There’s a tell. It usually comes early in a conversation, before the idea has even fully landed. It sounds like: “We’re not doing that.” “That’s not how we operate.” “We’ve already decided.”

No pause. No question. No curiosity about where the idea might go. That’s not a response. That’s a drawbridge going up.

I look for collaborators who bring ideas to the table and challenge what’s already there, because that’s what I do, and it’s the only kind of dynamic that generates anything worth building. So I pay attention to how people receive a new idea in the first thirty seconds. Not whether they agree with it. Whether they’re willing to stay in the room with it.

Recently, I brought an idea to a potential collaborator. Something I thought could meaningfully improve the customer experience of what they are building. Before I’d finished, the door closed. Not rudely, just firmly. We’ve already decided. That’s not the direction we’re going.

Maybe the idea was wrong. That’s beside the point.

The moment someone shuts down exploration before understanding what’s being explored, they’ve communicated something more important than their opinion on the idea: The answer matters more than the conversation.

And once that’s been said, even without words, something shifts. I didn’t bring the next idea forward. Not out of spite. There was simply no signal that the ground was safe to build on. You don’t keep planting where the soil has already been declared closed.

What people who block ideas early rarely understand is what they’re actually protecting. They think they’re protecting focus, or momentum, or a decision that took months to reach. What they’re actually protecting is the comfort of not having to reconsider. The idea isn’t the threat. The openness required to hear it is.

I’ve walked away from collaborations for exactly this reason. Not because my ideas are better, they’re often not, but because the moment a partner signals they’re done exploring, they’ve also signaled they’re done growing. And organizations that are done growing are just executing a slow exit.

The question isn’t whether you’re open-minded in principle. Everyone is, in principle.

The question is what happens in those first thirty seconds when something unexpected lands on the table. Do you reach for it, or do you reach for the door?

Bottom line: Being open-minded is a superpower. It’s something I look for in potential employees and collaborators because it’s the foundation for curiosity and innovation. Ask yourself: Am I inviting or blocking ideas?
