But your beliefs are your posteriors, not your priors. If the only thing that's locked in is your priors, that's not a locking-in at all.
That's not obvious. You'd need to study many specific cases, and see if starting from different priors reliably predicts the final posteriors. There might be no way to "get there from here" for some priors.
When we speak of the values that an organism has, which are analogous to the priors an organism starts with, it's routine to speak of the role of the initial values as locking in a value system. Why do we treat these cases differently?
This is our monthly thread for collecting these little gems and pearls of wisdom, rationality-related quotes you've seen recently, or had stored in your quotesfile for ages, and which might be handy to link to in one of our discussions.
