The modern workplace places a premium on the ability to juggle multiple tasks simultaneously, and (0) YET research consistently demonstrates that true multitasking is, for all practical purposes, a myth. What the brain actually does when we attempt to perform two cognitively demanding tasks at once is switch rapidly between 1, a process that carries a significant cost in terms of both speed and accuracy. So ingrained 2 the belief in multitasking become that many employers still list it as a desirable skill 3 the face of overwhelming evidence to the contrary. Numerous studies have shown that those who consider 4 to be expert multitaskers are, in fact, among the worst performers when tested under controlled conditions. Had the findings of early cognitive research been more widely publicised, the misconception might not 5 so widespread today. Not only does switching between tasks reduce the quality of one’s work, 6 it also increases the likelihood of errors — a fact of which many professionals remain blissfully unaware. Difficult 7 it may be for employers to accept, the evidence is now beyond dispute: the human brain was simply not designed to do two things at 8, and no amount of practice will change that fundamental limitation.
