fit in and to be accepted is strong in all of us. It's important for survival, but we need to try to make room for thinking for ourselves too, based on our experience and not on received opinion.

Just as professional journals and newspapers are more interested in printing pieces that support hypotheses rather than papers with negative findings, so we all tend to spend more time discussing the risks of action rather than the risks of inaction.

That seems to be human nature, but it ain't rational and, fortunately, people vary across a spectrum of activity/passivity.

Passive people worry about the risks of action. Active people worry about the risks of inaction. I am more-or-less in the middle.

To discuss that half-intelligently, though, I first need to review the notion of Type 1 and Type 2 errors, now that we have taken a look at the null hypothesis a couple of days ago. 

A Type 1 error, also known as False Positive, is the error of erroneously rejecting the null hypothesis. In other words, it supports a connection which does not really exist.

A Type 2 error, or False Negative, is the error of wrongly accepting the null hypothesis. In other words, it says nothing is there, when it is, in fact, there.

For example, a blood test which has a 10% False Positive rate will wrongly tell you that there is an abnormality 10% of the time. A blood test with a 10% False Negative rate will miss an abnormality 10% of the time.

For another example, convicting an innocent person is a Type 1 error; letting a guilty person go free is a Type 2.

Depending on the matter at hand, either sort of error could have worse consequences. A Type 1 error in a death penalty case is a grievous error. But sometimes you need Type 1 errors.

My favorite example of a good Type 1 error is in the emergency treatment of appendicitis. Since medical diagnosis contains both art and luck as well as science, some error rate is inevitable unless you have the diseased organ in hand. But since a False Negative diagnosis would have dire consequences (ruptured appendix), it is necessary to do some unnecessary appendectomies on patients who might have appendicitis, but do not turn out to. In the case of emergency appendectomies: one study indicates that the Type 1 error rate is around 10%, with 18% False negatives. I would have guessed that the False Positives would be higher, and you could argue that there is room for them to go higher. The point is that, with appendicitis, you want to minimize your False Negatives by having more False Positive diagnoses - by being deliberately biased against the Null Hypothesis that there is nothing there, but without cutting open everyone with a bad stomach ache.

Thus that is the opposite of what you want in a justice system, where the null hypothesis of innocence is presumed in order to minimize False Positives.

From Wiki:

The conjunction fallacy is a logical fallacy that occurs when it is assumed that specific conditions are more probable than a single general one.

The most oft-cited example of this fallacy originated with Amos Tversky and Daniel Kahneman ^[1]:

Linda is 31 years old, single, outspoken, and very bright. She majored in philosophy. As a student, she was deeply concerned with issues of discrimination and social justice, and also participated in anti-nuclear demonstrations.

Which is more probable?

1. Linda is a bank teller.
2. Linda is a bank teller and is active in the feminist movement.

85% of those asked chose option 2 ^[2]. However, mathematically, the probability of two events occurring together (in "conjunction") will always be less than or equal to the probability of either one occurring alone.

Thus is the brain seduced by detail. All writers know this fact. Which works best: "Dick wore a hat." or "Dick wore a green felt hat with a pheasant-feather hatband."

One of my favorite sites to visit, Overcoming Bias, wonderfully discusses When not to use probabilities. He says:

The laws of probability are laws, not suggestions, but often the true Law is too difficult for us humans to compute.  If P != NP and the universe has no source of exponential computing power, then there are evidential updates too difficult for even a superintelligence to compute - even though the probabilities would be quite well-defined, if we could afford to calculate them.

So sometimes you don't apply probability theory.  Especially if you're human, and your brain has evolved with all sorts of useful algorithms for uncertain reasoning, that don't involve verbal probability assignments.

Those algorithms are "gut feelings." Often wrong, often accurate. There is one thing that I know for certain: the more time I have to think about how to hit a tennis ball, the more likely I am to blow the shot. He also says:

In general a rationalist tries to make their minds function at the best achievable power output; sometimes this involves talking about verbal probabilities, and sometimes it does not, but always the laws of probability theory govern.

If all you have is a gut feeling of uncertainty, then you should probably stick with those algorithms that make use of gut feelings of uncertainty, because your built-in algorithms may do better than your clumsy attempts to put things into words.

An argument ex silentio claims "You respond with silence, thus I am proven right."

From Wiki: 

"In general, the claim that the absence of something demonstrates the proof of a proposition. An argumentum ex silentio ('argument from silence') is an argument based on the assumption that someone's silence on a matter suggests ('proves' when a logical fallacy) that person's ignorance of the matter or their inability to counterargue validly."

