The simple reality is scientists don't say things people like.
If you ask a scientist what you should do about your medical condition, they say unhappy, unreasoning things like "the best data we have at the moment says you should do X and it has a 63% chance of showing some improvement but you need to watch for side effects A, B, C, and D"
If you ask a homeopath or other snake oil salesman what you should do about your medical condition, they say happy, reassuring things like "You should do Y. I'm sure it will help and it has no side effects".
Scientists suck at selling things including themselves, and politics is all about selling yourself.
