A discussion on what we think they should study is probably ill-founded and a minefield.
The discussion around experts isn't about your theoretical "words, what do they mean?" no true scotsperson fallacy ("if they didn't know what they were doing, they're not really experts!!")
It's about whether we could and should trust the people in peak expert bodies like the UN/WHO (we clearly can't), bipartisan government expert advisers like SAGE (we clearly can't), government scientists and their peak expert overseers (we clearly can't).
It's a
practical consideration about how to proceed when expert bodies are at odds with common sense, and how to judge future odds correctly. This thread is full of classic examples - should we trust the WHO's belief/statements that this so unserious that it's a "very low threat to the globe" and that "stigma is more dangerous than the virus" and that "borders should not be closed"? We clearly shouldn't, yet many did. Read the first few pages of this thread (and the 2020 trading thread this was broken out from) - people were saying it was nuts to dismiss the WHO's take because "they're the experts, how can a guy on the Internet possibly know better?" These are actual questions that return $$$$ if you can reliably get it right, and clearly "trust the experts" is horribly flawed strategy.
Should politicians trust that experts like Fauci and Birx are going to minimally competent at their job, and do it better than a chimpanzee? They clearly couldn't; Fauci and Birx and the state expert apparaturs made horrible amateur mistakes that killed 80,000 people and counting.
Should we trust that experts can model correctly and understand the flaws of those models (for example, the UK's SAGE group relied on comically flawed modeling that said R0 can't get below 1, therefore it's best to have it go through the population as rapidly as possible, and just pile up the dead)? We clearly can't.
Can we trust, as individuals, they will advise on masks correctly? Nope. Whether we should "go out and be social with each other, live a normal life" as the pandemic is spreading, because it's "very low risk"? We clearly can't.
Whether we can trust experts is a practical consideration affecting everything from government policy to investments to personal safety, not some weird thing where everyone who screws up isn't an expert. The answer is overwhelmingly "we cannot trust experts ahead of common sense and simple rational analysis in most situations, and to a certainty in novel situations".

Thanks. I've been largely ignoring antibody test news, along with studies claiming results from them, because so much of the testing was so dubious. I'll have have to start following again.
Antibody tests are worthless for upper bounds on IFR, but are strong data for lower bounds on IFR. We have enough data now from antibody tests to know that IFR is around 1% and possibly higher; I consider the question largely settled.
