Den [[Sverige|svenske]] klimaaktivist [[Greta Thunberg]] lider af selektiv mutisme.<ref>Greta Thunberg (12. december 2018) https://www.youtube.com/watch?v=EAmmUIEsN9A Ved TEDxStockholm, "I was diagnosed with Asperger's syndrom, OCD, and selective mutism. That basically means I only speak when I think it's necessary. Now is one of those moments... I think that in many ways, we autistic are the normal ones, and the rest of the people are pretty strange, especially when it comes to the sustainability crisis, where everyone keeps saying that climate change is an existential threat and the most important issue of all and yet they just carry on like before."
