TL;DR:<\/strong> When you move from one task to another, a slice of your attention stays behind on the first one. Psychologist Sophie Leroy named this attention residue<\/strong> in 2009, and her research found it is worst when the task you just left was unfinished or done under time pressure<\/strong> – which is the exact state a half-finished prompt or a “still generating” window leaves you in. The AI era makes this acute for a simple structural reason: AI returns work in seconds, so a single hour now contains far more handoffs between instructing a machine<\/em> and collaborating with people<\/em> than a pre-AI hour ever did, and every handoff leaves residue. The verified costs are large: it takes about 23 minutes<\/strong> to fully return to an interrupted task (Gloria Mark, 2008), switching can burn up to 40% of productive time<\/strong> (APA, 2001), and knowledge workers already toggle between apps roughly 1,200 times a day<\/strong> (HBR, 2022) – all before you add AI, which 75% of knowledge workers now use at work<\/strong> (Microsoft and LinkedIn, 2024). This article turns those findings into an original Human-AI Switch Ledger<\/strong> and a scoreable self-audit<\/strong>. The move: budget your switches the way a CEO allocates scarce capital, and stay enough of a student to learn where your own residue leaks fastest.<\/p>\n<\/blockquote>\n

You sit down to write something hard. You hand a chunk of it to an AI – “draft the intro” – and while it generates, you flick to Slack, answer a colleague, glance at email, then come back to judge the AI’s output. The whole loop took ninety seconds and felt efficient. It wasn’t. You left at least three tasks half-open, switched cognitive modes four times, and came back to the writing carrying the residue of all of them. The draft on screen is fine; your ability to evaluate it is not. This is the quiet tax of working alongside machines, and almost nobody budgets for it.<\/p>\n

The science behind that tax has a name and a clear origin. In 2009, organizational psychologist Sophie Leroy published a paper with a title that sounds like a sigh: “Why is it so hard to do my work?”<\/em> Her answer was attention residue<\/strong> – the finding that when you switch from Task A to Task B, part of your attention stays cognitively stuck on Task A, and that lingering residue measurably degrades your performance on Task B. The effect, crucially, is strongest when Task A was unfinished<\/strong> or done under time pressure<\/strong>. The AI era did not invent attention residue. It industrialized the conditions that produce it.<\/p>\n
