Low time alarm triggers blunders

An analysis of 68 million online games played on Lichess, published on GitHub by an unnamed Physics student, found that blunder rates, i.e. moves that drop your evaluation by 2 points, jump significantly at the moment when the low-on-time warning sounds, that is with 20 seconds to go in a 3 minute game, or with 60 seconds during a 10 minute game.
