postjudice

noun /ˈpəʊstdʒʊdɪs/

A prejudice or bias acquired after the fact, or after a given event.

There is a mixture of good sense and of what, for want of a better name, people call prejudice: but to this mixture we owe our stability. The proper word is postjudice, a clinging to past experience, often longer than is held judicious by after times.
