We've all seen it all over the news in recent years (decades, for those of who've been around long enough) ... people who are originally pretty sure they're right about something, tend to "double-down" on their convictions in the face of convincing evidence to the contrary ... and then double-down again.

Admitting you're wrong about something important, when you were pretty sure you were right, is just effin' hard.

Anybody here used to think climate change was a crock? What changed your mind?
