An example of confirmation bias?
Late just this November, the world champion chess player Vladimir Kramnik played the leading chess software, Deep Fritz. In his second match, he allowed the computer to win with a mate in one. He said,
It was actually not only about the last move. I was calculating this line very long in advance, and then recalculating. It was very strange, some kind of blackout. I was feeling well, I was playing well, I think I was pretty much better. I calculated the line many, many times, rechecking myself. I already calculated this line when I played 29…Qa7, and after each move I was recalculating, again, and again, and finally I blundered mate in one.
Is this confirmation bias? Looking for evidence that the line he was calculating was the correct line, but not looking for evidence that it was the incorrect line? If so, it means that, the best current player of chess in the world has not been able to completely rid himself of this bias, even in the limited field of his area of expertise.
