What is adult peer pressure?

Adult peer pressure is a concept in personal epistemology: Social conformity pressure does not disappear after adolescence — it just becomes more subtle.

Example: Your friends all buy houses in their early thirties. You are happy renting — it gives you flexibility, lower costs, and time for work you care about. But at every dinner party, someone asks when you are buying. Nobody tells you to buy a house. Nobody threatens consequences. But after eighteen months of the question, you start browsing listings. Not because your reasoning changed. Because the ambient pressure made your position feel like a deficiency rather than a decision. The conformity mechanism is identical to the one that made teenagers wear the same shoes — it just wears a blazer now.

This concept is part of Phase 37 (Autonomy Under Pressure) in the How to Think curriculum, which builds the epistemic infrastructure for autonomy under pressure.
