Scott Adams writes in his book, "Win Bigly", that when you understand the psychology of persuasion, you are not impressed by the consensus of scientists because they are just as suceptible as ordinary people to mass delusions. According to the psychology of persuasion, mass delusion is actually the normal state of consciousness. This is particularly true for scientists studying climate change because their career and financial incentives are involved. In the following excerpt, 2-D is the normal world view and 3-D is Adam's world view that people are not rational but make decisions based on other factors and then use logic to defend their beliefs.
On top of our mass delusions, we also have junk science that is too often masquerading as the real thing. To the extent that people can't tell the difference, that too is a source of mass delusion.
In the 2-D view of the world, mass delusions are rare and newsworthy. But to trained persuaders in the third dimension, mass delusions are the norm. They are everywhere, and they influence every person. This difference in training and experience can explain why people disagree on some of the big issues of the day.
For example, consider the case of global warming. People from the 2-D world assume mass delusions are rare, and they apply that assumption to every topic. So when they notice that most scientists are on the same side, that observation is persuasive to them. A reasonable person wants to be on the same side with the smartest people who understand the topic. That makes sense, right?
But people who live in the 3-D world, where persuasion rules, can often have a different view of climate change because we see mass delusions (even among experts) as normal and routine. My starting bias for this topic is that the scientists could easily be wrong about the horrors of change, even in the context of repeated experiments and peer review. Whenever you see a situation with complicated prediction models, you also have lots of room for bias to masquerade as reason. Just tweak the assumptions and you can get any outcome you want.
Now add to that situation the fact that scientists who oppose the climate change consensus have a high degree of career and reputation risk. That's the perfect setup for a mass delusion. You only need these two conditions:
1. Complicated prediction models with lots of assumptions
2. Financial and psychological pressure to agree with the consensus
In the 2-D world, the scientific method and peer review squeeze out the bias over time. But in the 3-D world, the scientific method can't detect bias when nearly everyone including the peer reviewers shares the same mass delusion.
I'm not a scientist, and I have no way to validate the accuracy of the climate model predictions. But if the majority of experts on this topic turn out to be having a mass hallucination, I would consider that an ordinary situation. In my reality, this would be routine, if not expected, whenever there are complicated prediction models involved. That's because I see the world as bristling with mass delusions. I don't see mass delusions as rare.
When nonscientists take sides with climate scientists, they often think they are being supportive of science. The reality is that the nonscientists are not involved in science, or anything like it. They are taking the word of scientists. In the 2-D world, that makes perfect sense, because it seems as if thousands of experts can't be wrong. But in the 3-D world, I accept that the experts could be right, and perhaps they are, but it would be normal and natural in my experience if the vast majority of ciimate scientists were experiencing a shared hallucination.
To be clear, I am not saying the majority of scientists are wrong about climate science. I'm making the narrow point that it would be normal and natural for that group of people to be experiencing a mass hallucination that is consistent with their financial and psychological incentives. The scientific method and the peer-review process wouldn't necessarily catch a mass delusion during any specific window of time. With science, you never know if you are halfway to the truth or already there. Sometimes it looks the same.
Climate science is a polarizing topic (ironically). So let me just generalize the point to say that compared with the average citizen, trained persuaders are less impressed by experts.
To put it another way, if an ordinary idiot doubts a scientific truth, the most likely explanation for that situation is that the idiot is wrong. But if a trained persuader calls BS on a scientific truth, pay attention.
Do you remember when citizen Trump once tweeted that climate change was a hoax for the benefit of China? It sounded crazy to most of the world. Then we learned that the centerpiece of politics around climate change—the Paris climate accord—was hugely expensive for the United States and almost entirely useless for lowering temperatures. (Experts agree on both points now.) The accord was a good deal for China, in the sense that it would impede its biggest business rival, the United States, while costing China nothing for years. You could say Trump was wrong to call climate change a hoax. But in the context of Trump's normal hyperbole, it wasn't as wrong as the public's mass delusion believed it to be at the time.
I'll concede that citizen Trump did not understand the science of climate change. That's true of most of us. But he still detected a fraud from a distance. It wasn't luck.
