Heatmaps without theatre: three calibration drills

Heatmaps are persuasive visuals—and easy to misread when they stand alone. We use three calibration drills in the Taean desk sessions so teams connect color blobs to decisions. First, duplicate the view for mobile and desktop with identical color scales so conversations do not mix apples with oranges. Second, overlay two segments that should behave differently; silence in the diff is as informative as drama. Third, pick one surprising cold spot and assign a five-minute silent observation clip before jumping to solutions. These drills do not replace experiments. They stop teams from painting entire pages red off a single aggregate view. The output is a tighter list of falsifiable questions. Try the sequence on a page you think you know well; the segment diff alone usually surfaces an assumption nobody had articulated aloud.
