We unfortunately seem to be unconsciously biased against those in society who come out on the bottom. - Leonard Mlodinow

We afford automatic respect to superstar business moguls, politicians, and actors and to anyone flying around in a private jet, as if their accomplishments must reflect unique qualities not shared by those forced to eat commercial airline food. And we place too much confidence in the overly precise predictions of people - political pundits, financial experts, business consultants - who claim a track record demonstrating expertise.

It might seem daunting to think that effort and chance, as much as innate talent, are what counts. But I find it encouraging because, while our genetic makeup is out of our control, our degree of effort is up to us. And the effects of chance, too, can be controlled to the extent that by committing ourselves to repeated attempts, we can increase our odds of success.

The fact that human intuition is ill suited to situations involving uncertainty was known as early as the 1930's, when researchers noted that people could neither make up a sequence of numbers that passed mathematical tests for randomness nor recognize reliably whether a given string was randomly generated.
