If you really want to appreciate how we are continuously and ubiquitously misled by a whole range of issues, you just have to pick one topic and investigate that for yourself, in detail, with an open mind. After doing so, the illusionary world immediately crumbles right in front of you, and you can never read any article or listen to any news report in the same way again.
Investigative journalist Sharyl Attkisson, summarises this well in her TEDex Talk below. She describes how astroturf, or fake grassroots movements funded by political, corporate, or other special interests very effectively manipulate and distort media message. And how the information on Wikipedia is controlled.
Sharyl, rather appropriately, discusses this with the aid of the example of a fictitious cholesterol medication.