Of course, there are many reasons for silence besides an inability to make a counterpoint, including a simple lack of interest in pursuing a line of discussion or, as I have often found myself doing in debates with Liberals, reverting to silence out of a feeling of futility.

In the blog world, the common expression "crickets chirping" is a cute way of implying an ex silentio argument. Sometimes it's right, sometimes an error.

Augean Stables has a pretty good example of this fallacy in a debate he is engaged in about the al Durah affair.

...in proportion as the evil decreases the denunciation of it increases; and as fast as natural causes are shown to be powerful there grows up the belief that they are powerless.

Herbert Spencer was a giant of his time. His socio-political "law" is discussed at Cafe Hayek.

You have the best, most modern, and most widely available medical care in the world? But it's terrible - because some few fall through the cracks! You have terrible storms, with wind and rain? Surely governments or the UN can fix that!

Spencer's Law surely applies to many areas of life today.

The technical definitions of solipcism and sophistry tend to elude my memory. I study them, and a month later they slip away. "Sophistry" is of course often used as a general insult towards arguments with which one might disagree, but that usage degrades the meaning.

AVI did my work for me today, on sophistry. His handy practical definition: "Sophistry is a phrase so neat you can't see the loose end that would unravel it. It's flawless, but wrong."  Sleight-of-mind.

One of the examples he offers is:

You cannot simultaneously prevent and prepare for war.

Hmm, wait a minute - why can't you do both? I'll offer this one:

If the glove don't fit, you must acquit.

Wait a minute - a glove gets to make the decision?

One more:

Heard from a New Zealand interviewer last week re global warming:
"It's very important for New Zealanders to try to help, even if it doesn't make a difference."

It is? Futility is an essential part of the Kiwi national character?

Thus sophistry is designed to defeat thought, not to provoke thought. Such assertions are designed to ward off that "Hey, wait a minute, does that make sense?" reaction. Always check the premises before discussion, even if they sound OK. Or especially if they sound OK.

You can read AVI's piece here.

From the Wiki entry:

"Anchoring or focalism is a cognitive bias that describes the common human tendency to rely too heavily, or "anchor," on one trait or piece of information when making decisions."

The notion of Anchoring Bias comes from Cognitive Psychology, not from Logic.

I suppose it could be a fancy way of saying that sometimes we cannot see the forest for a single tree, and are thus "prevented" from considering all of the relevant facts or options.

This sort of cognitive bias typically operates, as do most biases, unconsciously or reflexively, as a gravitational pull towards some decision or reaction.

A true example (but not an unconscious one, from the Mrs., on considering what new car to buy): "It just has to be the right shade of maroon."

Another example, reported to me by a pediatrician friend: "I ordered a brain MRI ($800) for a 10 year-old kid with tension headaches.  Totally unnecessary, and I realized afterwards that I did it because I had read a journal article over the weekend about an undiagnosed brain tumor in a 10 year-old."

Thus, like most fallacies and biases, it's part of the brain's effort to be efficient or persuasive in its heuristics by tossing out an anchor on one detail (ouch - that's bad writing), and often might, but doesn't always, lead to the most realistic choices.

As we learn more about how our brains make decisions outside of our awareness, being aware of, and being able to monitor, the shortcuts our brains take should serve us well.

I could not resist this free association, having recently learned that "Anchors Aweigh" was written in 1906 to be a swinging football song (which it is):

We rarely miss an excuse to discuss this law of nature. From a piece by Rob Norton at the Library of Economics and Liberty, which begins:

The law of unintended consequences, often cited but rarely defined, is that actions of people—and especially of government—always have effects that are unanticipated or "unintended." Economists and other social scientists have heeded its power for centuries; for just as long, politicians and popular opinion have largely ignored it.

The concept of unintended consequences is one of the building blocks of economics. Adam Smith's "invisible hand," the most famous metaphor in social science, is an example of a positive unintended consequence. Smith maintained that each individual, seeking only his own gain, "is led by an invisible hand to promote an end which was no part of his intention," that end being the public interest. "It is not from the benevolence of the butcher, or the baker, that we expect our dinner," Smith wrote, "but from regard to their own self interest."

Most often, however, the law of unintended consequences illuminates the perverse unanticipated effects of legislation and regulation. In 1692 John Locke, the English philosopher and a forerunner of modern economists, urged the defeat of a parliamentary bill designed to cut the maximum permissible rate of interest from 6 percent to 4 percent. Locke argued that instead of benefiting borrowers, as intended, it would hurt them. People would find ways to circumvent the law, with the costs of circumvention borne by borrowers. To the extent the law was obeyed, Locke concluded, the chief results would be less available credit and a redistribution of income away from "widows, orphans and all those who have their estates in money."

