Everyday Behavioral Psychology
Bridge the gap between psychological theory and everyday human behavior. Learn how to design effective environments, diagnose motivational breakdowns, and sidestep common pop-psychology fallacies in personal and professional life.
Like Duolingo, but for Everyday Behavioral 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 Applying Behavioral Mechanics and Correcting Perceptual and Diagnostic Errors. It assumes you already know the basics.

Key ideas in Everyday Behavioral Psychology
- Small physical steps create micro-friction that depletes self-regulatory effort
- Removing even a single tap or login step changes behavior far more than persuasive appeals
- Habit adherence drops sharply when users must navigate multiple UI layers
- Paternalistic defaults trigger psychological reactance by threatening perceived freedom
- Reactance drives individuals to actively reassert control by defying the suggested default
- Defaults work best when transparent and framed as an effortless choice rather than a mandate
- Present bias makes people heavily discount future consequences like regret or distant health
- Hyperbolic discounting causes abstract future goals to lose to immediate temptations
- Pre-commitments succeed by attaching immediate friction, social exposure, or financial loss
- Salience decays as sensory habituation turns static visual cues into ignored background noise
- Novelty and positional variation disrupt cognitive filtering and re-trigger conscious attention
- Increasing text urgency fails if visual processing has already filtered out the cue container
- Physical affordances shape behavior by mechanically enabling or blocking actions in the environment
- Informational prompts depend on conscious deliberation, which fails under high cognitive load
- Altering environmental geometry changes action possibilities without relying on cognitive recall
- Expected extrinsic rewards shift the perceived locus of causality from internal interest to external payoff.
