This is the true meaning and practice of "tit for tat" in life

We have heard the saying "a tooth for a tooth, an eye for an eye", which means that we should treat others as others treat us. This statement was denied by the non-preaching people: No matter what others do, we must always adhere to our own principles, adhere to our own beauty, and treat the world with kindness.

I don’t know if everyone is rolling their eyes and rolling their eyes after listening to these contents, or do they really feel that they should be a kind person "I want to be a better person in the world"?

I was reading something about game theory recently, and there is a long-term game principle called Tit-for-Tat Strategy. What it means is that goodwill comes first and never betrays first; then you can imitate the other party depending on the situation. That is, if you treat me well, I will treat you well. If you treat me badly once, I will treat you badly next time. But if you are nice to me next time, then I will be nice to you again. In short, I will directly copy what you did last time.

In other words, I will start to show kindness, but I will no longer be a "good guy". I will tell you through my actions that I am not bad, but I am not someone you can bully easily. If you want me to always be nice to you, you should always be nice to me.

If you think about it carefully, this method is really good. We have our own principles, but we will also protect our own interests. Because once some people take advantage of us and find that we won't resist, it will bring out the bad side of their humanity.

The approach we take is, in a sense, to help people be kind to others even if it is for their own benefit.

What do you think of this approach?
