Noam Chomsky argues that, while the US news media are adversarial towards the US government on foreign policy, institutional filters operate to ensure that the criticisms made generally stay within narrow bounds set by the US political elite. Chomsky's research in this area is largely ignored even by academics who agree with this conclusion. The institutional tendency to filter out anti-elite perspectives applies not only to the news media but also to academia. Consequently, Chomsky's work is marginalised due to its emphasis on corporate power, principled opposition to US foreign policy and the role of academia in buttressing elite power.