Read the whole thing.

The brilliant one-time lawyer and Warren Buffet partner Charlie Munger (I think the cynical - or should I say skeptical - Munger does the deep thinking, and Buffet is the practical guy) loves Robert Cialdini, who writes about influence and persuasion. Here's Cialdini's The Psychology of Persuasion.

(Also, a lifetime of thought is condensed in Poor Charlie's Almanac: The Wit and Wisdom of Charles T. Munger)

You bought a house two years ago, no money down, with a one-year teaser interest-only rate. You knew what you were doing: you gambled that in a year you might be able to make the second year's payments and, if not, the house would have more equity in it. That equity would belong to you.

Can you really blame the mortgage broker?

Or, maybe, you bought a second house or two to rent out, as an investment a speculation, with that same deal, planning to flip it when the time seemed right.

You had no skin in the game, except for your hope for wild profit - it was all the bank's money. You had nothing to lose.

Now the house is worth less than your buying price, and you can't keep up with this year's payment because you didn't get the promotion you hoped for. Logical (if dishonorable) person that you are, you consider dumping your committment and going back to renting again - or hoping that the taxpayer will somehow rescue your reckless real estate  investment gamble.

Well, not to worry. The Dems want to bail you out. McCain thinks it's nuts, and so do I. Am I a heartless Scrooge? In truth, buying a home mortgage is no different from an LBO, or buying options on margin. Didn't these people ever play Monopoly?

Newspapers and pandering politicians call these unlucky gamblers "homeowners," but they aren't. They own nothing but debt and a contract.

As prices drop, houses are becoming more affordable to credible buyers instead of crazy gamblers. And, in ten years, there will be another housing bubble. You can bank on it.

If your house is an investment, and not a home, sell it then.

Editor's note: There are comparable moral hazards with rescuing the banks. See Fed eyes Nordic-style bank nationalization. I am not convinced that we are at that point. Power-people see every problem as an opportunity for a power and/or money grab. Just label it a "crisis."

"Act only according to that maxim whereby you can at the same time will that it should become a universal law."

Was Immanuel Kant's Categorical (ie absolute) Imperative just a fancy way of coming around to the Golden Rule, as Bird Dog suggested the other day?

Kant's ethics fall in the category of deontologogical (ie duty-centered) absolutism: he said that one should not lie even to save a life (but I doubt that he ever found himself in that situation).

To my simple mind, teleological (outcome-based) ethics, like Utilitarianism, are not ethics or morals at all: our daily actions need to be teleological most of the time, but that is about practical judgement - not morality. As a foundation for a moral code, teleological ethics are insidious and dangerous.

Like most people, my moral codes are not carefully thought through. They are mostly inherited from a long line of Yankee Puritans, and Christianity-based. Thus far, they have kept me out of the clink, but have not protected me from doing my share of stupid, cruel, or selfish things. Like most people, I only focus on morals when presented with a moral dilemma that comes up on the radar, because the rest of the time I am on moral autopilot. I guess I'd have to say that my morality is neither deontological nor teleological, but mystical as G.K. Chesterton would say (Ten Commandments, The Great Commandment, etc) in its origins, with a dose of my personal obsessionalism on top.

Still, it's an interesting thought experiment to spend a day thinking about how - or whether - my daily decisions might be different if I consciously and deliberately pretend to adopt a different moral foundation.

Image: Immanuel Kant

Dr. Bliss comment: You are right that one's morality is not arrived at by deliberate thought. Guilt and morality are quasi-internalized during youth. After that, it's all about just learning the rules, laws, and socio-cultural expectations to avoid a messy life. Maybe I will post a draft of a piece I once wrote on the subject for a lay audience.

I do not think that I like Eliot Spitzer, but I don't know him as a person. I do know that if he came to me for comfort and help, I would be happy to offer it to him as a fellow flawed, sinful, and foolish human. I would pray with him for himself and for his family, who are surely suffering for his idiot behavior.

However, his story got the brain thinking about how, if you do 999 good, charitable, loving things in your life, and one bad, illegal thing (not that Spitzer is in that category - I doubt it, based on how he handled his powers as a prosecutor) - you are screwed if you get caught.

Nobody will care about the other 999.

That is why cops say that there are only two kinds of people - crims that haven't been caught, and those who have been. One must be careful in this life, because it can blow up in an instant.

Sowell notes that the cost of incarceration in some states exceeds the costs of higher education.

