The Happiness Hypothesis

IDEA 1
The rider and the elephant
The conscious mind is a rider on a powerful emotional elephant. Lasting change means training the elephant, not lecturing it.
IDEA 2
Reciprocity
Mutual exchange underpins relationships and cooperation. Use it to build trust, and beware those who exploit it.
IDEA 3
Happiness comes from between
It arises from the right relationships between you and others, your work, and something larger than yourself.

IDEA 1
Intuitions come first
Moral judgements are fast and emotional; reasoning mostly justifies them afterwards.
IDEA 2
Morality is more than harm and fairness
People also care about loyalty, authority, sanctity and liberty, in different mixes.
IDEA 3
Different politics, different foundations
Political groups weight these moral foundations differently, which is why debates feel like talking past each other.

IDEA 1
The great rewiring
Between roughly 2010 and 2015, adolescence moved from play-based to phone-based. Haidt links this shift to a sharp rise in teen anxiety, depression and self-harm.
IDEA 2
Overprotected offline, underprotected online
Children lost free, unsupervised play in the real world while gaining unlimited, unsupervised access to the online world.
IDEA 3
Four new norms
No smartphones before high school, no social media before 16, phone-free schools, and far more independence and free play in childhood.
