In London's Hyde Park, there's a place called Speaker's Corner, where anyone can preach or shriek anything they like. There have been famous and brilliant people who've made speeches there, and there have been an awful lot of cranks, wackos, and madmen in the park, too. So, how do you tell the difference between a cautionary reporter of impending calamity from a madman off his meds? Too little skepticism risks falling down the rabbit hole into a twisted wonderland of circular logic, but too much skepticism risks overlooking something critical that may become tomorrow's tragic headline.
