What does Time blindness mean?
Difficulty sensing time passing: five minutes and two hours weigh the same until lateness arrives.
Definition
Time blindness is a metaphor borrowed from sight, not a DSM diagnosis. Russell Barkley used the image for ADHD: the inner clock does not govern behaviour. He talks of now and not-now. The picture also shows up in autism, anxiety, injury.
Five minutes and two hours weigh the same until lateness arrives. The external timer is the clock from outside. Poor calendar management, when a person estimates well and still fails to plan, is a different problem.
Origin
English joins time to blindness. Barkley, ADHD and the Nature of Self-Control (1997). The paper “Attention-Deficit/Hyperactivity Disorder, Self-Regulation, and Time” ran in the Journal of Developmental and Behavioral Pediatrics in August 1997 (18(4):271–279), with the line “blindness to past, future, and time.”
History
From the 1997 paper the metaphor reached the I'll be there in 5 meme. ADHD communities and TikTok picked up the image in the 2010s–20s. DSM-5 does not list the name; the inner clock is still the picture Barkley described.
How it emerged
Late again needed a name that was not only disrespect. What was missing was the short image for now and not-now; Barkley stuck blindness onto time and the feed repeated the nickname.
Usage examples
Said five minutes and showed up two hours later.
The stove timer replaces the clock that does not sound.
