A think tank is just a fake university run by conservatives or neoliberals to confuse people. Look at this for instance.
The chap spreading the wrong about Obamacare is an “adjunct scholar” at the American Enterprise Institute.
In other words he is supposed to appear a part-time, innocent eager beaver pursuing truth. Whereas his fee for the “research” alone is probably double or triple what an actual adjunct professor would be paid for teaching one class.
