Engineering purpose: Raise the bar for certain especially important decisions.

How it works:

• Constitutional amendments: 2/3 of both houses + 3/4 of states
• Veto override: 2/3 of both houses
• Treaty ratification: 2/3 of Senate
• Impeachment: 2/3 of Senate (after House majority)

Why this promotes good ideas:

1. Preventing rash changes: Easy to pass laws with 51%, but fundamental changes need broad consensus
2. Forcing deliberation: Achieving 2/3 or 3/4 requires extensive coalition-building and compromise
3. Stability: System can't be easily changed by temporary majorities
4. Strong signal: If 2/3 agree, likely a genuine consensus not partisan victory

Modern engineering analog: Critical safety systems require multiple confirmations before activation (nuclear weapons, emergency shutdowns). High-consequence actions need high certainty.

What the Founders would add today: Different supermajority thresholds for different types of decisions based on reversibility and impact; emergency procedures with post-hoc review; sunset provisions for major legislation.
