A lot of people these days dont know what bias actually is. For instance they say that Nazis are biased, but humanists are not. Actually both are biased bigots.
What exactly is bias, though? Is it a preference or taste? We all have different preferences and tastes, for instance most of us would rather eat eggs than shit in the toilet. So are we biased against shit?
I think bias is deeper than mere preferences and taste. Actually bias is defined as an aversion and disdain to the process of the scientific method! Bias is not a subjective thing…bias is a mathematical disobedience to the scientifc method, usually arising from a personal prejudice.
For instance, a guy on Fox news doesnt like democrats, so he tries to spin the story using logical fallacies to make them look bad. Or someone interprets neutral data in a way to support their bias. So bias actually has two components…a disobedience to scientific honesty, arising from a personal prejudice.
So can we say that liberals are not biased? Actually, humanists and liberals are quite biased, because they try to state that there is no difference between the races, that all races are the same and we are equal! They use their personal bias to skew the data to compensate for obvious statistical differences! So actually liberals and humanists are biased bigots!
Quite simply bias is simply the act of skewing or distorting the truth to accomodate a personal preference. For example, someone could say that most women are less spatially skilled, but they would not be biased, because they would still potentially hire a woman if she did so happen to be spatially skilled.
Hope that makes it more clear.
