More from the rolls of Kevin Lewis' blog:

• If you want to capture a little more self-control, just think of money.
• Natural (and other) disasters may make us all a little dumber. (But don't take these results to heart - they're based on a study of 16 people.)
• Snakes and guns: a study in how threats to our ancestors get translated into threats today.
• How we self-segregate - even when we don't necessarily want to.
• We prefer masculine vs. feminine leaders depending on whether or not we're at war.
• Why do institutions look so similar across the globe? Maybe it's because humans like them to be that way.
• America in Italians' eyes: father figure or nation of barbarians, depending on ones political orientation.
• Is democracy good for us? Only in the grand historical sweep of things...
• But whether or not democracy makes us wealthy, wealth tends to make us democratic.
• Before Facebook, hunter gatherers had social networks of their own. And they looked surprisingly similar.
• Foraging robots help explain why groups develop certain communication systems: they balance efficiency and robustness.
• A new entrant into the club of "what makes us human" theories: our brain's development of "frontal feedback".
• There's evidence that we become smarter about predictions when real money is on the line - but that's not the case when it comes to optimistic football fans.
• Low on glucose? You're conscious thinking powers may fail on you - but, don't worry, your unconscious thinking has you covered.
• There's evidence groups can make us collectively dumber: now they're saying pairs may do the same.
• Want to emphasize differences in performance? Use small numbers.
• Get creative: try to experience unexpected unusual events. Or decrease your latent inhibition. Or practice the generic parts technique.
• Anxiety can make us more vigilant and aware, but it also debilitates performance.
• The risk of finding explanations for inconsistencies: you may start missing inconsistencies altogether.
  
• Fines can get us to change our behavior - but only for a limited time.
  
• Ideologues create God in their ideological image.
• The newest installment in the Jonathan Haidt's five fundamental values theory: they do a good job of picking people's preferences on issues like immigration, abortion and same-sex marriage.
• When we're freaked out by death (ie "mortality salience" is high), we have a harder time understanding reading passages that conflict with our views.
• Curiosity: an antidote to aggression.
• An argument for matching campaign funds, using NYC as a model.
• Representative democracy may not be perfect, but given voters' "bounded rationality" it may be better than pure democracy or technocracy.
• Interest groups on not just good for lobbying - they also stimulate civic participation.
• Conservatives may not be happier because they're "system justifiers" - but because they can afford to be part of more groups.
• We look up to people who break the rules - as long as they're doing so to benefit the group.
• How big is someone's Facebook network? Just check the size of their "temporal sulcus".
• Humans are a cooperative species; one of the reasons we are (or can be) so is because we're so diverse.
• I'm not going to pretend I understand this, but public information can make us worse off when we're also picking up private information.
• Peers go to colleges their peers prefer.
• Want to keep free-riders in your group in line? Disapproval works better than approval. So do small penalties.

• In Finland at least, adding a couple years of required education doesn't increase citizen participation.
• But going "mobile" - if you happen to have a large network - can make you more politically involved.

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?

recent research

Keeping up with Kevin Lewis' log of recent research:

• Our sacred values - like other rules - are generally not up for sale.
• It really is the thought that counts - whether we're punishing free-riders, condemning the schadenfreuders, or enjoying the sweet taste of a gift.
• The loser's paradox: take a losing strategy, add in some fear, and you get more losing strategy.
• We're better at predicting others' behavior than our own.
• You're not imagining it: people are more likely to remember "that one time" you messed up.
• Raising money for a worthy cause? You may want make it hurt. Or get prospective donors to think of their childhood. Or be sure to focus on the somewhat rich and forget about the mega-rich. Or get them to do something exceptional or odd first. And don't forget to give your donors public recognition.
  
• Money changes everything - even if you're in kindergarten.
• Do people give to charities for the "warm glow" it gives them - or because they feel uncomfortable saying no? It's not the warm glow.
• Not sure why you would do this, but if you're ever thinking of subsidizing sharing, think again.
• More evidence that we're not really good at assessing our politicians' performances.
• Good news from the campaign front! We're more likely to hear positive campaign themes.
• Want to cut back on pork? Try term limits.
• Do voters prefer professionalized legislatures? Depends on their ideology.
• High voter turn-outs are great - unless you don't like budget deficits. Then again, deficits may not be a risk if voters are electing highly popular parties.
• Want to be smarter? Stop all that thinking and go with your gut. Pour yourself a drink.
• If life is a box of chocolates, we should live each day as if we're eating the last truffle.
• Groups are often thought to stifle creativity - but that may depend on how creative the groups are.
• Need to persuade someone? Try asking them to pretend to support some other random proposition first.
• How to get crowds to be wise about complex problems.
