Term Search: Iago Moment

There are many concepts that are clear to my way of thinking that - as far as I know - have not entered into our general language. My vocabulary is large and I have multiple degrees and yet I feel that these ideas have not been given social expression via a word or phrase. So I'm going to use this blog to flesh these ideas out. If anyone knows a term for these ideas, please comment below.

The Iago Moment: when a new piece of data changes your previous understanding to the exact opposite conclusion.

This is based on the game 'Othello' which has black pieces that will switch to white, and vice-versa, when bookended by that color. This is the closest item in my culture and experience that depicts the time of idea switching inherent in the concept. A row of black pieces, when you add one more datum, all turns to white.

The name 'Othello' comes from the Shakespeare play and since it's a game of black-and-white pieces, and the title character's race (African) is instrumental to the plot, I understand why the game was named that. But it still feels racist to me. Iago, on the other hand, is the play's antagonist, so I might as well keep the game & name but evade the overt racial message.
