Focus and attention

Why concentration feels harder than it used to, what’s really going on in your brain when you get distracted, and what helps.

Attention is the gatekeeper for everything else your brain does. Information you don’t pay attention to never gets stored, which is why so many “memory problems” are really focus problems. The guides below look at what the research says about attention, and at the myths, like the goldfish attention span, that get repeated without evidence.

Start with attention span for the overview, or multitasking if you’re juggling too many tabs. The guides to dopamine and caffeine explain two of the biggest chemical influences on how alert and motivated you feel.

Frequently asked questions

What is the average attention span?

There isn’t a single number. The claim that humans have an 8-second attention span, shorter than a goldfish, has no solid source. How long you can focus depends on the task, your interest and how tired you are. See average attention span.

Is multitasking bad for your brain?

Switching between tasks costs time and accuracy, and heavy media multitaskers tend to do worse on some attention tests. See is multitasking bad for your brain?

How can I improve my focus?

Work on one thing at a time, remove easy distractions like phone notifications, take real breaks, and protect your sleep. Short meditation practice helps some people.

Does caffeine help you concentrate?

It makes you more alert, especially when you’re tired, but that’s not the same as making you smarter. See caffeine and memory.
