7 Ways Your Brain Sabotages You (And What to Do)

Dean Burnett’s The Idiot Brain is the funniest neuroscience book I’ve ever read, and the most useful for one reason: it convinced me my brain is buggy by design, not because I’m uniquely broken. Here are seven of those bugs as they show up at work, plus the fix.

Your memory is reconstructive, not playback. You don’t remember meetings. You re-create them, with editorial bias. Fix: write things down within the hour. Trust paper, not your recall.

Your attention is built for motion, not stillness. Static screens lose. Notifications win, every time. Fix: put movement into your work. Walk between blocks, stand up between calls. You’re not “easily distracted.” You’re a body.

Your motivation system is anchored to social comparison whether you like it or not. You think you want the project; you actually want to not be the one who didn’t ship. Fix: pick comparison sets on purpose. Curate who you see working.

Your stress response treats deadlines like predators. Cortisol doesn’t know the difference between a tiger and a Tuesday review meeting. Fix: stop fueling it with caffeine on the worst days. Your nervous system is already loud enough. I wrote more about that in stress management for people who can’t just breathe through it.

Your decision-making degrades faster than you think. Burnett’s data suggests cognitive quality drops noticeably after three or four substantive decisions in a row. Fix: front-load the hard ones. The same logic behind books about decision-making when the stakes are high. Don’t decide rates, scope, and hiring in the same hour.

Your brain rewards finishing more than progress. You’ll stay up to close one tab and ignore the project that’s two weeks behind. Fix: end the day on a hard task half-done. The discomfort pulls you back tomorrow.

And the meanest one: your brain genuinely believes you are average at most things and exceptional at one or two. That belief is statistically necessary across the population but personally useless. Fix: assume you’re average at the thing you feel sharpest about. You will work harder, and the work will be better. The post on the courage to be average at most things sits next to this one for a reason.

None of this is a character flaw. It’s hardware. You can’t upgrade the hardware. You can stop scheduling your work as if you had different hardware.

That’s the whole post. Now go do something annoyingly small.
