There is an objective truth for the physical reality of things, but that truth immediately gets murkier as you step away from physics or into more abstract concepts. It is important to establish that objective truth is out there, but it is not sufficient, as many of these questions (from the article) can't be directly answered by reality: "Covid-19 escaped from a Chinese laboratory." is something that could be answered by reality one way or another, with a hypothetical perfect observer. A single fact could answer this question. "Climate change demands a radical transformation of modern lifestyles." This question is about the future, rather than the past, so it depends on our ability to assess the truth about predictions of objective reality, rather than merely to analyze objective reality directly. Reality can help us build better predictive models, but it can't decisively say if this statement is true or not. You could say that the future is part of the objective reality, but here we are forbidden from being able to perceive it at all. Finally, "Donald Trump colluded with Vladimir Putin to get elected." This one concerns only past events, it could definitely be resolved with knowledge about some specific fact from objective reality. However, in the absence of such a fact appearing we are forced to make decisions about the intents of people to make a judgement. I have trouble with the idea that this could be mapped directly to objective reality, ie something like collusion is an objective state of the brain that could be perfectly classified in theory. I think that our concept of "collusion" here is the problem-- it is simply not well defined enough to be used in a way that is not fraught with disagreement. Put another way, it is entirely possible that perfect observers of Trump and Putin would not agree with each other on this question, and that is a problem. To summarize, objective reality is important, it really exists and can of course be used to find the truth in many ways. But we are stuck with concepts that are not part of objective reality, when those concepts show up in questions, objective reality might not be of much help.
