This is a common mistake people make when thinking about marketing data analysis. It's similar to bits of entropy in browser tracking - the resolution of your screen and the fonts you have installed don't identify you by themselves, but when they're correlated their effectiveness scales much better than human intuition estimates. So you read conservative blogs and listen to Fox News. If Facebook is predicting, for instance, your voting habits, their algorithm won't look only at that. It'll look at where you live, what your job is, the political stances of the people you most associate with, which groups you're a part of and how their members typically lean, what stores you shop at, what search terms you use, and far more metrics than I can list here. Can you honestly say that all of those will point to incorrect conclusions? If you somehow live a live entirely contrary to your internal beliefs you're in a minority so small as to be irrelevant.
