Matthew sparked a lively discussion last week on the use “of widely-repeated . . . statistics” that are in fact “unreliable guesstimates misrepresented as precise calculations—and at worst, completely bogus” in discussions about corruption. He cited the claims that “$1 trillion in bribes are paid annually” and that “corruption costs the global economy $2.6 trillion per year” as examples. The former, a wild guesstimate, and the latter not even that are routinely accepted as fact in media accounts and policy notes issued by development agencies and appear even in papers purporting to be serious academic works. I do not link to examples for two reasons. One, there are so many that I would have to choose which ones to cite, and I don’t want to be accused to playing favorites. Second, the links would embarrass the guilty by calling them out. But many readers will know of whom I speak, and those who don’t can easily compile a list of offenders thanks to the magic of internet search engines.
I think Matthew did those concerned about combating corruption a great service by prompting debate about the use of such numbers, and I applaud him and those who replied for moving the discussion forward. At the same time, I fear Matthew may have inadvertently pushed the discussion off-track with his observation in the opening paragraph that “in the grand scheme of things, made-up statistics and false precision are not that big a deal.” I say this because, in responding to Matthew’s post, readers focused on a single issue: how much help it can be in discussions about controlling corruption to throw around phony numbers.
If the only question were whether what can fairly be termed a “wild ass guess” about the extent of corruption or some type of corruption or the losses it causes or what-have-you is if it helps advances policies that will help stamp corruption out, then Matthew is right; “made-up statistics and false precision” aren’t a big deal. But suppose WAGs, by which I include both unsupported guesstimates and bogus numbers, are harmful too? That not only are they sometimes useful by drawing attention to the issue or prompting action, but that sometimes they retard the cause of combating corruption. Then what?
Below are two ways corruption WAGs can be harmful and a modest proposal for lessening that harm without calling a complete halt to their use. Continue reading
