Like Duolingo, but for Everyday Psychology. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

Key ideas in Everyday Psychology
- Unsolicited gifts create a feeling of social indebtedness that people feel compelled to balance
- The urge to reciprocate is triggered even when the initial favor was never requested
- The return favor often ends up being larger than the original gift
- People judge value by comparison to a nearby reference point rather than in isolation
- Starting with an extreme baseline reframes a moderate option as a bargain or a compromise
- The actual value of the middle offer never changes, only how the mind anchors it
- Uncertainty triggers an instinctive assumption that the surrounding crowd knows the right action
- Observing others acts as a mental shortcut that bypasses deliberate personal analysis
- Social proof becomes most powerful when the observer is unfamiliar with the setting
- People instinctively push back when they feel their autonomy or freedom to choose is threatened
- Explicitly acknowledging their right to refuse removes the perceived pressure, eliminating the need to resist
- Disarming psychological resistance allows the listener to focus on the merit of the request itself
- People disproportionately stick with pre-selected options because switching takes cognitive effort
- Setting a default preserves full freedom of choice while leaning on natural human passivity
- Default effects vanish when users are forced to make an active, unassisted choice from scratch
- We attribute others' negative behavior to their personality or character flaws
