“The second way switching harms your attention is what we might call the screw-up effect. When you switch between tasks, errors that wouldn’t have happened otherwise start to creep in, because – Earl explained – ‘your brain is error-prone.

Glitches start to occur. ‘Instead of spending critical time really doing deep thinking, your thinking is more superficial, because you’re spending a lot of time correcting errors and backtracking.”

“Focus, damn you. I thought back to this moment when, over a year later, I interviewed Professor Gloria Mark, who has spent years studying the science of interruptions. She explained to me that if you have spent long enough being interrupted in your daily life, you will start to interrupt yourself even when you are set free from all these external interruptions.”
