So Kramnik, being a chess player and not a statistician, invented various methods of "detecting" cheating which seemed convincing for for a layman but questionable mathematically. Then he started attacking Daniel, Hikaru and some other players online. This all led to pretty tragic consequences. Kramnik still believes that he's in the right. The only good thing out of this is numerous funny videos by chess players try…
A lot of people imagine chess players to he smart, but there's a video of asking grandmasters very simple (imho) general knowledge questions that they did absolutely abysmally at. It's probably safe to assume that someone who is really good at chess is actually bad at anything that isn't chess
From that point of view, you should really consider them to be as knowledgeable about these things as high school dropouts. It was hilarious following the whole cheating thing and seeing them try to interpret these statistical results and coming to really stupid conclusions.
You could say it’s difficult to see them this way due to the cultural and historical perspectives on chess but this is the reality of top grandmasters at this time.
