How do separate bias from truth? If I said more asian people are smarter than white people I am biased and racist. If I said more asians have black hair than white people I am not biased, I'm stating an objective fact. The only fundamental difference between the two statements is that there are hard numbers lending support to one statement (asians having black hair) and the other statement does not. Neither statement, from a technical standpoint, can be verified definitively. To build a machine that identifies whether or not a statement is biased one must first build a machine that identifies whether or not the underlying statement is true or false. Building such a machine is an impossible endeavor because the means in which we identify whether or not something true or false is through data, a source which in itself can be biased.
