“When you switch your brain to a new “thread,” a whole complicated mess of neural activity begins to activate the proper sub-networks and suppress others. This takes time. When you then rapidly switch to another “thread,” that work doesn’t clear instantaneously like electrons emptying from a circuit, but instead lingers, causing conflict with the new task.
To make matters worse, the idle “threads” don’t sit passively in memory, waiting quietly to be summoned by your neural processor, they’re instead an active presence, generating middle-of-the-night anxiety, and pulling at your attention. To paraphrase David Allen, the more commitments lurking in your mind, the more physic toll they exert.
This is all to say that the closer I look at the evidence regarding how our brains function, the more I’m convinced that we’re designed to be single-threaded, working on things one at a time, waiting to reach a natural stopping point before moving on to the next.”
