I had a profound realization about journalism in college, when I read a popular science article about what it claimed was some astounding discovery in physics, then when I read the original paper realized that the journalist had taken a single sentence from the abstract completely out of context, misunderstood it entirely, and turned it into a sensational headline. I'm sure it was simply because the journalist didn't have a deep understanding of the principles involved in the paper, and that not all journalism is so far from the mark. But it definitely instilled a skepticism of journalism in me.
