My post was in no way meant to be exhaustive but it's good to know that since you failed to list any of my other shortcomings in life that you believe me to be otherwise perfect. Afterall, you failed to list all of my failures so you must be assuming they don't exist.

My reasoning was that if you thought it were the norm, it wouldn't be worth mentioning. And you talk about it as a 'most interesting' example so it seems unlikely you didn't consider it an anomaly.

they mentioned that

OP mentioned one error and the resulting policies because of it, I didn't see any others he mentioned. I don't think it's reasonable to know how many policies are determined based on sound data and processes, and how many are so politically motivated that nobody ever checks the numbers. You really only find out by happenstance when someone checks on a lark. We could make a concerted effort to verify everything, but where would you even begin for policies that have already existed for decades?
