即使决策的程序完全符合理性的原则，但是在过程中，我们很难避免落入某些思考陷阱当中。人脑不可能像电脑一样的精准以及百分之百的客观，每一个人都有既定的思考模式、偏见，对于资讯的解读也会有所偏差。换句话说，每个人在思考上都有某种程度的限制，只有意识到自己的不足，才能更谨慎的思考，降低错误发生的可能。 Even if the decision-making process is fully in line with the principle of reason, but in the process, it is hard to avoid falling into the trap of some thinking. The human brain can not be as precise as a computer and 100% objective. Everyone has an established mode of thinking and prejudice, and the interpretation of information may be biased. In other words, everyone has some degree of restriction in his thinking. Only when he is aware of his own deficiencies can he think more cautiously and reduce the possibility of mistakes.
