People's minds are TERRIBLE to handle some stuff, random events for instance. On the other hand we evolved to notice patterns so instinctively handle them pretty well. We're good at making generalizations when patterns are involved.
We don't need that most women we know act in a certain fashion to spot a pattern, not even 50%. Instinctively, a small sample will trigger our senses if we know the pattern we're looking for. Rationally, we need to make sure this sample is unbiased.

Now, a while ago I realized TRP's terror tales validated those instincts, but that's a remarkably biased sample, ALL women there are the worst of its kind. So I gave some thought and noticed I have enough examples to support my belief. Around 11% of the couples I know well enough have women whose behaviors are perfectly described by RP and cause their partners to be miserable.

How high is that number for you?
