Belief Audits: Check Your Assumptions

You may have spent years (or even decades) building your expertise. But is any of it still relevant? And how much of it is an active detriment to your startup?

In this special solo episode, Yaniv Bernstein delivers a no-guest monologue on the most critical skill any founder can develop right now: ‘unlearning’. Drawing on Morgan Housel's ‘Same as Ever’; real-world examples from his own startup, Vera; and frameworks for rebuilding beliefs from the ground up, Yaniv makes the case that obsolete knowledge is as bad as radioactive waste actively distorting your decisions.

In this episode, you will:

• Understand why AI is making the half-life of expertise shorter than ever before
• Learn how the sunk cost fallacy stops founders from discarding knowledge that’s causing more harm than good
• Discover why the identities you've built around your craft ("I am a programmer", "I am a copywriter") may be the single biggest barrier to adapting in 2026
• Find out what skills are actually worth holding onto, and how to combine them with the meta-skill of rapid adaptation
• Learn three practical mental models for unlearning: belief audits, first principles thinking, and systems thinking
