The Human Nature Handbook
Like Duolingo, but for The Human Nature Handbook. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 9 levels across 2 sections, about 18 minutes end to end, roughly 4 days at five minutes a day. It moves through The Instinctive Self and The Rationalizing Mind. It starts from scratch.

Key ideas in The Human Nature Handbook
- The human brain prioritizes negative information as a survival mechanism
- The amygdala triggers the same physiological response for social ego threats as for physical danger
- Negative stimuli produce more brain activity than positive stimuli of the same intensity
- Physical symptoms like sweaty palms and racing heart are the body preparing to fight or flee
- Survival software treats social insults as threats to our standing in the 'tribe'
- Modern social stressors hijack ancient survival circuitry
- Negativity bias in social feedback
- Physical and social threats
- The brain consumes a massive amount of the body's energy and seeks to conserve it
- Humans are evolved to assume 'agency' or intent behind sounds to avoid being surprised by predators
- Habits allow the brain to shift from expensive 'deep thinking' to efficient 'automatic processing'
- Recognition of negativity bias in social feedback
- Novelty requires active monitoring which is metabolically taxing
- Pattern seeking helps us find order in chaos, even when none exists
- The brain prefers a false alarm (hearing a ghost) over a missed threat (ignoring a predator)
- The psychological pain of loss is roughly twice as powerful as the pleasure of gain
