alt Hacker NewsI work in adtech. We actually had to mangle some of our analytics data because it didn't match the broken data a client was used to. Our data was more accurate, but because the numbers didn't match the other analytics suite the client used, so we had to make it worse.
I wish I was joking.
I work in HR. We had to mangle our salary analytics stuff because it kept suggesting that clients should pay more to attract talent. Like most employees in the same sector and position were being paid more that what they wanted to pay and that meant our analytics were wrong.
