Here is the thing. Science is hard. Thinking is hard. Most people would rather live a comfortable lie than facing the cold, hard truth.
Sadly I agree that the first two apply to an awfully large portion of the population, in the U.S. and elsewhere. Your third point is often true but that isn't what is always at work.
Often what is going on is that people become exhausted with argument and just want an answer - any answer. I watched a small group of people who thought they had a problem argue for years about whether the problem existed. The people who believed the problem existed were scared. The other people didn't want didn't want to spend large amounts of money (several 10's of thousands of dollars each) on something they didn't believe was a serious problem.
Both sides were tired of arguing. Along came a guy with an engineer in his pocket (or vice versa) and the engineer told them the sky was falling. He offered to do an engineering assessment for less than half what any reputable company would have charged and they went for it.
The flunky sent to do the study wasn't even an engineer. Then there was another meeting. I have worked with a lot of engineers and they would never have made the kind of statements the head guy was making at that meeting. He also said a lot of things that I knew were put in a very biased way but there was no good way to put this across to people who didn't have the intellectual skills to understand.
I suggested that before they committed to spending what would be a huge amount of money for each that they get a second opinion from another engineering company - a proper study would cost < 1% of the proposed project budget. People agreed but the elected committee put in charge cut the report budget to about 25% of what was needed and placed other restrictions on the 2nd company - to the point where the 2nd report was prefaced with disclaimers about this and stating that they were prevented from making necessary measurements.
So that second report said not much of anything and the project was pushed ahead. The people on the committee didn't want to have a dissenting opinion. They didn't want to have to argue about the facts. They didn't want to know the truth. And the whole group of people didn't want to have yet another fight about the whole process so they just went with the 1st engineer's recommendations. They didn't even take the simple precaution of eliminating the bias introduced by profit incentive by starting the whole process by making it clear that the companies who did the reports would not be the engineering company that would eventually be hired to do any work.
It was all very predictable - the group that thought there was a problem got someone to say they were right They didn't take precautions to ensure the people giving the opinion were as unbiased as possible and then prevented any chance of getting a contradictory opinion.
The other faction would probably have done similar things if they had had the chance. The only thing everybody had in common was that they wanted some resolution, any resolution, whether right or wrong. Half way through the project, when it was too late to turn back, it turned out the problem was nothing like what had been predicted - one guess as to whether anyone would admit that.
People want answers. Frequently they are not equipped to personally judge the answers they are given. Then they are given dissenting opinions which they are also not equipped to judge. Arguments rage back and forth. Eventually emotional burnout ensues and they just want any answer so it will be over with. Once they reach that point there is nothing, no fact, no logic, that will budge them.
