I've been elbow-deep in probabilistic marketing research, and I hit one of those thoughts so obvious I assumed everyone already knew it. Then Scott McKinley, the CEO of Truthset, sat me down and walked me through how this stuff actually works, hop by hop, and I stopped assuming anybody knew anything. We are not naming the bad guys today. Not because we're being polite, but because there are too many of them to name in one column, and picking one lets the other forty off the hook.
