Book explores how social contexts significantly shape our behaviors. Author argues that while society regulates behaviors causing physical harm, it’s slower to discourage harmful social environments. He attributes this to the belief in individual responsibility but suggests it’s compatible with policies promoting supportive environments. He notes that harmful behaviors becoming common make it less likely for parents’ hopes for their children to be realized. Despite the difficulty in measuring such impacts, the author advocates for simple policy measures to foster better social environments. Provided by publisher.
