What is uncertainty muscle?

The concept of "uncertainty muscle" refers to one's ability to effectively handle and operate under conditions of uncertainty or ambiguity. It suggests developing resilience and adaptability when facing situations where outcomes are unclear or where decisions need to be made without full information.

Shane Parrish discusses how this can be cultivated through an entrepreneurial mindset. He uses the example of job security to challenge common notions about risk, suggesting that taking a job, which seems safe, is actually a risky bet on a single outcome with limited personal control. By contrast, engaging in entrepreneurial activities, despite their apparent risks, may provide clearer insights into the risks involved and can be a way to build this "uncertainty muscle" 1 .
