I'm not necessarily suggesting that as a bad thing, I just wanted to clarify that it's actually very easy to come up with some very unpleasant data that is totally devoid of bias at all.
Google’s Deep Dream is a great way to visualize this. Given a source image that you repeatedly feed through an algorithm that attempts to parse and recreate the image, an unbiased algorithm would produce something similar to the original. Instead you get dogfishbirds and eyes everywhere — that’s the bias of the training set getting amplified.
About the OP ignorance, well, statistics started off as a social science, so maybe self professed data scientists while looking into social sciences, ethics and psychology, could also look about history.
If you want an example about bias look at Compass and recidivism
