Here is a true story, from my memory of about 25 years ago. I worked then in Risk Dept of a big international securities company with NY headquarters in WFC, next to the Wall Street. The risk calculations kept showing that a risk of some investment that the management wanted to make, was unacceptably high. But the management wanted it really hard. So we, the financial and the system analysts of the Risk Dept, have spent hours adjusting parameters until the risk came down just below the threshold for the management to justify the deal. The deal went through. A few weeks later, the crash of 1998 happened. The company lost a lot of money. The management was fired. The analysts got big bonuses anyway.
