With a name like empath, I'm compelled to wonder if what you're maybe suggesting is not that they remove their biases, but rather that they apply their own biases in order to achieve a more desirable outcome in accordance with their contextualization of the data and desired outcomes.

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.
