Trust is a concept around personal choice and not facts. The feeling that you can trust something is what trust is.

For different people to get to that feeling means different things. A lot of people place trust in certain figures of authority, in politics or on social media. The reasons for which they do so differ wildly and very often have very little to do with ground truth (although I suspect most people would find that hard to admit).

When somebody says they can trust Wikipedia to be factually correct that mostly is a reflection of choices and what they believe helps them to navigate the world, in a way that is manageable and reasonable to them. Given that time is always a constraint to a varying degree, I think you could do a lot worse if being less wrong is your goal.
