Everyday Psychology
Discover why you make irrational choices, misremember yesterday's events, and copy the crowd. Learn the core principles behind daily human behavior through relatable, real-world examples.
Like Duolingo, but for Everyday Psychology. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Decoding Your Choices and Memories and Navigating Social Dynamics. It starts from scratch.

Key ideas in Everyday Psychology
- Thinking carefully through every single choice burns immense mental energy
- Heuristics act as cognitive shortcuts that trade perfect accuracy for speed
- Routine daily choices rely on 'good enough' decisions rather than deep analysis
- The first number you see establishes an anchor that frames every following comparison
- Seeing a high starting price makes any lower follow-up price look cheap, regardless of the jacket's true worth
- Anchoring occurs automatically before you can consciously evaluate reasonable value
- The mind estimates how likely something is based on how vividly or easily memories of it come to mind
- Rare, dramatic events like plane crashes make vivid memories that feel frequent and urgent
- Common, routine dangers like car accidents feel less threatening because they lack dramatic emotional recall
- The mind eagerly spots and remembers events that confirm an existing theory
- Evidence that contradicts your belief gets ignored, dismissed as a fluke, or forgotten
- Confirmation bias operates by filtering what you pay attention to in real time
- The psychological pain of a loss feels roughly twice as powerful as the pleasure of an equivalent gain
- Loss aversion makes people avoid fair 50/50 bets unless the potential reward substantially outweighs the risk
- Losing what you already hold triggers an immediate protective, emotional reaction
- Memory pieces together fragments of the past anew each time you recall them
