Scientists have recently discovered an intriguing paradox. The very feature that makes multi-tasking bad, can make multi-tasking extraordinarily good — in one precise context, stress.
Multi-tasking interferes with decision-making because you’re not giving your brain the chance to focus for long enough on the problem. Stress harms decision-making by making your brain process information in a less rational way.
As you might expect, you make bad decisions if you’re either multi-tasking or stressed.
But not, it seems, if you’re both at the same time.
