know nothing about.
People send me all sorts of blog posts and social media posts about this or that because of my field of study and I gently ask them how they know this person.
Usual response: “She’s a mom I follow on Instagram” or “He’s a mechanic I watch on YouTube” or “she’s really smart about these things (meaning, I really agree with her)”.
People believe fame is equivalent to expertise. It’s not. Nor is opinion.
