In a recent post, I said I’m a very unenthusiastic person. I wouldn’t go so far as to say I’m never enthusiastic. But my husband says it took a while for him to internalize that e.g. when I say “yes” to a choice of restaurant, I really mean it, even if I don’t express enthusiasm. And that’s not a matter of communication style; if I appear unenthusiastic, I feel like I’ve communicated my internal state accurately.
Enthusiasm isn’t unique. I feel like most of my emotions are muted relative to the norm. Another really noticeable one is anger. My “anger”, such as it is, rarely rises above what I would call irritation. It’s not very visible. And I find it very difficult to maintain a grudge, even when I know intellectually that I should.
In short, I’ve always felt like I must be experiencing emotions differently from most people–not necessarily in a neurodivergent way, but just somewhat outside the norm. I don’t know of any preexisting term for this, so I’m dubbing it “low emotionality”. Wikipedia describes “emotionality” as emotional reactivity to a stimulus, so I think the term fits. I never see anyone talk about low emotionality, so I’m being the change I want to see.
