In short

How failure affects cognition and strategy, arguing that failure can drive neuroplasticity and learning rather than just being something to “celebrate” and move past.

Guests/backgrounds

The transcript features a brain-coach researcher who served as Chris Hemsworth’s brain coach on Limitless with Chris Hemsworth, focused on neuroplasticity and insulating brains from aging.

Key claims

Failure signals the brain that the current system isn’t working, prompting rewiring; failing triggers neurochemicals that support growth and learning. In organizations, company failure can indicate they pushed ambitious limits and generated lessons that prevent repeat mistakes.

Notable examples

Chris Hemsworth’s Limitless series; organizational “failure” as evidence of testing hard, non-easy tasks.

0:49So there's another business trope. We constantly tell ourselves to celebrate failure. That if you're not failing, you're not trying hard enough, and then you need to learn from it, but you need to let go and move on. Does that idea, you know, run from failure, but let go of it and move on, does that resonate with your research? This past summer, I actually served as Chris Hemsworth's brain coach on the show Limitless with Chris Hemsworth. And it was all about exploring neuroplasticity and how we can insulate our brains from some of the negative effects of aging. And one of the biggest lessons to come from that TV series is the importance of challenging yourself enough that you do fail.

1:30And that's because it's only when we fail that we send a signal to our brains that this current system's not working, that the brain needs to rewire itself in order to achieve the task. And that's how you tap into the brain's capacity for neuroplasticity and how you keep strengthening it and boosting it over time. And so when we fail at something, our brains release this really powerful cocktail of neurochemicals that really help drive growth and learning. And so I think, you know, it might be more of a metaphor in the organizational context, but I absolutely believe that when a company fails, think about all the lessons they're learning, all the mistakes they won't repeat, and also the fact that they tried something hard, right?

2:13We often don't fail at easy stuff. And so it can be an indicator that a company was really pushing the limits and testing out something very ambitious.

2:48Tap to listen now to Snap Judgment from KQED on Spotify. Some personality quirks are really funny. Like, I talk to my left foot more than I talk to my right. You know what's not funny and not a personality quirk? OCD. Although the term OCD is widely recognized, it's misunderstood by most people. It doesn't mean being tidy or clean. It's having obsessive fears, thoughts, and urges. You question your character. You question your safety. That's OCD. Breaking the OCD cycle takes effective treatment. Go to NoCD.com to learn more.

We love to say “celebrate failure”—but here’s the science behind why it actually helps you grow. Failing is how your brain learns, rewires, and gets stronger.
