(KCEN) -- A new study finds people who multi-task the most are actually the least capable of doing it well, including talking on the phone while driving.
University of Utah researchers measured the perceived and actual multi-tasking ability of 300 college students.
Many who thought they were better than average and therefore multi-tasked more often tended to have the lowest ability scores.
Researchers say frequent multi-taskers can have difficulty focusing on one thing so they get drawn into a second task, like talking on the phone as they drive.
