Pretty much anything related to statistics and probability. People have gut feelings because our minds are really good at finding patterns, but we’re also really good at making up patterns that don’t exist.

The one people probably have most experience with is the gambler’s fallacy. After losing more than expected, people think they’ll now be more likely to win.

I also like the Monty Hall problem and the birthday problem.

A lot of outdoor survival “common sense” can get you killed:

Moss doesn’t exclusively grow on the north side of trees. Local conditions are too chaotic and affect what side is most conducive to moss. Don’t use moss for navigation.

Don’t drink alcohol to warm yourself up. It feels warm but actually does the opposite: alcohol opens up your capillaries and allows more heat to escape through your skin, which means you lose body heat a lot faster.

Don’t eat snow to rehydrate yourself. It will only make you freeze to death faster. Melt the snow outside of your body first.

Don’t assume a berry is safe to eat just because you see birds eating them. You’re not a bird. Your digestive system is very different from a bird’s digestive system.

If you’ve been starving for a long time, don’t gorge yourself at the first opportunity when you get back to civilization. You can get refeeding syndrome which can kill you. It’s best to go to the hospital where you can be monitored and have nutrients slowly reintroduced in a way that won’t upset the precarious balance your body has found itself in.

The immune system is strong and defends your body against germs.

The immune system works 100% of 50% of the time. Immunology is the best way to convince someone that it’s a miracle that they’re still alive. Anyways, get vaccinated. Don’t rely on your immune system to figure things out
