There is nothing in the education of the average non-scientific human being to discourage him from the habit of generalizing from little or no evidence, and worse still and far more important, nothing to discourage him from the habit of starting with a generalization and ending up with the individual, instead of the other way round.
there are people who are born superficial ... They prefer not to have to deal with more than a limited number of oversimplified ideas - they prefer the book reviews to the books, the headlines and the leading paragraph to the full report, the generalization to the facts, and the negative to the positive.
for every person who's stepped out of line and lived to regret it, there are two people who stayed in line because they got their values mixed and lost their nerve, and who have lived to regret it still more. You don't hear about those people because they're still in line where they don't show.
