The Myth of Multitasking

In the 1960s, computer scientists coined the word "multitasking" to describe how a single processor could juggle several jobs by switching between them faster than the human eye could detect. The word was a flattering metaphor for what computers did. By the 1980s, however, it had quietly escaped the laboratory and reattached itself to human beings. We were now expected to multitask too — to do everything, at once, and to look good while we did it.

Phrasing · read this paragraph aloud and break it into natural thought groups. Mark a tiny pause at each comma and notice how the meaning lands more cleanly when you do.

The trouble is that the analogy was wrong. The American neuroscientist David Strayer, who has spent decades studying attention in his Utah laboratory, estimates that only about 2% of the population are genuine "supertaskers" — people whose brains can run two demanding tasks in parallel without measurable cost. The rest of us are doing something subtly but importantly different: we are engaged in rapid task-switching, jumping back and forth between jobs and paying the cost of context-switching with every single jump.

Sentence stress · read aloud and underline the three or four content words in each sentence that take the heaviest stress. Function words (the, of, with, are) should slip past almost unnoticed.

A landmark 2009 study at Stanford University tested students who described themselves as gifted multitaskers. The researchers expected to discover that these students had developed superior cognitive control. Instead they found the opposite. Heavy multitaskers performed worse on every measure tested — they were more easily distracted, slower at filtering out irrelevant information, weaker at switching tasks deliberately. Their attention had been spread far too thin; the cognitive load they were carrying was heavier than they realised; and they were running, in effect, on autopilot through the very activity they thought they had mastered.

Linking · notice how, in fluent speech, words bleed into each other — "studies_at Stanford", "more_easily distracted", "in_effect". Practise the linking; don't separate every word.

What is striking, however, is that the multitaskers themselves had no idea. Their habits felt deceptively productive: the constant switching produced a steady sensation of busyness — and busyness is something our culture has, perhaps mistakenly, learned to mistake for effectiveness. Worst of all, almost none of them had compartmentalised their day in any meaningful way; work, messages, half-formed plans and personal life all bled into the same hour. The cost was real, but invisible from the inside.

Intonation · this paragraph turns on a contrast — felt productive against performed badly. Listen for the falling intonation on each side of the pivot, with a small rise on the contrast word itself.

The implication is uncomfortable. If we want to do good work, we may have to give up a story we rather like about ourselves. Single-tasking — the unfashionable opposite — sounds slow and old-fashioned. Yet on every quiet measure that genuinely matters, it appears to win. The deeper problem may not even lie with us. We now live inside an attention economy whose entire business model is to fragment that single task before we ever get the chance to finish it.
