Decision Making
Strong Opinions, Weakly Held
Commit to a confident first guess, then attack it. Trade the paralysis of waiting for complete data for a fast cycle of forecast and refute.
The Promise
Reach a useful judgment faster by committing to a confident first guess and then attacking it, trading the paralysis of waiting for complete data for a rapid cycle of forecast and refute.
How It Works
- Make the tentative forecast first. State it with conviction, on whatever information you already have.
- Invert and hunt for the misfit. Look for the data point that doesn't fit and the reason you might be wrong.
- Feed what you find back in. Revise the forecast and run the loop again. A sequence of rough guesses, each ruthlessly tested, arrives at a good one fast.
In Practice
A reader revising a plan mid-quarter states a confident read on what has changed, then deliberately looks for the evidence that would prove the read wrong. The willingness to be wrong out loud is what keeps the plan current instead of defended.
