a refreshingly candid politician...

... being honest about his dishonesty:

“We all know what to do, we just don’t know how to get re-elected after we have done it.” 

- Jean Claude Juncker, Prime Minister of Luxembourg (speaking of the Euro Crisis, but really could be speaking about any policy anywhere).

"dark" social

Ever get the feeling Facebook has taken over our online lives?

Alex Madrigal at the Atlantic thinks "social networks" only account for less than a quarter of the social web - at least when it comes to link-sharing. The rest comes from emails, chats, texts - what Madrigal calls "dark social" (because you can't track exactly where those links come from).


Social traffic to the Atlantic. For the rest of the web the percentage of "dark social" is more than 3/4ths.

what to not forget

Yesterday was September 11th, and try as hard as I could not to look at my Facebook page (okay, not very hard) I couldn't help avoiding all the reminders to "Never Forget."

Yesterday was also the second meeting in my intro to Social Psych seminar, where we get to read all the oldies but goodies in psych research. This week's discussion was Milgram's 1960's Yale study. You've almost certainly heard of it: New Haven residents innocently came in to participate in a study about "learning" and within an hour found themselves obediently administering electric shocks, starting at 15 volts and moving up to 450, to another "participant" (actually a "confederate" in on the game). Almost all participants started to be concerned when the confederated began hollering in pain and begging to be released, but most - over 60% - continued to flip the shock switch all the way up to 450, even after the screams from the confederate suddenly stopped, leading them to wonder if they had killed the guy. What's unsettling about the study is not just that so many people easily follow orders to harm another, it's that these participants look - and act - like such nice people. They're intensely concerned about the welfare of the person they're zapping, visible writhing in metaphysical pain themselves, yet they zap away.

In light of the Milgram study, I couldn't help wonder what it was I was supposed to be not forgetting on September 11th. When we hear the words "Never Forget" in reference to the Holocaust, the lesson is pretty clear; at least according to the tour guide in Israel's Holocaust museum, we're never to forget that humans, even when they appear to be at the height of civilization, are capable of horrendous acts. And, by humans, we're talking about me and you. It's the same message Milgram hoped to get across (along with Hannah Arendt and many others): it doesn't take much to turn us all (or a good 90%+ of us) into willing executioners.

But I'm pretty sure that is not what all those images of the twin towers with the words "Never Forget" were trying to tell me. I know some were saying we should never forget to honor the many innocent lives that were lost in the tragedy. But perhaps just as many don't want to forget that "bad people did something really bad to us."

I agree a noble society always remembers those who were sacrificed in its name (AQ was taking aim at all of us, and just happened to hit those 3000). But I don't understand what we gain out of remembering that some people once tried to hurt us. There's not much to learn beyond anger and paranoia. 

We're much better off remembering Milgram and, instead of hoping we can eradicate all the bad guys from the earth, being very vigilant that one day we don't become the bad guys ourselves.

religious inconsistencies

If there is a definitive example of humans' ability to explain away factual inconsistencies in order not to disturb their belief system, it's got to be religion - as this image reminded me this morning:



You don't need to take a course in biblical exegesis (even though I did years ago - and I highly recommend you do too) to admire the creative rationalizations of Judeo-Christians (and, I'm sure, other religious believers) to justify why, for example, it makes perfect sense that we're all descended from Adam and Eve, a couple who only had sons.

But what grates is how many of those same inconsistent believers point to others and demand consistency between their holy book and their religious beliefs - for example, how some Judeo-Christians pick out passages in the Koran and claim that Islam is inherently violent. That is an inconsistency I cannot admire.

the wisdom of heuristics

Yesterday my friend Bernstein was wondering why it is that modern day humans seem so bad at assessing relative risks. 

While there's a mushrooming field of psychology that details how our many cognitive biases make us poor natural statisticians, there are good reasons for our brains not to operate in strictly Bayesian ways. 

For one, our brains were designed in a time when relevant numbers rarely went above 150 (the number of people we were likely to encounter in life). 

More importantly, back when we all lived on the Savannah, genes would do well to err on the side of being overly-cautious. 

The example I gave Bernstein was how you wouldn't really care about sample size or the denominator of a trend when it came to lions: seeing one friend mauled by a lion would be evidence enough that avoiding lions was a good idea. But today I bumped into an xkcd comic that illustrates how, even today, we're more often better off not thinking like scientists or statisticians:


By the way, for one of the best overviews of how our illogical minds do a good job of simulating logic most of the time, take in Kathryn Schultz's Being Wrong.

Sunday morning PETA philosophizing

Another fascinating article suggests that humans became the world's top dogs in large part because of their co-evolution with actual dogs:
"Domesticating dogs clearly improves humans’ hunting success and efficiency—whether the game (or the dog) is large or small. The same must have been true in the Paleolithic. If Neandertals did not have domestic dogs and anatomically modern humans did, these hunting companions could have made all the difference in the modern human–Neandertal competition."
I've never been a proponent of animal-rights (I usually figure we should get human rights taken care of first), but if certain species co-evolved with us and are responsible for our survival and good fortune, you can kind of argue that those species are us. That is, if humans wouldn't exist without dogs, that makes our two species almost one meta-species. If that's the case, then dogs might deserve at least a few of our rights.

inattentional obliviousness

A potentially stomach-churning story in the news today: the teen who recently was rescued after drifting at see for 28 days is now suing Princess Cruise Lines - for allegedly sailing by him and his two friends on the 16th day of his ordeal. (His two skiff-mates were alive at that point but did not make it to the 28th day.)

