Weber's Law states that the difference threshold, or the minimum difference that must exist between two stimuli in order for the difference to be detected, is proportional to the magnitude of the stimuli. In this case, the difference between Hans's original weight and the added weight was 4% of the original weight, while the difference between Franz's original weight and the added weight was only 1%. Since the difference threshold is smaller for larger stimuli, this is consistent with Weber's Law.
