You've probably seen the claim: humans now have a shorter attention span than a goldfish. Eight seconds, apparently. It gets cited in parenting articles, corporate presentations, and school newsletters. There's one problem with it.
It was made up.
Where the number came from
The eight-second figure traces back to a 2015 Microsoft Canada report. When the BBC investigated the claim in 2017, they found the report cited a company called Statistic Brain as the source. Statistic Brain couldn't provide a credible origin. The National Center for Biotechnology Information and the US National Library of Medicine, both named in the citation chain, had no record of any such research (Various analyses, 2026).
The goldfish comparison has no scientific basis either. There is no standardised measure of goldfish attention. The number was fabricated, and it spread because it felt true, not because anyone checked.
What the research does show
Gloria Mark, a professor of informatics at UC Irvine, has tracked how people use screens since 2004. In her early studies, people spent an average of two and a half minutes on any given screen before switching to something else. By 2012, that had dropped to 75 seconds. Her most recent measurements place it at around 47 seconds (Mark, 2023).
That sounds alarming until you notice what's being measured. It's task-switching behaviour in digital environments, not biological attention capacity. The same person who switches tabs every 47 seconds can sit through a two-hour film or read for an hour if the content holds their interest.
Attention span isn't a fixed trait. It's task-dependent.
What this means for toddlers
Young children are the same, only more so. A 2-year-old who "can't sit still" during a structured activity might spend ten minutes watching ants on the pavement. A 3-year-old who won't engage with a worksheet might focus intently on pouring water between cups.
The variable isn't the child's capacity. It's the match between the task and the child's interest. When the activity connects to something a toddler cares about, and when it moves at a pace they can follow, attention tends to take care of itself.
This is part of why a 2025 study in Child Development found that just a few minutes of daily app use was enough for meaningful learning gains (Niklas, 2025). The children weren't using the apps for long periods. They were using them with focus, because the content engaged them.
The useful question
If your toddler seems easily distracted, the question that tends to be more productive than "what's wrong with their attention?" is "what's wrong with the task?" A slow game at their pace, with clear cause and effect, will often hold their attention in a way that surprises you.
