I've also seen multiple people build models that reflect the data collection instead of the biologic/medical process, and present it without even realizing how wrong their results are. The problems in these cases is often their "objective" measures of performance (e.g., precision, recall, accuracy, AUC, whatever) look pretty good, but they don't see that it's because the model AND data are both heavily influenced by this larger problem.
This is great. It's something I notice I have to mentor my junior data scientists and ML practitioners on with some regularity. Data science and machine learning aren't necessarily useful without some additional domain knowledge and discipline to recognize the need to view the data from many different perspectives and with many different relationships highlighted. Too often they see high P/R numbers and call the job done, or something similar.
