Bias is a nasty beast. A market research class I took in graduate school focused on the identification and elimination of bias. My final paper was on an intentionally biased piece of research. It was far easier to introduce bias and then talk about the bias than it would have been to attempt to do unbiased work and defend it as unbiased.
For that reason alone, the Trump administration’s recent complaints that Google’s search engine is biased are almost certainly true.
