1) Most are willing to admit they are wrong when an experiment result contradicts their theories.
2) Most are looking for the right answer, not the most profitable one.
I'd take that over our current Golden Rule model every time. Just look at leaded gasoline, waste disposal, or climate change to see examples of the golden rule hurting the average person. We have gotten rid of leaded gasoline, but it took one scientist nine years to convince the government that big business was lying. We're still fighting big business for good, long-term waste disposal and to minimize climate change
The only challenge I see is that, if we ever did switch to the Science Rule model, greedy idiots will claim to be scientists and put the true scientists in the minority, which would bring us back to the Golden Rule model anyway.
(I say Most in the bullets above because I'm pretty sure folks in it for the money these days wouldn't be scientists. But I also know there are a few bad scientists, so I sure as heck won't say 100%. I have no idea of how to test a scientist to see if they are good or not, other than to have well educated folks review a scientist's previous work.)
