This works as a beginning to explaining this group of ideas. I like the focus on passed-down-change, but I want us to do more to exactly pick out what we mean here. It's especially important to note:

1. A brain wrong-going (bias) is different from many other kinds of problems and troubles your brain can have.
2. A brain wrong-going is sometimes about doing what you want, rather than about knowing what's true.
3. And the idea of a brain wrong-going can't be explained without also explaining the idea of a brain short-cut (heuristic).
