I used to be adamant that free will was real, without knowing precisely what I meant by that. Between some posts and comments, I became convinced that what I was thinking of as free will was somewhat trivial and that what I might call "correct decisions" was more like what I believed in. But correct decisions might be quite repeatable, certainly they would tend that way. So if the relevant decisions made by my mind are predictable, calculable, and only trivial decisions like "pick a number from 1 to 100" would be the ones that were most difficult to predict, then free will is not such a thing as I had adamantly previously thought.

I think the change came about more through discussions in comments than from posts themselves.
