One of the realms of scientific decision-making is to separate decision-making ability from luck. Suppose there are two options in front of you: choose A, the success rate is 65%; choose B, the success rate is only 35%. The scientific decision is to resolutely choose A. If you choose A and find that the result is B, can you say that you should not have chosen A? What poker players can do is to choose the option with a high probability of winning. As for the failure of the result, it is just a matter of luck. A clear-headed person must be able to distinguish between decision-making and luck.

People always think that if the result is not good, there must be a better decision at the beginning - but if you play poker frequently, you will know that this is not the case at all. Poker players call this situation "result-oriented". Poker is played many times, and what you care about is a scientific decision-making system that can win money with a high probability, rather than the win or loss of a certain hand. It's like running a casino. What you want is to win money in the long run. If you change the decision-making system at will because of the loss, this is "result-oriented", which is equivalent to having no system. Ordinary people focus on results, and experts focus on systems. This is the basic skill of scientific decision-making.

Duke once served as a commentator for amateur players. One time, he told the audience that in the current situation, the probability of player A winning was 76%, and the probability of player B winning was 24%. In the end, player B won. At that time, a spectator said that you made a wrong prediction. Duke replied that it was not a wrong prediction. He had already said that player B had a 24% chance of winning. Now that player B won, it was just that the event with a probability of 24% had happened.

You must be able to distinguish between bad luck and wrong decision. You cannot judge a person by his success or failure. You should focus on the level of decision-making and the rationality of the decision-making process, rather than the final result. Many people like to say that they "don't care about winning or losing". In most cases, this is just bragging. They don't know what "don't care about winning or losing" means. They may just want to say that they have a strong psychological endurance.
