Decision-making scenario MATLAB user interface. After reporting an initial sampling strategy to the experimenter using the diagram of the dune cross-Sect. (22 possible locations, up to 10 measurements at each location), participants plotted their measurement data one location at a time by pressing the “Continue” button. Data points appeared in black on the moisture-strength scatterplot (lower left), and visited locations were recorded in text just above the scatterplot along with the number of measurements taken, e.g., Loc1 (× 5). Participants could quit their initial strategy at any point by pressing the “Deviate” button and reporting a new location to the experimenter—data from this location were plotted immediately (in blue). When participants were ready to make a conclusion about the hypothesis they pressed the “Stop” button. The user interface code is available online: https://osf.io/yhpxs/
