From Naomi Fisher on Twitter:
In 2020, a student heard about object permanence in his undergrad psychology course. Object permanence is an early developmental stage when children come to understand that an object is still there, even when they can’t see it. It is acquired around the age of 18 months. Without it, we’d be profoundly disabled. Dogs have object permanence - if they didn’t, they would not chase after balls.
That student made a TikTok video, claiming that object permanence was actually a symptom of his ADHD. He said when he couldn’t see things anymore, it was like they did not exist for him. Others picked it up and more videos appeared. It spread. Blog posts were written which described fairly typical forgetfulness, and called it object permanence. Walk into a room and forget what you came for? Perhaps you lack object permanence, and therefore have ADHD. The more it was talked about, the wider it spread. Infographics appeared. Losing your keys could, apparently, be a sign of poor object permanence.
By 2025, parents were telling me that their teens had poor object permanence, and that’s why they couldn’t keep up with friends.
By 2026, author and influencer Alex Partridge wrote in his bestselling book that object permanence was a symptom of ADHD.
Object permanence went from one undergraduate’s TikTok video to mainstream acceptance within a few years. Most people now have no idea where it came from, or what the original concept of object permanence was. It’s become part of ADHD.
And that’s how new ideas are emerging and gaining credibility in neurodivergence. No science, no scrutiny - all it takes is a TikTok post and a catchy name.
Owen Chevalier tracked the evolution of object permanence in his paper, referenced below.
Are there other terms like this that you’ve noticed emerging?
