Why do some conspiracy claims stay impossible to sort out?

Start by separating three things: what is known, what is inferred, and what is still unknown. A claim can sound plausible without being established. Ask what specific evidence would support it, what evidence would count against it, and whether the claim changes whenever it is challenged. If no possible result could make the claim less likely, it may not be testable in a useful way.

That does not mean secret coordination never happens. It means each allegation needs its own evidence, and uncertainty is not proof either for or against it.

Sometimes the issue is that the evidence people want simply is not public. But “it’s being hidden” can’t do all the work of proving a claim. I’d keep the conclusion modest: say what the available material shows, and leave the rest as an open question.

There’s a difference between proving a claim and doing something about it. Even when evidence is credible, investigating or responding can depend on having clear records, a specific allegation, and some body with authority to examine it. Vague suspicions are hard to act on because there’s no clear claim to check.

A practical next step is to write down the allegation in one sentence, trace each part to a source, and mark gaps plainly. If the trail stops at anonymous assertions or repeated speculation, that is a reason to withhold judgment, not a reason to fill in the missing pieces.
