> If a data science team modeled something incorrectly in their simulation, who's gonna catch it? Usually nobody. At least not until it's too late.

Back in my data scientist days I used to push for testing and verification of models. Got told off for reducing the teams speed. If the model works well enough to get money in, and the managers that make the final calls do not understand the implications of being wrong, this would be the majority of cases.
