It’s been a long time but I recall a study featured on Freakonomics where a national park tried different signs to get people to not steal rocks. Signs like, “Taking rocks hurts the ecosystem” and “Taking rocks is a crime.”
The only effective one was something along the lines of, “A million people visit this park every year and leave things alone.” Suggesting that telling people to do the right thing is less effective than peer pressure.
The bar is kind of low these days, so the fact that he doesn’t go lower still somehow makes him better than a large chunk of famous people.
