- Monkeys also believe in winning streaks
In the first study in non-human primates of belief in winning streaks, researchers find that monkeys also share our unfounded belief in winning and losing streaks. The penchant to see patterns that actually don’t exist may be inherited—an evolutionary adaptation that may have provided our ancestors a selective advantage when foraging for food in the wild.
