> if acting on one datum was always fallacious, you'd think > it would be bred out of us by now. I think that we're set up to predict and act on N data points, and sometimes N happens to be one. The point of the article, to me, was that you have to understand this behavior in yourself and watch out for fallacies. Just as if you know about confirmation bias, so you keep an eye out for contradictory evidence, if you know about the statistical problem of generalizing from one you can watch out for that, too.
