Controlling public opinion has a tried-and-true tactic—repeated brainwashing. The human brain has a weakness: it tends to equate familiarity with credibility, making it hard to distinguish how many times you've heard something from whether it's actually true. This tactic is skillfully employed by authoritative institutions and various marketing experts.

Interestingly, psychological research has also uncovered an even more ruthless trick: you don't need to repeat the full information. Just say half or certain segments, and people will still fall for it.

Think about how projects in the crypto space package their concepts—repeatedly emphasizing a few key selling points. Even without a complete logical chain, investors are easily led by the nose. That's why projects with better marketing often thrive more than technically solid ones. Recognizing this allows you to maintain a clearer judgment when encountering various voices.
