I'm right and you're wrong!

Quick post: I previously suggested looking out for the confirmation bias in response to the VT shootings, especially regarding gun control. This article, False Lessons from an Atrocity, articulates it better than I could:

It used to be that a shocking act of gun violence would invariably elicit a chorus of demands for tighter gun control laws. How things have changed. Now an episode like that invariably elicits a chorus of demands for tighter gun control laws and a chorus of demands for looser gun control laws. What the reactions demonstrate is that no matter what happens, people are very good at finding confirmation for what they already think. (emphasis mine)
