armchair diagnosing is dangerous

In the article linked above, they discuss one social media influencer who has created an 8 part documentary series examing the perceived mental health issues of another social media influencer.

One of the concerns that gets examined is the idea that they lump bad behaviour in with mental health issues.  This can have the impact of increasing stigma for those who deal with mental health issues.

Another concern noted is that the one influencer is talking about the other influencer and pathologizing his behaviour.  There have been many instances in the Trump era, for example, where the press will be discussing his behaviour, they have a psychiatrist/psychologist on talking about that behaviour, with a disclaimer running on the screen: "Dr. X has not treated this person" and again, they are categorizing his behaviours as mental health issues.

A third concern, is that some viewers (in the millions) may be watching these videos and take the information as accurate or as true news.  This can again be stigmatizing for the person who has mental health issues.  Certain terms get tossed around in popular media or popular culture which are untrue or are quite difficult to diagnose or rare and suddenly the media is diagnosing everyone in the news.

I fear that  the young person with struggles, sees how some celebrities get villified and labelled with a diagnosis and doesn't seek support.  

If news casters and social media influencers would stick to describing behaviour and not labelling and armchair diagnosing then I wonder what the impact would be.

What do you think?  Have you had any reactions to armchair diagnosing in the news lately?
