If there is money or politics involved in anything the experts are talking about I tend to not believe them. It seems these days that most people have an alternative motive for anything they say and the experts are actually experts at showing only the data that supports their claims not necessarily experts on the topic at hand. Take Bill Nye the science guy for example. Dude has an undergraduate degree in Engineering and had a popular science show for kids like 20 years ago.... but he is regularly called upon as an expert for everything from biology to astrophysics while not having a level of expertise in really anything he talks about.
