Let’s see some more example of data collection and model design not being objective:

1. We see that cars are safer for men than women because the crash-test dummies are men.
2. We see that cars are safer for thin people because the crash-test dummies are thin.
3. We see drugs are safer and more effective for white people because blacks are underrepresented in clinical trials (which is a whole other story about power and data collection in itself).
4. We see that Polaroid film used to only pick up white skin because it was optimized for white people.
5. We see that poor people are uninformed by definition of how we take opinion polls (read the fine print).
