What are some examples of 'common sense' which are nonsense?
Wikipedia defines common sense as "knowledge, judgement, and taste which is more or less universal and which is held more or less without reflection or argument"
Try to avoid using this topic to express niche or unpopular opinions (they're a dime a dozen) but instead consider provable intuitive facts.
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.

that putting the thermostat up higher will heat the house up quicker (edit: I have in mind a bog standard UK home thermostat)
-
that sugary sweets make kids act "hyper"
-
that the moon's apparent size is due to how close it is to earth (same for seasons and the sun)
-
that your base metabolic rate slows as you age and is primarily responsible for you putting weight on in middle age
-
To tilt your head back if you have a blood nose.
This is no longer recommended advice, because you end up drinking the blood which causes vomiting.
- Probably initially said by someone concerned about their carpet.
Way to stop them is put ice over the back of neck, plug nose with tissue and clear clots each 2 mins.
The most vulnerable will be hit the hardest.
- Countries are rich because they have free markets.
- Tariffs are a good thing and competition is for losers.
- No one deserves a handout, as money should be earned.
- Large companies deserve a giant economic stimilus, because if we don't, our economy will crash.
- Being spied upon by your government or foreign governments whom I worship is okay, because I've got nothing to hide.
- Outsiders that sells goods that can be used to spy obviously and should be barred from all markets forever because they'll definitely spy on you and spying is wrong.
- If you feel threatened by another country, a pre-emptive strike should be allowed.
- You don't mess with the sovereignty of a nation. It's sacred and should be left intact.
- Police should always be allowed to use overwhelming force and their actions should be lauded
- You should have the right to protect yourself using firearms against tyranny as governments in general are never to be trusted.
"Bigger is better"
Common sense isn't just "not so common," it is a fundamentally broken concept at its core and a crutch that people use to hoist themselves above others they feel they are better than.
I view it as a thought terminating cliché people use when they're too lazy ti fully explain themselves. It can be useful for things that are truly obvious, like if you try touching something fresh out of the stove without protection you'll get burned, it doesn't really add anything to bother explaining it.
we need more working powers to keep our wealth and our standard of living up. obviously, as things are crumbling around us, this means we don't put in enough effort to maintain things, and more hands would help.
that is a false thought. The labor market is regulated by supply and demand. That means, fewer workers lead to higher wages and a higher quality of life. It might seem paradoxical, but having a smaller workforce means people in the country will be able to afford more stuff.
That is especially important as people discuss the birth-rate, and immigration, in all countries, also in the US and in Europe. People say things such as "women have 1.6 children on average, which means our population is declining, and obviously that is the reason why our quality-of-life seems to be going down as well". However, the opposite is true. As automation takes over and well-paying (and meaningful) jobs are eroded, having fewer people around doing all the work actually drives wages up, and leads to an improved quality-of-life.
