3D UFO "Effects" & Pollution Confound
Rotatable 3D scatter plot: a claimed physiological effect (X), alleged sighting reports (Y) and local pollution (Z, depth) plotted together. Slice a thin band along the pollution axis and watch the effect-sightings correlation collapse to near zero — the confound made visible in three dimensions.
The same claimed physiological effect and alleged sighting reports from the 2D version, now placed in a real three-axis scatter plot with local pollution as the depth axis instead of a colour hint. Rotate the cloud to see the diagonal streak that a flat, pollution-blind analysis would mistake for a direct causal link — then isolate a thin pollution band with the slice controls and watch that same correlation collapse toward zero. Nothing about the underlying data changes; only how much of it you're allowed to see changes, which is exactly the point a partial-correlation adjustment makes mathematically.
Visualize the relationship in three dimensions to see how removing the influence of a hidden confounding variable collapses the apparent correlation.
