A pet peeve (HAR!!!): computer geeks and statistics experts reducing complex issue into “simple” charts and graphs that have apparent credibility because of their form rather than their substance. I encounter this seductive form of fake erudition—“You can’t argue with statistics!”—in every field I explore: baseball, politics (Sorry, Nate Silver), social science, science (climate change models are a spectacular example), education. “Simple, straightforward” arrays of statistics that hide biases, dubious assumptions, projections, value judgments, undisclosed definitions, and who knows what else are presented to persuade on the false representation that they are “hard” representations of fact.  Very frequently, they are not, and when they are not, they incompetent, irresponsible and dishonest.
