What is high cognition?

Independent thinking - rational thought - strong logical reasoning - not blindly trusting others.

What kind of people are more easily brainwashed by charlatans?

Lack of opinions and judgment - inability to think independently - too lazy to use their brains - eager to take shortcuts! This type of person is usually a microcosm of those easily brainwashed; in school, they copied homework until they became academic failures, and after entering society, they still can't shake off those poor thinking habits. Of course, there are also many experts in the community, like Value Brother who ranks in the top 1% in returns. He proves himself with real ability, unlike those charlatans who hide their return rankings and even give themselves a title like @Tutu's Legend of Deification, which is utterly laughable. Let me give you another example. On February 27th, he was still telling people to buy, but then war broke out, followed by continuous sharp declines. He then told people to cut their losses at low prices, and after they sold, Hong Kong stocks experienced a rebound, which he conveniently never mentioned.
