Are irrational economic choices baked into the human psyche?

By | August 5, 2010, 8:51 AM PDT

There’s no question that many members of our species make terrible and irrational economic choices — from risky real-estate bets to market panics to outright fraud.

But are these lousy decisions the product of lack of proper oversight and regulation — as frequently gets discussed now — or something baked into our very cognitive processes as a species?

Laurie Santos, who runs the Comparative Cognition Laboratory (CapLab) at Yale, set out to prove just that, establishing an “economy” of sorts among a group of primates, and observing the interactions as they deal with the exchange of food for “money.”  What she found was astonishing, as she related in a recent presentation at the TED conference.

The monkeys in Santos’ experiment were given metal tokens that would function as money, and were taught that the tokens could be exchanged for food. Human “salespeople” — student lab workers — would sell monkeys the food at different prices, so the monkeys quickly learned who delivered the best value and quality. The monkeys even responded when people had “sales” going on.

Santos reports there was never any evidence of the monkeys “saving” their currency — much the way humans don’t.  There were even episodes of spontaneous “larceny,” in which monkeys would steal tokens from each other. Again, familiar territory for the human race. The monkeys were also presented risky propositions — in which they could opt for a consistent amount of food for their token, or take a chance with a salesperson offering varying amounts, which could be greater at times. The monkeys took irrational risks with their tokens.

The lesson for humans, Santos concludes, is that we will keep making the same mistakes over and over again — and we can’t help it:

“We’d like to think that the mistakes we make are really just the result of a couple bad apples or a couple really sort of FAIL Blog-worthy decisions. But it turns out… most of us, when put in certain contexts, will actually make very specific mistakes. The errors we make are actually predictable. We make them again and again….  think of our evolutionary predilection for eating sweet things, fatty things like cheesecake. You can’t just shut that off. You can’t just look at the dessert cart as say, ‘No, no, no. That looks disgusting to me.’”

Hmmm.  We didn’t learn too much from the Tulip Mania of 1637 or the real-estate crash of 1870, did we?

Santos holds out hope that we employ new systems or processes that help overcome these constantly repeated errors:

“Humans are not only smart; we’re really inspirationally smart to the rest of the animals in the biological kingdom…. We actually have all of these cases where we overcome our biological limitations through technology and other means, seemingly pretty easily. But we have to recognize that we have those limitations. …the irony is that it might only be in recognizing our limitations that we can really actually overcome them. The hope is that you all will think about your limitations, not necessarily as unovercomable, but to recognize them, accept them and then use the world of design to actually figure them out.”

RE: Are irrational economic choices baked into the human psyche?
Most people will say "if I had my life to live over again, I'd do (something financial) differently." I've told my wife (and she gets mad when I say it) that if we started over we would make all of the same mistakes again, because they weren't "mistakes" but, rather, poor decisions, and we knew they were poor decisions when we made them. Sure, there were lots of times when we denied ourselves, and we can look back on our lives and see all of the things other people have done that we haven't; but we also have done a lot of things we couldn't really afford, partly because we felt we had denied ourselves too often in the past.

I think I'll have that doughnut now.

Sorry, folks I don't see the problem. Now, what were those seven sins?

RE: Are irrational economic choices baked into the human psyche?
Santos is an idiot, if he really believes as this article claims. Monkeys are not rational, people are. People have the option of overruling this monkey-like behavior with the human mind, both quantitatively and qualitatively different from the monkey mind (http://plato.stanford.edu/entries/cognitive-science/).

If a cognitive science research wants to figure out why so few humans DO this with their minds, they have to start by clearing their own minds of such irrational assumptions as we see in this article.

It only takes a few rational people
From a macroeconomic perspective, it doesn't matter if most people are irrational. Irrational people just make market opportunities for rational people, and it doesn't take many rational people to make an irrational market rational.

Just look at what happened with the housing bubble. At the end a few rational people figured out the bubble and sold real estate short. They made a bundle helping the market become rational again. It's also forgotten that before the bubble burst a lot of people made big bucks as prices rose -- irrational people sometimes come out on top despite themselves.

If you're looking for an economic system where people are protected from their irrational choices, then it's not capitalism. Unfortunately, nobody has come up with an economic system that rewards people for making irrational choices that can survive in the long run. All capitalism can do is move resources to where they're the most productive, which tend to be the places where they're the most rationally used. It's primitive and sometimes brutal at its core, but it's the best we have.
