ADHD time blindness: how to make time visible

What time blindness is

Reviews of the research describe several differences in how people with ADHD handle time: estimating how long something will take, reproducing a length of time, and judging how much has gone by.¹ One group of researchers argues that time perception is so central in adults with ADHD that it should be treated as a core symptom.²

Russell Barkley, who helped make the term popular, has described ADHD as a kind of nearsightedness to the future. Things are either "now" or "not now". His practical advice is to externalize time: make it something you see, not something you feel.³

There is a second problem that affects everyone. People underestimate how long their own tasks take, even when they know past tasks ran over. This is the planning fallacy.⁴ With ADHD you get both at once.

What it looks like at a desk

• "Five more minutes" on one thing turns into an hour.
• You are late to things you care about.
• A deadline three weeks away feels like it does not exist, then it is tomorrow.
• You plan ten tasks for a day that could hold four.
• You look up and the afternoon is gone.

What helps

1. Make time a shape, not a number.

   Use a timer that shows time shrinking, such as a disc or bar. You can read it in a glance without doing math. A digital countdown asks you to remember to look and then to work out what it means.

2. Use clock times instead of durations.

   "This ends at 2:40" is easier to act on than "25 minutes". Write the finish time next to anything you start.

3. Find your multiplier.

   Time five ordinary tasks and compare each with your guess. If they took one and a half times as long, multiply every future estimate by 1.5. This uses your real history, which is the tested way around the planning fallacy.⁴

4. Add a "get ready" alarm.

   One alarm for the moment you must leave is too late. Add one 10 minutes earlier that means "start wrapping up".

5. Put transitions on the plan.

   Moving between tasks takes real time. If your plan has no gaps, it is already behind.

6. Work backward from the end.

   Start at the deadline and place each step before it. The first step often turns out to be today.

Advice that tends to backfire

• "Just pay more attention to the time." This asks you to use the exact sense that is unreliable.
• A timer you cannot see. A countdown in a closed tab or a locked phone does nothing until it rings.
• Estimating from how a task feels. Dreaded tasks feel long and interesting ones feel short. Neither feeling is a measurement.

How NoRush helps with time blindness

We make NoRush, so weigh this part with that in mind. The strategies above need nothing more than paper and a timer. This is how NoRush builds them in for time blindness:

• A shrinking disc timer in the app and in the bubble on every tab.
• Real clock times everywhere "ends 2:04 PM" and "done around 3:45 PM".
• It learns your multiplier and quietly plans with how long things really take you.
• A timeline for today that shows when each task would start, and warns you when the day is too full.