The point, of course, is that when people (not Sowell) talk about those costs, they ignore the monetary and social costs of letting those folks loose on us. That's the fallacy. On the other hand, MA can send 'em all to Harvard for all I care, if they want to.

It has nothing to do with Rudy Giuliani's "broken window" approach to restoring civilization to NYC (which is no fallacy - it worked well, because providing latitude in the little things, filth, petty crimes, bums and addicts sleeping in parks, hostile squeegee men, etc. implicitly endorses latitude in bigger things, leading to an atmosphere of anarchy that nobody wants to experience).

The excellent Bastiat QQQ yesterday brought it to mind. Bastiat's famous parable of the Broken Window explains how a kid breaking a window, despite the expenditures to repair it, on the bottom line does no favor to the village's economy.

While some Keynesians might argue otherwise, I would make the case that, although maintenance of things we care about is a large part of an economy - cars, houses, boats, gardens, horses, dogs, bodies, etc - the fallacy there is the failure to reckon the opportunity cost of the money on the part of the window-owner.

I recently posted on the subject of the pseudo-rationality that ensues when the costs of an event are calculated, but is not compared to the costs of inaction or of alternate actions - or the advantages thereof.

If anyone were to calculate the global economic advantages of global warming, for example, I think everyone would be praying for it - but I doubt it will occur in any meaningful way.

From Mediocracy:

Steven Pinker has become a bit of a hero for those not entirely seduced by the mediocratic project. He is perhaps the only prominent academic prepared to trumpet the idea that ability is at least partly inherited. This idea has, apparently, become highly controversial, a fact which a visiting Martian might find rather bizarre. When the Financial Times reviewed The Blank Slate, it treated Pinker as some kind of firebrand radical, referring to his "dangerous work", and that it "would be best if it didn't get into the hands of those who would use it to terrifying ends".

and

... if people's sense of well-being comes from an assessment of their social status, and social status is relative, then extreme inequality can make people on the lower rungs feel defeated even if they are better off than most of humanity ... The medical researcher Richard Wilkinson, who documented these patterns, argues that low status triggers an ancient stress reaction ... Wilkinson argues that reducing economic inequality would make millions of lives happier, safer, and longer. (ibid)

An example of pseudo-rationality: in this case, an incomplete analysis that looks cogent but is actually biased. What it leaves out is (a) that we can only reduce ex post (= after the event) inequality by changing the rules of the game, and (b) that this is certain to have its own associated costs, which are left out of the equation. The need to compete for status is no less likely to be an important human drive than the need for status itself. If you make it harder for people to win, that may also generate stress. While there is plenty of research purporting to show the stressful effects of inequality, I doubt there is much (if any) looking into the stressful effects of intervention, restrictions, red tape, or deselection on ideological grounds (the flip-side of affirmative action).

Mediocracy thus presents an excellent case of pseudo-rationality in which the human costs of an intervention are ignored. In my experience, failure to enter these costs into calculations generally results in further problems which also end up begging for another government intervention to try to correct. Thus governments and agencies grow, on the fertile soil of their own manure.

It turns out that Aristotle, not Jean Buridan, first came up with the logical paradox of the hungry, thirsty ass who dies, paralyzed by indecision between a bucket of water and a pile of hay.

Viking mentions the Dem version, with its apparent solution:

It's the political equivalent of Buridan's ass: with no defining issue to differentiate the candidates, Americans gravitated towards the one you'd like to have a beer with and watch a little football.

Our editor mentions another one: A MA Yankee torn between his attachment to the Berkshire Hills and Cape Cod. (God forbid that leaves you stuck inside of Worcester, MA with the Memphis blues.)

Via Overcoming Bias:

A superintelligence from another galaxy, whom we shall call Omega, comes to Earth and sets about playing a strange little game.  In this game, Omega selects a human being, sets down two boxes in front of them, and flies away.

Box A is transparent and contains a thousand dollars.
Box B is opaque, and contains either a million dollars, or nothing.

You can take both boxes, or take only box B.

And the twist is that Omega has put a million dollars in box B if Omega has predicted that you will take only box B.

Omega has been correct on each of 100 observed occasions so far - everyone who took both boxes has found box B empty and received only a thousand dollars; everyone who took only box B has found B containing a million dollars.  (We assume that box A vanishes in a puff of smoke if you take only box B; no one else can take box A afterward.)

Before you make your choice, Omega has flown off and moved on to its next game.  Box B is already empty or already full.

Omega drops two boxes on the ground in front of you and flies off.

Do you take both boxes, or only box B?

Decide, then read about it.  Yes, it is related to the Prisoner's Dilemma.
