> To me it's obvious there are areas that are under-researched by academia. ... Climate change skepticism.

Why would anyone research "climate change skepticism" and not just "climate"? The very idea of a discipline with "skepticism" in it's name suggests that there is an existing answer that someone is looking for, whereas the whole point of science is to keep an open mind. Nobody researches "physics skepticism", they research physics.

If you presuppose an outcome, you're not really doing science.

That's sort of the trouble - mainstream climate change research seems to be lacking skepticism when it comes to claims that we're all doomed. For example, there was a paper in Nature which claimed the oceans were soaking up 60% more heat than previously thought, which implied CO2 caused much more warming than previously estimated. This made it onto most of the world's news and HN: https://news.ycombinator.com/item?id=18352506 It should've caused skepticism, since it used a weird indirect method to estimate something that was measured directly and contradicted both the direct measurements and the models. It didn't. It took some of those academic outsiders to spot that they'd screwed up the error bounds and, in fact, this weird method wasn't able to measure ocean heating accurately enough to contradict the existing measurements. The researchers did at least admit some of their errors, which is not something that can be relied on in any field.

The HN comments are quite amazing in retrospect too. Lots of comments proclaiming our doom, with tthe topmost one starting "yet more bad news on the climate change front", one not-particularly-insightful downvoted comment at the bottom suggesting that a 60% change in an important measurement shouldn't inspire confidence in climate science's accuracy.

That isn't enough. Mainstream physics research lacks skepticism about the laws of thermodynamics. Mainstream biology lacks skepticism about cell division.

When evidence for a proposition is strong, skepticism is weak.

If you want to argue for climate change skepticism, you have to provide evidence for to raise that skepticism. Yet every time someone does so, it gets shot down.

Yes, I agree. That was poorly phrased by me.

What I mean is that academia finds it structurally impossible to do research that ends with the conclusion that maybe there's enough research done into something for now, that perhaps there's no problem that requires this sort of academic attention, or perhaps we lack the tools to make useful predictions in a field at the moment. There are no feedback loops.

Imagine you go into a very small, very closed field like climatology or economics, do some research, and your conclusion is this: "climate is too complex for us to model with any certainty, our data sets are corrupted and low quality, we really have no idea what's going on and can't fix this any time soon". Or even "the climate is changing but not in any actually problematic way, there's nothing to do here".

This may well be a legitimate or correct conclusion (for any field of science), but it's also a career-terminating one. Research into the question of how effective research can be just doesn't get done by academia because there's no ground truth end goal - research isn't a means to an end, as in the private sector. In academia research is itself the end.

This is what I'm trying to get at. To leave climatology for a moment, look at how long it took for replication studies in psychology to start at any scale, and how much science - for decades - has been found to be completely bogus. It's a staggering amount. Every time I read something about the replication crisis I'm stunned by the enormous scale, and how much more there seems to be to uncover. Academia has simply not been funding "psychology skepticism" and to a large extent still isn't. The production of large amounts of nonsensical research is guaranteed by the incentive structure of academia, in which research is entirely self-justifying and in which it doesn't pay to shoot down colleagues in your own field.

You’re presenting as argument a non-issue and distracting from the real issue. They are researching climate. What GP seems to be referencing is that they’re coming to a different conclusion and are being assaulted for it.
