I don’t think there’s some process to follow to acquire knowledge with a guarantee that we haven’t made a mistake, but I don’t think that means it’s impossible to acquire knowledge. I think we can and do acquire knowledge about people’s beliefs and intentions and use that knowledge to solve problems. Obviously examples are convicting people of fraud and various crimes where the person’s intentions are relevant.

This gets more complex in the realm of, let's call it politics, where the quest for knowledge may be adversarial, and is played over long periods. With fraud and crimes of intent, you often have very clear evidence where the person was unguarded (they said a slur as they committed the crime, making it a hate crime, for example).

I'm not saying reliably discovering intentions is always impossible. I'm saying that it is not always possible.
