I sometimes think that human beings are not meant to be rational in the long-term, and this is why democracy is good. Let me explain, get ready for some crazy hypothesizing... The premise is that the only thing we consistently do is manifest our personality. Personalities can be described quantitatively and they follow an approximate multi-dimensional normal distribution. Personalities shape how we see the world and in turn how we act. This means that, as a society, when faced with a challenge, we will respond on average as the average personality would respond. Every once in a while, novel challenges come and they are faced in a way that extreme personalities would act. We don't know in advance if this is the most effective personality to deal with the issue, but we have to try something new as the average personality won't do anymore. Thus we approach novel problems in a trial and error basis, with extreme personalities taking the charge. Since new members of the species are constantly being born, and random mutations in their genes, plus environment, assure that their personalities fall more or less randomly somewhere in the distribution of personalities, we can be assured that we will always have a very big supply of average personalities to tackle average problems, and a smaller supply of exceptional personalities to tackle exceptional and novel problems. Given the above paragraph, democracy is a way, in theory, to make all personalities heard, in the exact proportion in which they could be effective at dealing with problems.
