Why does one rejection have the power to override dozens of wins? Why does your brain cling to the time you were told you're not good enough — and quietly use that story to limit what you try next?

In this episode of My Rejection Story, Alice is joined by Anne-Laure Le Cunff (neuroscientist and author of Tiny Experiments) to explore how the negativity bias shapes our response to rejection, why the brain's survival wiring keeps us playing small, and how tiny experiments can help us break free.

Anne-Laure explains the neuroscience behind brain negativity bias: your brain records negative experiences with far more weight than positive ones because in ancestral environments, rejection meant being cast out of the group, which meant death. This negative bias psychology made sense for survival, but in modern life the negativity bias quietly convinces us that raising our hand or trying something new is a threat worth avoiding. She also introduces the self-consistency fallacy — the belief that because you've always been a certain way, you must continue that way. This negative cognitive bias narrows possibility and keeps us stuck.

If you've seen Anne-Laure Le Cunff's TED talk or her Anne-Laure Le Cunff Big Think appearance, you'll recognize the themes — but this conversation goes deeper into the personal fear behind the framework. Anne-Laure shares her own story of leaving Google after a health scare, launching a startup for the wrong reasons, and finding liberation when it failed. That failure became the catalyst for everything that followed, including Tiny Experiments by Anne-Laure Le Cunff.

Together they explore how to stop negativity bias from running your life — not through willpower, but through curiosity-driven experimentation and metacognition. They discuss why big goals often backfire, why tracking metrics without tracking how you feel is a trap, and how negative attribution bias causes us to internalize rejection as proof of unworthiness rather than information. Anne-Laure Le Cunff's tiny experiments framework offers an alternative: small, time-bound actions evaluated through honest reflection on both external results and internal experience. This is overcoming negativity bias not by fighting your brain, but by giving it new data.

In this episode they explore:

• How the negativity bias developed as a survival mechanism and why it backfires today
• The self-consistency fallacy and how past rejection becomes a limiting identity story
• Why you cannot rationalize your way out of fear and what actually works
• The neuroscience of exposure therapy and rewiring brain negativity bias
• Anne-Laure's journey from Google to burnout to building Ness Labs
• Why big goals trigger the arrival fallacy and social comparison
• How metacognition makes experiments meaningful
• Intentional imperfection and communicating your limits to prevent burnout
• The difference between toxic productivity and mindful productivity
• This episode is an invitation to stop letting the negativity bias write your story. Your brain's job is to keep you safe — your job is to decide whether safe is enough.
