1/ The human brain is an imperfect machine. There are some common illusions and cognitive traps that advertisers, marketers and propagandists (and occasionally speechwriters 😉) will use to persuade you of things.
Here are a few common ones👇
2/ SOCIAL PROOF: when you are presented with a "consensus" on an idea, you are more likely to believe that the idea. E.g. when a political party shares polls showing that they're in the lead 📊
3/ RECIPROCITY: you are wired to respond to a positive action with another positive action (like becoming more cooperative or friendly). E.g. when a shop offers you a "free taste" to lure you into an aggressive sales pitch.
