“Meteor” by Dan Brown (could be a different name in the original language). It was the first time I read something that was bad. Up until then book were cool and fun and interesting. It was a puzzling experience.

Edit: it’s called “Deception Point” in the original.

I really would like to see some studies on that topic “does cognitive decline skew your position to the right”. If it does it’s usually slowly over many years. But fetterman had a huge decline suddenly and basically in love with genocide now. (I still believe he didn’t think like that before).

Would make sense in a way - stripping away all nuance from the world by means of deteriorating perception makes people only see good and bad or my team / their team.
