Data Mining Reveals the Crucial Factors That Determine When People Make Blunders

This study focuses on chess. The fascinating discovery is that in chess there are certain "skill anomalous positions" where a player ratee 1800+ is more likely to make a blunder than a player rated 1200 to 1800.

Here are the positions taken from the research. In the first three, the GM is less likely to make a blunder that players rated lower than the GM going down to 1200 elo. The final three are the skill anomalous positions in which GM made blunders more frequently than lower elo rated opponents. 8/1k6/8/1PK5/8/8/8/8−0 2k5/8/1K6/2P5/8/8/8/8−1 1k6/8/K7/1P6/8/8/8/8−1 GMs blunder more in these 2k5/8/1P6/2K5/8/8/8/8−1 1k6/8/2P5/1K6/8/8/8/8−1 7k/8/6P1/6K1/8/8/8/8−1 Have fun.
