This doesn’t contradict the Thurstonian model at all. This only show order effects are one of the many factors going in utility variance, one of the factors of the Thurstonian model. Why should it be considered differently than any other such factor? The calculations still show utility variance (including order effects) decrease when scaled (Figure 12), you don’t need to eyeball based on a few examples in a Twitter thread on a single factor.
