The Myth of Multitasking
Read about why parallel work falters under scrutiny and practise cleft sentences with it-clefts, what-clefts, and the-reason clefts.

It is the brain itself that struggles to attend to two things at once, despite the cultural enthusiasm for multitasking. What we call multitasking is actually rapid switching: the mind detaches from one task, reorients itself, and re-engages with another, often within the space of seconds. The reason this matters is that each switch carries a cost, small individually, but accumulating into a serious tax on attention by the end of a working day.
It was a series of experiments at Stanford that first popularised this finding. What surprised the researchers most was that the heaviest multitaskers performed worst on tasks requiring focus. The very people who most insisted on their fluency in juggling streams of information turned out to be the least capable of filtering relevant signals from noise. It is precisely this confidence-skill inversion that makes the myth durable: those who practise multitasking most are the least likely to perceive its damage.
What modern offices reward, however, is precisely the appearance of multitasking, the open laptop in the meeting, the inbox refreshed during a phone call, the half-attentive glance at a colleague while typing. It is the visibility of effort, rather than its quality, that is celebrated. The deep work, which some researchers have begun calling ‘monoidealism’, is rarely visible and seldom rewarded; it is the buzz of fragmented engagement that registers as productivity.
What the research suggests is not that we abandon parallel processing entirely. It is unrealistic to expect that anyone will work in monastic seclusion. What is needed instead is a saner sense of which tasks tolerate switching and which do not. Email, low-stakes admin, and routine errands can be interleaved without much loss; what cannot survive interruption is creative thinking, complex analysis, and any task that requires holding several variables simultaneously in mind.
The reason this distinction matters is practical. It is in protected blocks of unbroken attention that difficult work gets done, the proposal that finally makes sense, the bug that finally yields, the chapter that finally writes itself. The cost of pretending otherwise is paid not in dramatic failure but in a steady, unnoticed mediocrity: the long meetings, the unfinished drafts, the days that disappear without a trace.
