In a set of experiments published in Science in 2014, psychologist Timothy Wilson and colleagues gave 55 undergraduates a stark choice: sit alone in a bare room for 15 minutes with nothing to do but think, or press a button and give themselves a mild electric shock — the same shock they had already sampled and said, beforehand, they’d pay money to avoid. Eighteen of the 42 who’d made that payment pressed the button anyway, at least once, during the 15 minutes they were supposed to just be thinking.
The setup was deliberately spare. Participants were left in an unadorned room, phones and reading material removed, with instructions to just sit and think about anything they liked for a set period — six or fifteen minutes, depending on the specific experiment in the series. Before that period began, they’d been given a taste of a mild electric shock from a device attached to their ankle and asked to rate it; enough of them found it unpleasant enough to say they’d pay real money to avoid a second one. Then they were left alone with a button that would deliver that same shock, and told the choice to press it was entirely theirs.
What the numbers actually showed
Wilson and his co-authors reported that a meaningful share of participants shocked themselves rather than sit with their own thoughts for the full period — roughly two-thirds of the men and about a quarter of the women, with the pooled rate landing close to 43 percent overall. The researchers’ interpretation was direct: for a lot of people, entertaining yourself with nothing but your own mind for a quarter of an hour is hard enough that a jolt of mild pain is, for some, the more attractive option. That’s a strange enough result to spell out clearly what it doesn’t show: nobody in the study was forced to press the button, nothing bad happened if they simply sat still, and the shock was never framed as a way to end the session early. The only thing on offer was a brief jolt of discomfort in exchange for a brief break from their own unstructured thinking.
Why some psychologists think “boredom” is the wrong word
Not everyone accepted that reading. In a commentary published later that year in Frontiers in Psychology, researcher Kieran Fox and colleagues went back to what shockers actually said when asked why they’d done it. Of the 18 people in that particular sample who administered a shock to themselves, 14 described some form of curiosity about the shock itself — what it would feel like, whether it was as bad the second time — as their reason. The rest gave a mix of other reasons. Fox’s team argued that curiosity and escape from an unpleasant state are different psychological processes, and that Wilson’s framing had collapsed the two.
Why Wilson’s team didn’t buy the curiosity explanation
Wilson and colleagues answered Fox’s critique directly, in a reply in the same journal, and didn’t concede much ground. Their central objection: asking someone why they did something after the fact produces a plausible-sounding story, not necessarily an accurate one. They also pointed out that every participant who shocked themselves had already felt the shock and rated it unpleasant enough to pay to avoid — a strange thing to be merely curious about a second time. And the shock data wasn’t their only evidence: across the broader set of studies, somewhere between a third and just over half of participants broke the instructions altogether, getting up, checking a phone, or doing anything other than sitting and thinking, which is difficult to explain as simple curiosity about electricity. More than a decade later, the disagreement between the two readings hasn’t been resolved in either group’s favor — a reminder that a single, clean number rarely survives contact with the people who actually generated it.
What this means for anyone whose job is holding someone’s attention
Bloggers, newsletter writers, and video creators live and die by a version of the same question the shock study raises: how much unstructured, unentertained time will a person actually tolerate before they’ll do almost anything to escape it. A slow-loading page, a paragraph with no hook, a video with a dead ten seconds in the middle — each one is asking a reader or viewer to sit with functionally nothing, and the shock study’s headline number suggests a meaningful share of people would rather do something mildly unpleasant than tolerate that gap. The disagreement over why doesn’t change the practical lesson: dead air is a cost, whatever the psychological label for the discomfort turns out to be. A newsletter that opens with three throat-clearing sentences before it gets to the point is asking readers to sit through their own smaller version of that empty room, and plenty of them will click away rather than wait it out.
The number worth keeping
Eighteen of the forty-two people in that room chose a shock they’d already said they’d pay to avoid over fifteen minutes of unstructured thinking. Whether that’s boredom, curiosity, or something psychologists haven’t yet named precisely enough to agree on, the number itself hasn’t moved in over a decade of arguing about it.
