Inconsistencies of opinion, arising from changes of circumstances, are often justifiable.

Holding the same position after the situation has changed is not integrity, it is inattention. A view is a response to a set of conditions, and when the conditions move the honest response moves too. This needs saying because people are punished harder for changing than for being wrong, so the safe course is defending a position you no longer hold. That is an expensive sort of consistency.

When you shift, say plainly what changed and why, so it reads as reasoning rather than drift. Give other people the same room when they do it. What you want is a record of good thinking, not a record of never moving.
