Reversibility and Commitment

Some decisions are easily reversed; others lock you in. This single dimension—reversibility—should determine how much deliberation to invest. People often get this backwards: agonizing over reversible choices while rushing irreversible ones.

Jeff Bezos calls these Type 1 and Type 2 decisions:

• Type 1 (one-way door): Irreversible or very costly to reverse. Require careful deliberation.
• Type 2 (two-way door): Reversible. Should be made quickly by empowered individuals.

The framework is simple. The application is counterintuitive.

The Mismatch

People often:

• Deliberate extensively on reversible decisions (what to order, what to watch, which email to send first)
• Rush irreversible decisions (major purchases, career changes, relationship commitments)

The pattern is backwards. Small decisions feel safe to deliberate on; big decisions feel overwhelming so we rush to closure.

Why Reversibility Matters

Error Correction

Reversible decisions allow learning. Make a choice, see what happens, adjust. The feedback loop works. Information flows.

Irreversible decisions don't allow this. You commit before you know. Errors can't be corrected; they become permanent.

Option Value

Keeping options open has value. Reversible decisions preserve options. Irreversible decisions eliminate them. Options have positive expected value under uncertainty.

Asymmetric Costs

The cost of a wrong reversible decision = the cost of reversal (usually small). The cost of a wrong irreversible decision = being stuck with the outcome (potentially large).

Identifying Reversibility

Questions to assess:

• Can I undo this? Literally reverse the action?
• What does reversal cost? Money, time, reputation, opportunity?
• How quickly can I reverse? Same day? Months? Never?
• What's the default trajectory? Does inaction also commit me?

Examples

Hiring (Often Treated Backwards)

Hiring is high-cost to reverse (firing is hard, costly, slow). Yet many organizations hire quickly based on interviews, then deliberate extensively on small operational decisions.

Better: extensive deliberation on hiring; fast decisions on day-to-day operations.

Marriage

Legally reversible but costly: financial, emotional, temporal, social costs of divorce. Effectively low-reversibility. Worth commensurate deliberation.

Software Architecture

Some decisions lock in for years (database choice, language, major abstractions). Others are easily changed (variable names, specific implementations). Match deliberation to reversibility.

Lunch Choice

Highly reversible. If you don't like it, eat something else later. Minimal deliberation warranted. Yet people spend significant time on this.

Strategic Implications

Make Decisions Reversible

Where possible, structure decisions to be reversible. Pilot programs. Trials. Phased rollouts. This reduces deliberation cost and enables learning.

Recognize Hidden Irreversibility

Some decisions seem reversible but aren't. Path dependencies. Reputation effects. Sunk cost psychology. Look for hidden lock-in.

Speed Up Reversible Decisions

If it's reversible, decide fast. Analysis paralysis on reversible decisions costs more (in time and opportunity) than occasional wrong choices that get reversed.

Slow Down Irreversible Decisions

If it's irreversible, slow down. Seek more information. Consult others. Consider alternatives. The decision quality matters more.
