Adding to that, there's a lot of sampling bias as well. If a function fits my mental model of it, then I'm unlikely to revisit it. If a function doesn't fit my mental model, then it is very likely that I'll misuse it, increasing the likelihood of a bug, and increasing the likelihood that I re-read the code.
