This is an aphorism that I think I made up today.
It is a derived from a longer one that also came to me today: the better your sociology, the more you trust strangers. This is because you have a better idea of which categories of people are dangerous.
I have been studying social trust, which I think is the crucial glue of the happy society. Fear is the enemy of the happy society.
More educated people are generally less fearful. I think this is because they have a more realistic sense of how likely any of the dangers they can imagine really are. They are also more likely to research potential dangers, rather than rely on gut instinct or fears promoted by others.
