Only children believe in reasoning; adults only argue when it benefits them, and abandon reason when it doesn’t.

Feminism does a great job in this regard, focusing only on what benefits itself.

How do you gain others' trust and support to secure a better position in human society? Look at US presidents—why do election promises usually only get half fulfilled after taking office? They don't fulfill everything, nor do they break every promise. Why? Because it's been mathematically calculated.

Humans naturally trust language more than actions. This is the biggest difference between Homo sapiens and Neanderthals—a trait inherent to our species. As Liu Cixin put it, humanity's greatest advantage is the ability to lie.

In real life, people who can't see the bigger picture just埋头 (bury themselves in work). People who understand the game make promises with their mouths. Sweet-talkers, those who give others positive linguistic experiences, are the ones who get more resources.

Those who are tough-talking but soft-hearted suffer the most. But is being endlessly sweet-talking useful? No. If you make three consecutive promises and don't fulfill any of them, people's trust in you drops to zero, and you're never going to recover.

So through calculation, humanity learned that promising twice and delivering once—like managing a credit card—is the optimal model for building credit. You can't not borrow, and you can't borrow without repaying. Only by borrowing and repaying can you improve your credit score. That's why every US president, almost synchronously, fulfills exactly half of their promises, operating right at the actuary's data line. See that? Each one is sharper than the last. Creating a stable, reliable impression for others, fully exploiting human nature's weaknesses, cultivating trust and shaping expectations—all of this has been statistically analyzed and refined into actuarial skill.
