(AP Photo/Jacquelyn Martin) (Newser) – Surprise, surprise: Turns out it's not a good idea to use Facebook while studying. A new study finds that those who did so scored an average of 20% lower on exams than those who did not, the Telegraph reports. However, only one-quarter of those who used Facebook while working believed the multitasking had a negative impact. The study also found that students who did not use Facebook spent 88% more time studying than those who did. "While people may think constant task-switching allows them to get more done in less time, the reality is it extends the amount of time needed to carry out tasks and leads to more mistakes," says the professor who ran the study.
