One of the things that chess helps develop is an ability to falsify your own ideas. This may seem strange to the general public who usually try to win their argument via any means available. But it is a very valuable skill that has applications in many different fields, the most obvious one being scientific research.
Does this mean that scientists will also be good falsifiers given that their profession should demand it? Not necessarily, and it might even be in a researcher’s interest to deliver a promising study in order to secure funding. Of course there is a process of peer review of published papers which should in theory lead to errors being detected. Yet I can’t help but think that the incentives to do so are far less clear and direct than on the chess board.
Here anyway is a funny clip of an old man playing against himself. He tries very hard to play both sides with amusing consequences.
