Re: We hear these stories all the time
"Discrimination is something which we are all guilty of"
It would be very boring if we all had the exact same opinions, and it would be hard to navigate the world without the ability to "tell 'things' apart".
Now, incorrectly categorising negative behavioual attributes, or social status, or whatever - due to a low sample size/measurement error/invalid theoretical frameworks.... that I agree is sloppy analysis and we should educate ourselves.
Guilt has nothing to do with it being wrong - sounds very American/puritan to me.
Cheers, homo sapiens!
