Why, with ADHD, time can feel imprecise, why reminders don’t always help, and what external supports work in practice.
A person with ADHD is not late because they do not respect other people’s time. And they do not postpone a report because they do not care about the outcome. In both cases, the same malfunction is at work: time is perceived inaccurately. It is not “poorly planned” — it is perceived, at the same level as sound volume or distance to an object. An hour can feel like twenty minutes, and “in two weeks” can feel like “never.” This malfunction is described by the term - time blindness, and it explains a significant part of what appears to be irresponsibility from the outside.
Time blindness is not included in the formal diagnostic criteria for ADHD, but it has been described in the literature for a long time and consistently—largely thanks to the work of Russell Barkley, who viewed the deficit in time regulation as one of the key core manifestations, rather than a side inconvenience. It manifests in several recognizable forms.
The first is a systematic underestimation of how long things will take. “This will take ten minutes” turns into forty, and it happens every time, despite all previous experience. Experience accumulates poorly here precisely because the estimation is not based on memories of past attempts, but on a feeling in the moment.
