We tend to think the problem is the behavior.
Drinking too much.
Scrolling too often.
Snacking late at night.
But what if those behaviors aren’t the problem. . .
and are actually the solution?
In this Lab Notes episode, I reflect on my conversation with Erica Mallery and unpack a powerful mindset shift:
• These habits exist because they reduce discomfort
• And your brain is wired to repeat what works
From a neuroscience perspective: discomfort activates the amygdala (our "fight or flight" brain region), and under stress, the prefrontal cortex (which helps regulate the amygdala) becomes less effective; together, this leads us to default to familiar, reliable relief.
That’s where habit loops form.
And that’s why trying to “replace” a problem behavior often fails.
We're trying to replace a behavior that's actually working for us in the short term.
Instead, real change comes from building your ability to sit with the discomfort that remains once you remove the coping mechanism.
In this episode, I walk through:
• The neuroscience of habit loops and negative reinforcement
• Why modern life makes discomfort easy to escape
• How “extinction learning” reshapes your brain’s response
• A simple, practical way to start (30–60 seconds at a time)
Try this today:
• The next time you feel discomfort, pause.
• Stay for 30 seconds.
• Notice what happens.
You’re not doing nothing.
You’re training your brain.
