Breaking bad habits often feels like a test of willpower. We tell
ourselves we’ll stop scrolling, eat better, or exercise more —
and then fall right back into the same routines. So why is
lasting change so hard?
As part of our spring cleaning series, we’re revisiting a
powerful episode from The Happiness Lab archives that reveals a
surprising truth about behavior change: it’s not about willpower
at all. Dr. Laurie Santos sits down with psychologist Wendy Wood
to explore what the science of habits really says about why we
get stuck — and how we can finally change.
Along the way, we hear the remarkable story of American soldiers
in Vietnam who abruptly overcame heroin addiction after returning
home, offering a powerful clue about how habits really work. If
you’re looking to break a bad habit or build a better one, this
episode shows how small changes to your environment can make
lasting change feel almost automatic.
