Researchers at the University of Waterloo gave students lists of simple words like “apple.” Some had 40 seconds to draw each one; others wrote it out repeatedly. In a surprise test, drawn words were recalled roughly twice as often. Artistic skill didn't matter at all: even crude doodles did the trick.
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%.
