The Product Judgment Test

Most PMs think they're good at reading the market. This tool proves whether they actually are.

The Product Judgment Test is a free Excel-based forecasting tracker that scores your product predictions using the Brier Score —the same method used by professional forecasters.

Make predictions. Track outcomes. Get a score. See exactly where your judgment breaks down and what to do about it.

Takes 10 minutes to set up. Pays off every time you make a product bet and shapes you as a leader who is right a lot
