From what I’ve read on what people have linked here, she attempted to determine how bad it would be for children spcifficly in aggregate, which is a different question with a potentially different answer.

For decion making, I usused to assume that I could just gather enough facts, and then a single right decision would emerge. And if others made different decisions, they were wrong. We should all try to gather accurate information, but we could still make different decisions or conclusions, and knowing this has helped me to not get decision paralesis at times, and has helped me understand and accept people making other choices than I did at times. One example would be sleep training your child. I will plan to do this, others will not. They are not bad parents for making that choice.
