Yes, it's hard for some to believe, but there are people in my family who are otherwise very intelligent but will not change their opinions on some things. Like climate change.
It would be great if what you said is true, and people were just arguing about what to do about it.
It's not, though. "It's a hoax" is both the start, and the end point for a large portion of the population, the media, and the politicians that represent it.
In absolute terms, the portion of the worlds population that deny that the climate is changing is a single digit percentage, and that include the US (https://en.wikipedia.org/wiki/Public_opinion_on_climate_chan...). The portion is a bit larger if you include people who think that the climate is changing but that is mostly caused by natural causes, but it is still a small minority compared to the wast majority that see climate change as either caused exclusively by human activity or as a mix between human activity and natural causes.
The "It's all a hoax" is a popular talking point but their followers are fewer in real life. It much more commonly to find that people with opposing view who actually agreeing that climate change is real, but that they disagree on policy. As an example, creating environmental policy based on per capita create a complete different policy compared to absolute emissions. The later is no more climate change denial than the first, and yet the later generally get labeled as denial.
I don't need to trust what the media tells me about them, I can just listen to what those people and the politicians elect actually say, and what they say is flippin' 'Climate change is a chinese hoax' lunacy.
There's no need to sanewash them, or make excuses for them. It's not a matter of 'disagreement of what to do', it's that they are either really fucking stupid, or are disingenuously courting people who are really fucking stupid.
You probably don’t actually listen to what they say. You probably instead listen to what your preferred media channels report on, and selectively quote from, what they say. You think these two things are the same, since you think that your news sources are perfectly accurate. But those who actually listen to those people, and prefer different media channels, probably have other opinions.
I'll admit, I'm a simple man and I don't know the science behind all of this. But as a citizen, it does feel confusing how one day you're being told that we're all going to die unless we change something, and then suddenly even though nothing changed, it seems to be fine after all.
If you think that everything "seems to be fine after all", you're in for a very rude awakening.
For context, here's one source saying public concern for climate change has fallen in Germany from 42% to 34% from 2022 to 2025, in line with other European countries. [0] This was a study done by a German sustainability non-profit.
Here's another source stating that globally, news coverage about climate change has diminished by 38% from 2021 to 2025. [1]
Here's a third source stating that the share of German citizens who claim to be "very concerned" about climate change has dropped from 50% to 33% from 2019 to 2025. [2]

Neither side’s behavior can be considered “more intelligent” when you consider the vast majority of people on both sides are “opinion-takers” simply conforming to received social norms about what to believe about the world. The “opinion-makers” on both sides are undoubtedly intelligent, although you might prefer to call one side “cunning” instead.
We are lied to constantly by people who influence our lives. You can't even go to the grocery store without being lied to - being told breakfast cereals are healthy, that low fat options will make you less fat, shrinkflation, misleading unit pricing. It's no wonder people are so distrusting
Even if you're a democrat you still have to admit that democrats lie, a ton, and it's super obvious. Maybe if our leadership in general, on both sides, was capable of being decent humans then we'd be able to build trust and stop doing dumb shit as a civilization
If you tell the nuanced truth and lose, and your opponent tells simplified untruths and wins, where does that leave you?
As I understand it (obviously a gross simplification), Jimmy Carter attempted to treat Americans like adults, but Americans did not want to inconvenience themselves by wearing sweaters
Current research papers are far more advanced, but they're about the details of climate change. The basic facts of it were established two centuries ago.
We know that we are putting CO2 into the atmosphere. We know that CO2 absorbs heat. That's not a matter of believing an expert. At this point, anybody still denying it is deliberately choosing what somebody else tells them.
The economic effects of that are harder to model, but denialism is still stuck on whether the effect is real. There is no way to include them in any coherent discussion of what to do about it.
