Ugh, I hate it when people do things like Exhibit 4 [0] - the size and coloration of the boxes does not match the numbers for the bottom two figures (with the lower-right quadrant in both being displayed as larger than the upper-right, despite having a lower number).
Lies, damned lies, statistics and misleading figures.
Mutually Exclusive & Comprehensively Exhaustive. It's how to do bullet points according to McKinsey. They had to invent it in the 1960s because apparently by the 1960s no one at McKinsey was yet, you know, aware of the existence of centuries' worth of literature on formal logic. So they reinvented the wheel as far as that particular cultural achievement was concerened. Or the first millionth of it, to be more precise, and left it at that, because the rest of it would have no longer fit onto a single PowerPoint slide.
Alternatively, this is just some guy asserting that everyone at McKinsey thinks they invented a brand new concept, when in fact, it’s just a heuristic they teach people to communicate more effectively, because communication is hard.
Lies, damned lies, statistics and misleading figures.
