Maybe, but the brain cannot handle two complex tasks at once, so what looks like clever multi-tasking is more often switching quickly between two or more tasks. This is an inefficient way of working because the brain has to both decide when to switch and remember each task. In many laboratory tests, men and women do equally well. In a more realistic study, men and women under time pressure had to juggle simple mathematics problems, answer the phone and decide how to find something lost in a field. During the study, the women were found to be calmer and better organised than the men. But even if this difference is real, we still don’t know whether it is biological or culturally imposed.
