When entering a new domain, don't feign expertise. Build trust faster by openly admitting "I don't know" and explicitly leaning on stakeholders for their subject matter knowledge. This positions you as a partner who values their expertise, rather than an outsider imposing solutions.

"Expertitis" is a form of the curse of knowledge where one knows too much about a subject to explain it simply to a newcomer. The cure is communication empathy: deliberately stepping out of your own expertise to see and frame the message from the fresh, uninitiated perspective of the audience.

Howard Marks argues that declaring uncertainty is a sign of strength, not weakness. In important settings, saying "I don't know" signals that your ego is in check and thinking is robust. It makes people trust you more, not less, because it shows intellectual humility.

The more people learn about a subject, the more they realize how much they don't know. This contradicts the idea that expertise leads to arrogance. Novices, who are unaware of a field's complexity, are often the most overconfident.

True growth and access to high-level opportunities come not from feigning knowledge, but from openly admitting ignorance. This vulnerability invites mentorship and opens doors to conversations where real learning occurs, especially in complex fields like investing, which may otherwise seem like a "scam."

True connection requires humility. Instead of trying to imagine another's viewpoint ("perspective taking"), a more effective approach is to actively seek it out through questions and tentative statements ("perspective getting"). This avoids misreads and shows genuine interest.

When leading functions outside your core expertise (e.g., product leading tech and data), credibility cannot come from having answers. Instead, it's built by consistently asking open-ended questions to deeply understand the team's challenges. This approach prevents solutionizing and fosters trust.

A young Ed Stack's transparent inexperience in buying meetings didn't lead to exploitation; it invited mentorship. By openly admitting what he didn't know, he transformed vendor relationships into partnerships. People were more willing to help him succeed rather than just sell to him, showing that vulnerability can be a powerful negotiation tool.

Formally trained experts are often constrained by the fear of reputational damage if they propose "crazy" ideas. An outsider or "hacker" without these credentials has the freedom to ask naive but fundamental questions that can challenge core assumptions and unlock new avenues of thinking.
