Searching for truth on the internet
The internet can be a confirmation bias machine. If one wants to find evidence that Wegmans is amazing, they will find it. If one wants to find evidence that Wegmans is terrible, they will find it. For that reason, I don't think anyone should celebrate when they find others online who agree with them. It feels like validation, but I believe it's meaningless.
Consensus is different. If almost all people who are knowledgeable about a certain subject agree on some fact, despite their different upbringings, cultures, and worldviews, then it probably is true. Can one find people online who believe that pandas speak Latin? Probably. The internet is a big place. Can one find broad consensus that pandas speak Latin? Absolutely not. That's one way of knowing it's probably bullshit.
Is broad consensus everything? No, but it's a strong indicator of truth. Add it to your truth detection scorecard. Have it replace “my tribe agrees with me.”
