This is a classic example of a study in the social sciences that confirms my prejudices, but whose actual methodology is almost entirely meaningless. The participants are not asked to make any consequential decision based on the information, but just to fill out a survey saying whether they believed the claims. A nudge-conomist would say that even though people have stated preferences, their acted-upon preferences can diverge, so this study proves nothing. Even though I'm disposed to believe that nudges like this do create "nudge fatigue" and that people rapidly become immune to it (like the $*.99 pricing model), this study does nothing to confirm or dispute that notion.
