How do people construct priors? Is it worth trying to figure out how to construct better priors?

How do people construct priors?

They make stuff up, mostly, from what I see here. Some even pretend that "epsilon" is a valid prior.

Is it worth trying to figure out how to construct better priors?

Definitely. Gwern recommends the prediction book as a practice to measure and improve your calibration.
