What about someone raised in a bizarre alternate universe where tradition, culture and religious belief dictate that those who go faster than 30km/h while sober or in bindings have their souls eaten by demons, so everyone has to drive blind drunk without a seatbelt?
How could such a world possibly exist for more then a couple of years without people noticing that there is a problem?
I'm quite confident it wouldn't, hence "bizarre", but I don't think that matters to the questions I'm actually trying to address with the hypothetical. I just used a drunk driver because that's what DeVliegendeHollander used.
I realize this question is contrived, but I figure it might provoke some fun discussion, so here goes:
If you could push a button and have your brain modified to precisely remove a cognitive bias (and have no other unnecessary effects—most convenient possible world), which would you choose? Why?
What if you were choosing for the whole human race?
