What lead to the self-contradiction

In the chapter “less is more”, the notion of conjunction fallacy reveals that people’s thinking structure is not logical and is easily being biased. From my perspective, the “less” refers to the information provided for an event, while “more” refers to the uncertainty of possibility and mental effort needed to draw a conclusion. People’s mind works much slower when processing abstract problems than dealing with those are concrete. Abstract problems, such as calculating possibility, is not suitable for people to think. Thus people tend to make them more crystallized such as analyzing them into selecting people in red clothes from the crowed, which is more understandable. When people confront with abstract questions, if they rely on intuition, they are more likely to make mistakes. That might could explain the one of the reason why people are self-contradicted in decision making. Compared with computers which are predetermined an overarching algorithm, people’s priority are changeable depending on present condition and scenario.

However, as the ultimate form of nationality, logic is just a tool. System one which basically depends on the intuition of mind, fits the needs of survive and the creature’s nature of “profit and avoid loss” of creature. It is faster, more effective but more likely to make wrong decision than lazy logical thinking. Intuition are suitable for events that we wouldn’t lose much if we make mistakes. The reason why people make decision off the top of one’s head is the wrong estimation of results and conceit of the decision maker.

It might be better if we do not make judgement when you don’t have enough evidence to support it. With limited clue provided, the possible assumption could be substantial, however, it means the possibility of making mistakes would be larger. It is noticeable in the decision making process. in most cases, we are usually under much urgency to draw out a conclusion and move on to the next step, employing information in mental account of system one. When deducting and making decisions, be on your guard, slow down and collect sufficient factual evidence. If people get impatient and try to speed things up, that will lead to self-contradiction when confronting similar cases.
