Via Overcoming Bias.
Doubting conventional wisdom seems pretty central to my style and central issues. So I took some time to ponder the general issue of doubt. Here’s what I came up with.
The relation between confident and doubtful states of belief is like that between the three corners of a triangle and the points within the area of the triangle. Even though there are far more area points than corner points, area points are more similar to each other, in a distance sense. In the same way, there are far more states of doubt than confidence, yet states of doubt are more similar to each other, in that they lead to similar decisions.
What can you do about serious skepticism, i.e., the possibility that you might be quite mistaken on a great many of your beliefs? For this, you might want to consider which of your beliefs are the most reliable, in order to try to lean more on those beliefs when fixing the rest of your beliefs. But note that this suggests there is no general answer to what to do about doubt – the answer must depend on what you think are actually your most reliable beliefs.
