1. More than one task splits the brain: study participants were asked to attempt two simultaneous tasks. They made three times the errors when multi-tasking.
2. Practice doesn’t help: In fact, a study of university students found that those who report spending more hours concurrently consuming multiple forms of media (frequent media multitaskers) actually perform worse on tests that assess their ability to switch from one task to the next.
3. You’re not really multi-tasking: research found that you aren’t really doing two things at the same time, you are just moving between tasks.
4. Lost productivity: Multi-tasking results in about a 40% loss in overall productivity.
5. You miss stuff: in a study, 75% of college students who walked across a campus while using their cell phones did not notice a clown riding a unicycle.
6. Music can help and hurt: music helps improve athletic focus and reduces pain, and music allows people to concentrate on a task. However, listening to music while reading and writing impairs memory and performance. If you must, listen to music without lyrics (vocals).
7. Clear to really focus: you’ll make the fewest mistakes, get work done most quickly, and be most productive in an environment free of all distractions.
