Twenty psychological effects of understanding "human nature"

You should not have the intention to harm others, but you must be on guard against others.
You can choose not to do it, but you can’t fail to understand what people say or understand their hearts.

1. Sunk cost psychology,
90% of women, even if they know their men are scumbags, still can't bear to break up. It's not because they love the man so much, but because they have given too much and are unwilling to let go.
The higher the price you pay, the harder it is to exit.
2. Murphy's Law.
When you worry about a negative thing happening, it tends to happen.
3. Face effect
When you make a big request and the other party refuses, and then you make a small request, the other party will basically be embarrassed to refuse again.
4. Curiosity Effect
If you like someone of the opposite sex and want him to have a good impression of you, the best way is to remain mysterious and calm. This way, he will become curious about you. If you keep licking him in a humbly manner, it will make people disgusted.
5. Broken Window Effect
In a very clean place, people are embarrassed to throw garbage, but once there is garbage on the ground, people will throw garbage without hesitation. Any small thing, if you don't try to stop it at the beginning, it will be difficult to change once it becomes a trend.
6. Inverse Proportion Law
He loves you most when you don't love him.
7. The door-in-the-door effect
Once someone accepts a small request from you, they are more likely to accept a bigger request from you.
8. Birdcage Effect
The more you have, the less satisfied you are. When you have a new item, you will definitely configure it with something that matches it, for example, if you buy a pair of shoes, you will buy a set of clothes to match it.
9. Forbidden Fruit Effect
In life, the more you try to hide a flaw, the more others will pay attention to it, such as a receding hairline.
10. Rosenthal Effect
If you are an introvert, you are more likely to be socially anxious.
Then the best solution is to label yourself as an extrovert when introducing yourself to a stranger for the first time, because human behavior will be controlled by consciousness.
11. 12-second effect
People only have 12 seconds to get angry about something. After these 12 seconds, they will return to their usual calm. Unfortunately, most people are controlled by these 12 seconds.
Do something you regret
12. Pandora Effect
There is a kind of rebellious psychology in human nature that the more it is forbidden, the more it will be allowed.
The more you don't let me see, the more I want to see
13. The Franklin Effect
Those you have helped may not necessarily repay you.
But those who have helped you,
They will often be more willing to help you again.
14. The cup effect
If you like someone, ask him out for a cup of milk tea and keep shortening the distance between the two cups while talking. If he doesn't react, it's likely that he likes you too. If he moves the cup away, it means he is on guard.
15. Suspension Bridge Effect
If you have a crush on someone, you can take her to a certain place and tell her that this is our secret base. This will quickly shorten the emotional distance between you and her and make her pay more attention to this relationship.
16. Recency Effect
When a group of people are reporting on their work, the last person to speak is often more likely to be convinced, which is why leaders always speak last.
17. Generative Effect
Learning existing things is far less fast than learning through actual operations. Only when you have actually operated it yourself can you truly know how to do it.
18. Peak-End Rule
If a person does 99 good things but only one bad thing, he is a bad person. On the contrary, if he does 99 bad things but only one good thing, others will regard him as a good person!
19. Hippocampus Effect
In daily life, we often meet someone and feel as if we have seen him/her somewhere before, or pass by a place and feel as if we have been there before. This feeling of déjà vu may be that your brain has called up a movie or novel you have watched before and feels so familiar with it.
20. Sour Grapes Effect
The more inferior a person is, the more he wants to see others make a fool of themselves. The more he flatters the strong, the more irritable and angry he is with the weak. For example, the less successful a man is outside, the more likely he is to be a bully at home.
