Business Insiders stats don't match they original study they refer to...
Quote from FDU.edu
"The study showed that the effects of ideologically pitched media, like Fox News, MSNBC and talk radio, depend on who is listening or watching. On the whole, MSNBC, for instance, had no impact on political knowledge one way or the other. However, liberals who watched MSNBC did better on the knowledge questions, answering correctly 1.89 of the domestic questions and 1.64 of the international questions correctly. Similarly, while moderates and liberals who watch Fox News do
worse at answering the questions than others, conservatives who watch Fox do no worse than people who watch no news at all. Talk radio also had differential effects depending on the ideology of the listener, but they were much smaller. None of the other news media had effects that depended on ideology."
