Common sense is a rarity in people nowadays. This has created many problems, one of which is that people tend to listen to others’ opinions and accept them as their own thoughts, rather than trusting their own common sense and intuition. For example, they often rely on AI, doctors, celebrities, politicians, or other authority figures more than on themselves, who yes given plenty of incorrect information, allot of times intentionally. They might know something is a lie but ignore their skepticism because “Celebrity A” said it’s true. Sometimes, they even listen to their uninformed neighbors more than to themselves or to people on social media, who, ironically, also don’t listen to their own judgment. It’s a clown world.
It’s only one part. Other part is to test them yourself, don’t just take their word as fact, which is most important part. Examples, industries like tobacco funding in order to promote consumption of their product & downplaying harmful role of their product, countries releasing ranking of other countries who lacks “media freedom”. Most of this can be solved by peer review. and experts can be wrong sometimes, reminds me of episode of its always sunny in Philadelphia. And I think this paragraph is just common sense & whole post is was about soft sciences.
There is story about common sense in Panchatantra
In Mahabharata, When Grandfather Bhisma was instructing Yudhishthira about Dandaniti.
