Why Your Brain Defends Decisions That No Longer Fit
Episode Overview
- The brain often defends past decisions by seeking evidence that supports them, even when circumstances have changed.
- Cognitive dissonance creates discomfort when a decision no longer fits how you see yourself, leading to self-defence instead of honest evaluation.
- Choice-supportive bias can cause memories to favour the option chosen and make rejected options seem worse over time.
- Treating decisions as hypotheses allows you to update them as you gain new information, without judging your past self.
- Asking if a decision still fits the life you live today can open up space for change without seeing it as failure.
“Changing your mind doesn't always mean you were wrong. Sometimes it simply means you know something now that you didn't know then.”
Curious about how others navigate their sobriety journey? This short Think Thursday instalment from The Alcohol Minimalist Podcast zooms in on one surprising obstacle to change: the way your brain clings to past decisions, even when they no longer fit your life. Molly Watts talks about those moments when you keep defending a routine, a goal, or even a drinking habit that deep down doesn’t feel right any more.
She breaks down concepts like cognitive dissonance and choice-supportive bias in plain language, showing how the brain hunts for evidence that keeps old choices looking good. As she puts it, “Changing your mind doesn't always mean you were wrong. Sometimes it simply means you know something now that you didn't know then.” You’ll hear about classic psychology studies where people rated products more highly once they’d chosen them, and remembered their favourite option more positively than the one they rejected.
Molly connects this to everyday beliefs such as “I’m not athletic” or “I need pressure to get anything done” – labels that can quietly shape behaviour long after your circumstances have changed. Rather than shaming past decisions, Molly suggests treating them like hypotheses that suited a particular time in your life.
Her gentle humour (including a nod to reconsidering that haircut from 1987) keeps the science accessible, while her questions help you apply it: if you were choosing today, would you make the same decision? What evidence are you ignoring because it doesn’t match the story you’ve always told yourself? For anyone re-thinking their relationship with alcohol, routines, or identity, this episode offers a calm, brain-based reminder that updating your choices can be a sign of growth, not failure.
So what’s one decision or story about yourself you’re ready to ask: “Does this still fit the life I’m living now?”
