Important Question: What Percentage of Scientists Are Useless Idiots?

So remember how salt is supposed to be harmful. We’ve heard that forever — the dangers of too much salt. In fact, Bloomberg has wanted to use the law to limit salt in New York restaurants, i.e., if you put too much salt on your food, he will send people armed with guns to stop you because salt is that dangerous as says Science!
Well… about that…
Yep, now they’re saying that salt is not harmful. In fact, increased might actually be beneficial.
Come on!
This raises an important question I think we need to explore as a society. Right now there is this way too high a reverence for Science! and we’re supposed to not question scientists and base our laws based on what they find, but my question is this: What percentage of scientists are useless idiots?
I mean, we all love science because it gave us lasers and computers and nuclear bombs, but my hypothesis is that it’s only a very small percentage of scientists who do any of this useful stuff and the much larger percentage are the ones saying, “Salt is bad for you! …No wait, salt is good for you! No wait…” They’re basically hippies in white coats with lots of pockets — completely useless. Well, except to carry things in their pockets.
My theory is that we revere scientists because we have a long memory for useful findings from scientists — because those we remember years and years later as we still use them — but a short memory for the much much more numerous dumb findings from science, because as soon as they’re disproven we forget them and move on.
The problem is, while it’s obvious a hundred years later which scientific findings are useful, we can’t seem to sort moron scientists from useful in the present day. And that makes the reverence of supposedly scientific findings (and it’s reverence of scientific findings and not science since science is a process and most people don’t engage in it) all the more harmful.
Anyway, if the government will give me millions to scientifically study this subject, I will accept and promise to be a useful scientist and not cause confusion and delay.
