Second-Order Thinking
Follow consequences past the first, obvious result to the results that result from it.
And then what?
Reach for it when
- A decision is hard to reverse: hiring, pricing, policy, moving, investing.
- The first effect looks great and everyone is cheering.
- You’re setting a rule, target or incentive for other people.
- A quick fix is tempting for a problem that keeps coming back.
- Other people or competitors will react to what you do.
Put it down when
- The choice is small and easily undone. Just try it and see.
- You’re spiralling into endless “what ifs” and not deciding at all.
- The effects are too far out to predict usefully. Build in checkpoints instead.
The framework
- State the decisionOne clear sentence. What exactly will change?
- List first-order effectsThe immediate, direct results, good and bad.
- Ask “and then what?” for eachTreat each effect as a new cause. Go at least two levels further.
- Widen the circleWho else is affected? How will customers, rivals or family respond?
- Check the time horizonDoes it look different in 10 days, 10 months, 10 years?
- Decide and add safeguardsGo ahead, change the plan, or protect against the worst branch.
Rules of thumb
- Good now, bad later is common. So is bad now, good later.
- When you reward a measure, people will optimise the measure, not the goal.
- Every action invites a reaction. Assume others will adapt.
- Most of the value of thinking ahead comes from the first two levels.
Questions to ask yourself
- And then what?
- Who else does this touch, and how will they respond?
- What will this look like in a year?
- What would I be rewarding, really?
Common traps
- Stopping at the first, pleasant effect.
- Assuming everyone else will stay still while you change.
- Analysis paralysis: mapping forever instead of deciding.
- Treating predicted effects as certain. They are guesses, so watch for them.
