Fair Trade As A Public Good


Fair Trade as a public good is something that the majority would lay claim to being a good principle – not everybody, but most. If the stakes are high, fair trade may be hard to stick to, but even when they aren’t so high our competitive natures may well sneak in a little stretching of the rules.

A big question of course, is who sets the rules? Also setting rules has to go along with enforcement, else we end up in situations like our current banking game. The underlying difficulty appears to be how to get people to cooperate for the general good in unregulated trading.

An ideal situation for a lab experiment, as Eriksson and Strimling spotted, did it and wrote it up last week (1). They tempted 116 students with promises of the trading floor for a Public Goods game.

From their individual cubicles, these nascent big bankers played in groups of four for multiple round before being shuffled. At the beginning of each round, they were handed a wad of 10 tokens from the forgiving public and they then decided how much to join their three unseen friends in investing in that round. Every token invested made half a token extra and the total investment was split evenly regardless of the individual investment.

Anybody who clings to the principle of fair trade as a public good would dump in most of their cash knowing that if everybody did that, all get rich. What happened? A lot of participants took a get rich line and put in very little, planning to free load on the cooperating suckers Net result? Greed triumphs over sense and cooperation, dragging everybody down. Doesn’t it sound familiar?

That was the baseline. New games were set up where the meanies were revealed and rewards and punishments were voted on by the players. No, nirvana was not attained by these young financial warriors in that Swedish stronghold of learning.

But, and isn’t it good that there can always be a but. When high meanie limits were imposed to force investment and regulated with significant fines for non-compliance, fair trade as a public good flourished.

Strong, fair regulation, firmly imposed without fear or favor, may not have been the voting choice of the financial traders, but it ensured everyone had a goodly sized pie slice. There was some latitude, so there were some winners and others not quite so well off but no cubicle banking failed.

A Shifty Look – Is He Truly Lying Or Has He A Wandering Eye?


Buying a used car? Making a political donation? Does the guy taking your money have a shifty look? If so, you’ll probably think twice before believing those silver-tongued blandishments.

The received wisdom is that if the person’s eyes keep looking up to the right, they are lying so steer clear. If the eyes keep wandering up to the left, you can go ahead, the guy is trustworthy. Well, Wiseman et al are too wise to go along with that and have put it to the test with some experiments (1).

32 canny Scots undergraduates were set up to pretend to put a cell phone in an office but in fact stuff it in their pocket and then lie about what they saw in the drawer that they put the phone into. They ran through the procedure again, but this time they actually put the phone in the drawer after rifling through so the could report out what they saw truthfully. Their eye movements were carefully logged. Coding was done both by the experimenters and another group of undergrads.

Results? No agreement with the eyes right or eyes left theories, so they got serious with videos of ‘real’ people pleading on TV for the return of abducted children. Half of the 52 videos showed people who later had compelling evidence against them that they had been responsible for the disappearance and hence were lying.

Everybody looked at the camera. No flicking eyes up to the right or left. Looks like we’re back to the polygraph, but maybe not. We pickup on a plethora of non-verbal signals and have long, long ago learned to put these together to decide if we think a guy is straight up or crooked as a corkscrew. The trouble starts when we listen to the blandishments.

Educating The Twittering Classes


How are we going to be educating the twittering classes? No brainer! By Tweeting our thumbs off. Of course the effectiveness of education has to be assessed and Edu–Twittering is no exception and there is now a definitive study available.

Last year’s Kidney Week was held during the week of November 8th and had 10,000+ participants. With their hash tag Twitter address, some of those 10,000 were able to work those thumbs, night and day, to educate, advertise, ask questions or make wisecracks. Desai et al painstaking read through all these Tweets, classified, evaluated, boxed them up, and finally, reported out in this week’s Public Library of Science (1).

The first surprise (to me) was that only 172 people of the 10,000 had twitter-engaged thumbs so the size of the Twittering Classes among the kidney cognoscenti seems rather limited, although they Tweeted at five times each on average. Uninformative Tweets in the form of advertisements took up about a third of the Tweeting space.

What makes an informative Tweet? The authors homed in on three criteria. Firstly, the Tweet had to have something to add to the Tweetee’s understanding of kidney disease, secondly, there should be some internal citations (after all a Tweet is not a tablet of stone which would henceforth be a self-evident factoid), and lastly, an informative Tweet should have ‘positive sentiment score’.

Snarky Tweeting is not going to be educative for the Tweetee except in terms of education of the Tweetor likeability rating. The general conclusion was that Tweeting is a good thing in terms of increasing informed awareness of conference topics and can be usefully employed by any conference organizer.

Perhaps academics should consider Tweeting their lecture bullet points out as they reach them (clearly with a positive sentiment). The vibration of smartphones all over the lecture hall might waken up those in the back rows.

The Cat's Coming Back!


The big news this week appears in Katie Hill’s post (1) and syndicated round the world by the BBC (2). A big Film Festival is scheduled to open in Minneapolis on August, 30th, 2012. Why is this so compelling? Because you avid fans of action movies (and sometimes inaction movies) out there can nominate your fav clip.

The clips are YouTube type videos of cats being cats being cats. Clever cats, comic cats, capering cats, conniving cats, contrary cats, comely cats, celebrity cats and, of course, let’s not forget cute cats will be hogging the limelight exclusively. No dogs will be able to cock a leg at this parade.

The cat’s coming back. Last years most viewed YouTube celebrity video was the talking dog, but with such a cat cornucopia to choose from after August, 30, dogs will be left in the dust chewing slippers.

Send off your nomination, mark your cat’s calendar and there will be no caterwauling!
