it’s important to have verifiable studies to cite in arguments for policy, law, etc.
It’s also important to have for its own merit. Sometimes, people have strong intuitions about “obvious” things, and they’re completely wrong. Without science studying things, it’s “obvious” that the sun goes around the Earth, for example.
I don’t need a formal study to tell me that drinking 12 cans of soda a day is bad for my health.
Without those studies, you cannot know whether it’s bad for your health. You can assume it’s bad for your health. You can believe it’s bad for your health. But you cannot know. These aren’t bad assumptions or harmful beliefs, by the way. But the thing is, you simply cannot know without testing.

I have wondered the same about scammers. Like, if their mother knew they were going to do that with their life, she’d probably regret all of that wasted effort raising them.
