Without looking it up, I believe the DSM says that diagnosis requires three out of five indicators. That would suggest that many people can get one or two indicators. Social media (specifically short form like twitter, instagram, and TikTok) has measurable negative impact on attention spans, while also propagating a narrative of colloquial symptoms.

“Whee look at me being neurodivergent!” - golly, I do that too! Maybe I’m ADHD.

For what it’s worth, I have both ADHD and mild autism. I’m not saying it doesn’t exist. I’m saying that the diagnosis is devalued by “oh i do that too, I’m also a little bit adhd”.
