Obligatory joke about the three scientists visiting Scotland in the first time: Biologist: "Whoa, you see that in the distance? That's amazing! All cows in Scotland are brown!" Physicist: "Hold on -- all we know at this point is that there's a population of cows in Scotland that's brown." Mathematician: "No, all we know is, there exists at least one cow in Scotland such that this side is brown." --- With that said, I agree that it's an excessively narrow sample for the kind of conclusion they're trying to draw.
