From all the corporations that control so much of our lives, the government, science, medicine, religion. Every major institution in our society. Every message has to be carefully parsed and squinted at, one always has to deduce what might have been the (truthful, real, honest) conversation behind closed doors that produced what we're hearing or reading.
From every message it is possible to know only one thing: what the author wants us to think. What is real is almost always another story.
That is tiresome.
