The video discusses four mental games that can be difficult to get out of your head.
1. "The Game": A mental game where the goal is not to think about it. If you remember it, you lose. The game is a paradoxical situation that can become obsessive for some people.
2. "The Reddit Button": A social experiment where a button was created on Reddit with a one-minute countdown. If the button was not pressed, it would reach zero. Over a million people participated, and the game became addictive.
3. "The Mirror Game" or "The Mirror Experiment": A game where you stare at your reflection in a mirror with dim lighting for five minutes. You may start to notice that your reflection looks different, and you may experience hallucinations or a sense of fear.
4. "Linda's Problem": A classic probability puzzle that deceives logic. The puzzle asks which is more likely: Linda working in a bank or Linda working in a bank and being an activist for women's rights. The correct answer is the first option, as it is more likely for Linda to work in a bank than to work in a bank and be an activist.
These mental games can be thought-provoking and challenging, and they can help us understand how our minds work.
