Hypercuriosity offers a useful lens for understanding many puzzling aspects of ADHD. It explains why attention shifts so readily in low-stakes, repetitive contexts, yet locks in place when a problem is urgent or rich with unknowns. It also helps many familiar features of ADHD fall into place. Rapid changes of focus reflect sensitivity to what feels promising in the moment. Distractibility reflects the presence of several competing leads, where attention is consistently drawn toward the most motivationally salient stimuli – whatever offers the greatest expected informational reward, whether that’s a new idea, an intriguing problem or an exciting possibility. And it might help explain more than is obvious at first glance. People often lose track of time when their attention locks on to something that feels immediately rewarding or mentally stimulating. The difficulty with boring conversations isn’t just about attention but about the painful absence of anything new to learn. Even racing thoughts at bedtime can reflect a mind that keeps generating new possibilities to explore, unable to stop asking ‘What if?’ or ‘What about?’ Taken together, these experiences point to hypercuriosity as a potential key driver of where attention goes and how long it stays there.
