In 1967, Martin Seligman and Steven Maier showed that dogs given unavoidable shocks later stopped trying to escape, even when they could. “Learned helplessness” became a famous model of depression. Nearly fifty years on, the same researchers flipped their theory using neuroscience: passivity is the default response to prolonged stress. What gets learned is control, which lets the prefrontal cortex switch that response off.
Remembering is not replaying a recording — it is rebuilding. Each time you recall a memory, it becomes temporarily malleable and can be altered before being stored again. That is why two people can sincerely remember the same event… differently.
In 2003, Johnson and Goldstein compared European countries. Where you must tick a box to become a donor, consent rates ranged from 4% to 28%. Where you're a donor by default unless you opt out, they topped 85%. People aren't more generous on one side; most simply stick with whatever option was chosen for them.
