I’m an entomologist. Morgellons is a new flavor of delusional parasitosis. I get people with Morgellons and DP sending me matchboxes filled with hair, lint, skin flakes and other crap (this is actually a clinical sign of DP - its called “matchbox sign”), and emailing me pictures of same. I’ve never once in 10 years been sent something identifiable as being of insect (or even animal) origin.
All I can say to them is that in my professional opinion, the specimens they sent me are not consistent with insect or arthropod infestation, and suggest they see their doctor. I used to suggest they see a mental health professional, but that usually goes down like a lead balloon, and I don’t do it anymore.
Now, I’m not mocking these people. I feel really awful for them, they are usually near their breaking point. DP is a serious mental illness. But its hard to treat, because they are very resistant to treatment. No one likes to be told they are crazy - they just keep flitting from one practitioner to another until they find someone unscrupulous that will take advantage of them peddling quack remedies. Then they get REALLY resistant to treatment - its kind of like being in a cult.
The internet has sped this process up, unfortunately.
Is anyone else here familiar with Skeptoid? It’s a very good podcast and website dedicated to critical thinking. Brian Dunning, the man behind it, doesn’t just dismiss or debunk, but he seriously examines a claim (or pop phenomenon, or bit of pseudoscience, etc.), researches it, and only then points out where, how, and why it goes wrong.