The worst explanation for this painful story is simply that the ship saw the castaways but did not want to bother picking them up. But this is unlikely. Sailors have a strong ethic of the sea; if a member of the crew were to have seen the drifters they certainly would have done the right thing. As for the passengers, all humans - especially Americans - are just not callous enough to let people perish. We can be a self-absorbed and selfish race of people, but we love being heroic - particularly when it's relatively safe and easy to be so.

The more likely - and least upsetting -explanation is just that no one saw the teens' motor boat. That the drifters could see the cruise ship - and even the passengers on it - is not a surprise. The cruise ship is not only a bit bigger than the teens' fishing boat; more importantly, the teens were looking for a boat to, of course, save them. Passengers on the tourist ship would not be similarly looking for a small boat adrift at see; even if the boat had been visible to tourists on deck, by virtue of not looking for a small boat they may not have "seen" it. This is a phenomenon psychologists call "inattentional blindness." In essence, we see what we are looking for - or what we expect to see. If you're a Hitchhiker's Guide fan, you'll be familiar with this concept as the spaceship you cannot see because you're not expecting to see a spaceship. In real life, it happens often with lifeguards who often don't see bodies lying at the bottom of pools

Another likely - but more disturbing - explanation is that passengers did see the teens' motor boat, but it didn't occur to them that there was anything to alert the crew about. This is the theory that makes my heart sink. I don't know how far out the cruise ship was, but it must have been far enough for there not to be land in sight, nor sight of any other boat. Is it possible that passengers saw a small boat in the middle of the sea and not one thought "that is odd, what is such a small boat doing out in the middle of nowhere?" - and were not even curious enough to ask a crew member if that might be cause for concern? I, sadly, believe it is entirely possible. It's what I'd call "inattentional obliviousness" - the idea that if someone is not standing up and screaming "there's a problem here!" everyone assumes everything is smooth sailing.

Next day addendum: Turns out I was pretty much wrong about everything - about the tourists not seeing the boat and not imagining anything was wrong and, most worrisome, about what the crew would do if they knew about a boat in distress. At least according to NPR.

when academics need to take a step back

Ivory towers are well known to have a distorting effect on academics' relationship to reality. Even so, the occasional study seems so distorted it deserves special note:

Trial by Battle, Peter Leeson, Journal of Legal Analysis, Spring 2011

Abstract: For over a century England's judicial system decided land disputes by ordering disputants' legal representatives to bludgeon one another before an arena of spectating citizens. The victor won the property right for his principal. The vanquished lost his cause and, if he were unlucky, his life. People called these combats trials by battle. This paper investigates the law and economics of trial by battle. In a feudal world where high transaction costs confounded the Coase theorem, I argue that trial by battle allocated disputed property rights efficiently. It did this by allocating contested property to the higher bidder in an all-pay auction. Trial by battle's "auctions" permitted rent seeking. But they encouraged less rent seeking than the obvious alternative: a first-price ascending-bid auction. (italics mine)

Why, oh why, Peter would you bother to argue such a thing?

nice guys vs. jerks and representativeness

"Nah, I can't wear my glasses out. They make me look nice - and everyone knows girls don't want to date nice guys. Women like the bad boys."

This is my neighbor Andrew giving me that tired, woeful explanation for the seeming success of jerks that so many New York men (nice and not nice) take as gospel. After recovering from the profound despair such misconceptions hurl me into - I pulled out a pen, grabbed a napkin and marshaled the teachings of Daniel Kahneman to set Andrew straight. I thought it a worthwhile service for the single women of New York to likewise educate other men:

Women don't like jerks. They do like cool, confident. Ask any woman. This is god's truth.

What confuses men off is what Kahneman calls the Representativeness Heuristic. Men (and, yes, women) don't tend to think like statisticians; instead we make categorizations based on correlations. (In their most insidious forms these categorizations are called prejudices, but usually they're less harmful.) Andrew, like many of his sex, was categorizing "bad boys" (or "jerks" as I'll call them) as "cool" and "nice guys" as "uncool."

Andrew's View


Now, Andrew isn't necessarily wrong about this categorization. Let's even say he's right: jerks do tend to be cool and nice guys uncool.

But that still doesn't mean women like jerks. What happens is that nonconfident, uncool guys (the kind of guys women don't, in fact, like) almost always are nice. This is so because they don't really have a choice; if you're unconfident and a jerk, you don't even get a first date. Cool, confident guys, however, have a choice: they can be nice guys or jerks.

Let's say that the world is made up of 50% confident guys and 50% nonconfident. To keep our model simple, assume all of the uncool guys will be nice guys, but that 50% of the cool guys will be nice and 50% will be jerks. You get the picture below.



You can see that most of the nice guys, yes, do happen to be uncool, while virtually all of the jerks are confident. Thus the misleading heuristic of "nice=uncool".

But don't be fooled, gents. Ladies will put up with the cool, confident jerks, but what we all want - and what I humbly recommend you aspire to be - is the cool, confident, nice guy.
