The Burden-of-Proof Trap in Product Decisions

When you require proof of harm before acting, you've already decided in favor of the risk.

I respect your call on this and I'll support it, but want to just say for the record that I don't think it's the right call given the risks. As a parent of two teenage girls — one of whom has been hospitalized twice in part for body dysmorphia — I can tell you the pressure on them and their peers coming through social media is intense with respect to body image. I recognize that my family situation makes me somewhat biased but it also gives me first hand knowledge that most of the people looking at this issue don't have. There won't be hard data to prove causal harm for many years, if ever, but I was hoping we could maintain a moderately protective stance here given the risk to minors. I know these are difficult tradeoffs. I don't minimize the concerns about restricting voice and the internationalization angle. I just hope that years from now we will look back and feel good about the decision we made here. — Margaret Gould Stewart, VP of Product Design

Earlier, Mark Zuckerberg had written: "It has always felt paternalistic to me that we've limited people's ability to present themselves in these ways, especially when there's no data I've seen that suggests doing so is helpful or not doing so is harmful, and that there's clearly demand for this type of expression. I'm generally supportive of finding a way to relax or lift these bans." Zuckerberg subsequently approved "option 2" — lifting restrictions on cosmetic surgery AR effects but not actively promoting them on Instagram.
