Why can't people strangle themselves?

No, because the human body has a self-protection mechanism. Self-protection mechanisms generally work unconsciously. When the stability of self-concept is threatened, people sometimes take self-protection measures to deal with it. In real life, there are many situations that lead to self-protection (such as exposure to negative self-related information).

Individuals do not deal with memory neglect or self-immunity, but deal with these threatening information to self-concept truly and accurately. For example, when teachers face some constructive criticisms of their teaching ability, they often remember these criticisms and attach great importance to them. These scenarios need to be paid attention to in future research.

At present, a better explanation for this phenomenon is that people are more willing to pay attention to this information when its follow-up effect is greater than the harm caused by its potential threat. For example, teaching ability should be a plastic feature, so paying attention to this constructive and critical feedback can better promote oneself to improve teaching ability through efforts.

Extended data

First, psychological self-protection mechanism.

Psychological self-protection mechanism exists in people's psychological activities, and its function is similar to physiological immune system. When people are about to or have fallen into a state of tension and anxiety for some reason, they can use psychological self-protection mechanism to alleviate or avoid their inner anxiety and pain, so as to better adapt to life.

Common self-protection mechanisms include latent inhibition, rationalization (decoration), imitation, projection, reverse action, somatization, substitution, fantasy, compensation and sublimation.

Second, the biological isolation mechanism

In the long process of biological evolution, species have produced a self-protection mechanism of reproduction through natural selection, which is called "biological isolation mechanism". This isolation mechanism is mainly to maintain the relative stability of species.

Different species, such as dogs and rabbits, cannot produce energetic offspring if they have reproductive mating. Only when they have reproductive mating between the same or very similar species can they produce energetic offspring.
