What is bright-line rules self-governance?

Bright-line rules self-governance is a concept in personal epistemology: Some drives should have veto power in specific situations — define these in advance.

Example: You negotiated a careful internal contract between your ambition drive and your health drive. The contract was specific, balanced, and well-enforced — work hard during the week, rest on weekends, exercise three times. Then a startup opportunity appeared. Your ambition drive opened negotiations. Your social drive supported it — the team was exciting, the mission compelling. Your security drive raised concerns but was willing to trade stability for equity. Your health drive objected: the role required 80-hour weeks, no exercise, fast food at the desk. It was outvoted, three to one. Six months later, you were in a hospital bed with chest pains at thirty-four. The health drive was right. It should never have been put to a vote.

This concept is part of Phase 39 (Internal Negotiation) in the How to Think curriculum, which builds the epistemic infrastructure for internal negotiation.
