“Common sense” is a colloquial term for knowledge that should be obvious.

Don’t sleep on the train tracks.

Don’t tease a bull.

Don’t drink toilet bowl cleaner.

Things that you, a thinking human with a functioning brain, should be able to just know without having to be taught specifically.

Of course it’s frustratingly uncommon sometimes, as the number of non-suicide train related fatalities would suggest.

Common sense generally refers to actions, thought processes etc. which are obvious, generally understood by the majority of a given demographic, and require little to no external explanation.

Common sense in simple terms is really simple to explain.

It’s the inherent knowledge in most functioning peoples’ brains that helps a person not die or get injured, basically.

It’s things like not walking in a highway, or jumping off a skyscraper just because.

There’s a difference between being suicidal and not having common sense.

It’s referred to as common sense because there’s usually a cognitive ability in our brain to distinguish between something that may cause us harm, and something that may not.

It’s common because most people have it, therefore making it, by definition, common.

Now we have to do courses to teach people this exact thing.

Because out of 100,000 people 1 person might think its a good idea to lick a electrical outlet. We need to teach everyone not to do such things.
