Although it is easier to find information these days, it is easier than ever before to find misinformation, pseudo-facts, unsupported and fringe opinions, and the like. Children should be taught at an early age what constitutes evidence, how to detect biases or distortions in newspaper accounts, and that there exist hierarchies of information sources. In the medical field, for example, a controlled experiment published in a peer-reviewed journal is a better source than a blog by the Ginseng Growers Association, promoting the health benefits of their own product.

Daniel LevitinThe emerging picture from such studies is that ten thousand hours of practice is required to achieve the level of mastery associated with being a world-class expert - in anything. In study after study, of composers, basketball players, fiction writers, ice skaters, concert pianists, chess players, master criminals, and what have you, this number comes up again and againโฆno one has yet found a case in which true world-class expertise was accomplished in less time. It seems that it takes the brain this long to assimilate all that it needs to know to achieve true mastery.
Daniel LevitinDecision-making is difficult because, by its nature, it involves uncertainty. If there was no uncertainty, decisions would be easy! The uncertainty exists because we don't know the future, we don't know if the decision we make will lead to the best possible outcome. Cognitive science has taught us that relying on our gut or intuition often leads to bad decisions, particularly in cases where statistical information is available. Our guts and our brains didn't evolve to deal with probabilistic thinking.
