Checking it may provide a welcome distraction from more difficult and challenging tasks. It helps us feel, at least briefly, that weâ€™ve accomplished somethingâ€”even if only pruning our e-mail in-boxes. Unfortunately, current research indicates the opposite: multitasking unequivocally damages productivity.
