This linking of alexithymia to autism has caused harm by making it harder to get the diagnosis for people who can recognise emotion within themselves and others.

In particular, some clinicians seem to think that everyone has the same baseline interoceptive experience and that any problem with identifying emotions is therefore purely a problem of attention or vocabulary.
