You have the right to change your mind.
Genius is a dynamic entity and while some truths once arrived at are final, many aren’t and you’re never going to be absolutely sure which ones are which.
If you find that your view point isn’t changing, (keeping a journal is a great way to watch for this) then you might have a problem.
If you’re not at least a little embarrassed by some of the things you’ve written in the past then you’re probably not growing intellectually.
Don’t be completely ashamed of these things, and don’t be afraid to say you were wrong or you at least feel differently now.
We each make our decisions based on what we know at the time, and a fact of existence is that what you know, changes.
Don’t go back and make corrections, for one thing it’ll just draw attention, simply make your new position clear somewhere else and if asked directly, be honest.
If they want to try and shame you, let them, the both of you know how insane it is to try and scold someone for adapting, and if they don’t, well then their opinion is not worth caring about.
Just sharing 🙂
