People Aren't Rational

It's something the Ivory Madonna constatntly has to remind herself...people aren't rational.

Take religious believers (please!) We keep wanting them to make sense. We say things like, "According to your own beliefs, if you are against abortion then you should also be agaisnt the death penalty" or "Your own scriptures tell you that all unbelievers should be put to death, how can you believe that?"

It doesn't work that way. Religious belief isn't consistent and doesn't make sense. Religious believers don't study their scripture and beliefs in order to decide their opinions -- they form their opinions first, then cherry-pick among their scriptures and beliefs to justify those opinions. Anything in the scripture or the beliefs that contradicts their opinions...they just ignore. Or rationalize away.

Take free market forces. We keep wanting to assume that people will make rational decisions in the free market...and that over time, the decisions people make will lead to a better life for all.

It doesn't work that way. Unleaded gasoline is a great example. A few decades ago, lead poisoning was epidemic among children, largely due to lead in gasoline. Unleaded gasoline was safer, but more expensive. But is was clear that we would all be better off if we moved to unleaded gasoline.

Did consumers make the rational decision, and buy unleaded gas even though it cost more? Did market forces drive leaded gasoline away?

You know it didn't happen that way. Government regulation forced leaded gasoline off the market. If we'd relied on market forces to do the job, leaded gas would still be everywhere, and we'd be into the second or third generation of brain-damaged adults. (Hmmm...has anyone investigated lead exposure and the Bush family?)

Yes, individual people can behave rationally and make rational decisions, and should be encouraged to do so. But it's not our default state -- and we should stop assuming it is.
