sleep
Sleeping on it improves your problem-solving abilities.
A 2004 study found that participants who slept were significantly more likely to gain insight into a hidden mathematical rule than those who remained awake.
Participants who slept were approximately twice as likely to gain insight compared to those who stayed awake, rather than the sleep-deprived being specifically '50% less likely'.
The solution you need is likely already in your head, waiting for sleep.
Where this comes from
- Study
- Wagner et al., 2004, Nature
- What the check found
- Wagner et al. (2004) demonstrates that sleep promotes insight, not merely puzzle-solving. The '50%' figure is a rough summary that does not accurately reflect the study's reported improvement rates.
- Confidence
- Solid, with limits
