Maybe in 2006? No. I'm not predicting that.

punishment-and-security

There is a very article in the NY Times about how groups can profit by punishing members, in particular, by punishing free riders.

In the experiment, investigators at the University of Erfurt in Germany enrolled 84 students in the investment game and gave them 20 tokens apiece to start. In each round of the game, every participant decided whether to hold on to the tokens or invest some of them in a fund whose guaranteed profit was distributed equally among all members of the group, including the "free riders" who sat on their money. Because the profit was determined by a multiple of the tokens invested, each participant who contributed to the fund enjoyed less of a return than if the free riders had done so as well.

Perhaps there is a lesson for infosec professionals in this post on the Affect heuristic on Overcoming Bias:

Suppose an airport must decide whether to spend money to purchase some new equipment, while critics argue that the money should be spent on other aspects of airport safety. Slovic et. al. (2002) presented two groups of subjects with the arguments for and against purchasing the equipment, with a response scale ranging from 0 (would not support at all) to 20 (very strong support). One group saw the measure described as saving 150 lives. The other group saw the measure described as saving 98% of 150 lives. The hypothesis motivating the experiment was that saving 150 lives sounds vaguely good - is that a lot? a little? - while saving 98% of something is clearly very good because 98% is so close to the upper bound of the percentage scale. Lo and behold, saving 150 lives had mean support of 10.4, while saving 98% of 150 lives had mean support of 13.6.

The post also shows that people tend to over-estimate the value of going with known brands, even though they might not add any extra value:

Ganzach (2001) found the same effect in the realm of finance. According to ordinary economic theory, return and risk should correlate positively - or to put it another way, people pay a premium price for safe investments, which lowers the return; stocks deliver higher returns than bonds, but have correspondingly greater risk. When judging familiar stocks, analysts' judgments of risks and returns were positively correlated, as conventionally predicted. But when judging unfamiliar stocks, analysts tended to judge the stocks as if they were generally good or generally bad - low risk and high returns, or high risk and low returns.

But perhaps you don't have time to consider all this, because you've got a deadline!

Finucane et. al. also found that time pressure greatly increased the inverse relationship between perceived risk and perceived benefit, consistent with the general finding that time pressure, poor information, or distraction all increase the dominance of perceptual heuristics over analytic deliberation.

In the latest completely stupid culture of fear incident, a couple of Hash House Harriers were arrested for putting flour on the ground near an Ikea. The sad part, well one of the sad parts, is that the man arrested is a German citizen who joined the running group to meet friends. Another sad part is this quote from the city spokesperson:

Mayorga said, "We can't take any situation lightly. We didn't know who these people were. We didn't know what this substance was and in the best interest of the citizens of New Haven, we had to take it seriously."

I'm not an expert, but I'm pretty sure there is no chemical or biological agent that is effective by being thrown on the ground in pile outside. What would be good is for the city to have a process whereby an uninformed officer can make a call to someone who then says there is no need to call the Police, Fire, Health, state police and FBI for someone playing a harmless game.
