Our brains evolved for a very different world than the one in which we are living. They evolved for a world in which people lived in very small groups, rarely met anybody who was terribly different from themselves, had rather short lives in which there were few choices and the highest priority was to eat and mate today.

Dan Gilbert is a professor of psychology at Harvard University. His research in social psychology about affective forecasting, emphasizing on cognitive biases (errors of judgment), has been worldwide recognized.


We are the only species on this planet that has ever held its own fate in its hands. We have no significant predators, we're the masters of our physical environment; the things that normally cause species to become extinct are no longer any threat to us...

And yet, the only thing -the only thing- that can destroy us and doom us are our own decisions -our limitation to make thoughtful decisions.

If we're not here in 10,000 years, it's going to be because we underestimated the odds of our future pains and overestimated the value of our present pleasures. We live in a complex world with many choices that require a sharp sense of discernment.

But this sense of discernment, because it is biased, will remain the greater obstacle to our desire as long as we don't recognize them and learn to overcome them.
