Best way to fact-check news?

I just read that oil markets are being deliberately manipulated to drive prices higher and make the impact on the population worse. Before I share or act on it, I want to verify if it’s true.

What are your go-to methods or tools for fact-checking economic or political news? Also, which communities on Lemmy (or the wider fediverse) are best for this kind of thing?

Thanks for any tips!
