This scenario illustrates Weber's law, which states that the noticeable difference between two stimuli is proportional to the magnitude of the stimuli. In this case, the noticeable difference in weight between Jim's bag and Giulio's bag is twice as large as the noticeable difference in the number of marbles needed to make each bag feel heavier. This is consistent with Weber's law, which predicts that the noticeable difference in weight will be double the noticeable difference in the number of marbles needed to make each bag feel heavier, given that Giulio's bag is twice as heavy as Jim's to begin with.
