1, ``brain motionEmits a command signal of
2, "OwnwillI'm going to move my finger with
3, "actually finger movement"

Generally, it seems that it will be done in the order of 2, 1, and 3, but the experimental results are as above. The motion command signal occurred 0.35 seconds before the subject's decision-making time. This problemBrain scientistThere was a great controversy between the two. If the experimental results are taken in a straightforward manner, "free will" is denied, but if the subject's decision-making first occurred and brain activity was triggered by it, the first decision-making occurred in a place other than the brain. Then, separated from the brain, "精神"Or"HeartExistence (dualism) Has to be assumed, which is unacceptable in traditional science.

Osaka UniversityProfessor Rivet has obtained many similar results in addition to Professor Rivet's experiment, and decision-makingConsciousnessBefore going up to無意識It can be considered to be conscious after being decided by. Consciousness does not control human behaviors and thoughts, but rather they are performed in the unconscious area, and consciousness is a check mechanism for grasping the situation, thoughts, and behaviors of one's own.

Various models have been created to capture decision making. There are a decision process model that models the decision itself and a decision support model (system) or analysis model that supports the decision.

Among the decision-making process models, there is one that is especially famous. It is a model that considers people, problems, and solutions as garbage, and puts the garbage in a "decision-making opportunity" that looks like a trash can, and when the decision-making opportunity is full, a result is obtained. Its characteristic is that it is premised on the idea that "human beings cannot make rational decision making" instead of "rational decision making" based on the past model.

Support model

The decision support model includesDecision tree (Decision Tree), OR (Operations Research),AHP,Game theoryThere is.

The support model mainly supports decision making by quantifying the value of evaluation criteria and alternatives.
