Wall Street Journal Praises Judicial Ignorance of Statistical Methods

From yesterday's Wall Street Journal editorial page covering yesterday's oral arguments in Gill v. Whitford, a case that involved a challenge to alleged gerrymandering:

[Chief Justice John Roberts] zeroed in on risks for the credibility of the judiciary if the Supreme Court invalidates a state electoral map on purely political grounds for the first time. His reference to EG is to a political science standard offered by the plaintiffs as a test of when an electoral map is too partisan.

. . .

Chief Justice: “It is just not, it seems, a palatable answer to say the ruling was based on the fact that EG was greater than 7%. That doesn’t sound like language in the Constitution.” . . .

[Plaintiffs' Attorney, Paul] Smith: “If you let this go, if you say this is—we’re not going to have a judicial remedy for this problem, in 2020, you’re going to have a festival of copycat gerrymandering the likes of which this country has never seen.

And it may be that you can protect the Court from seeming political, but the country is going to lose faith in democracy big time because voters are going to be like—everywhere are going to be like the voters in Wisconsin and, no, it really doesn’t matter whether I vote.”

Chief Justice: “No, but you’re going to take this—the whole point is you’re taking these issues away from democracy and you’re throwing them into the courts pursuant to, and it may be simply my educational background, but I can only describe as sociological gobbledygook.”

Gerrymanders are unsightly, but worse would be the sight of federal judges becoming political arbiters of every electoral map based on evidence that voters are likely to conclude is itself partisan.

An eye-opening Twitter thread by Steven Mazie illustrating how Chief Justice Roberts and Justice Gorsuch appeared to lack knowledge of the statistical methodology involved paints Chief Justice Roberts' comment as more disturbing than the quippy Editorial Board lets on. While "gobbledygook" is a fun word, reminiscent of "argle bargle" and "pure applesauce" of old, the implications of the comment are that the Court -- the last resort for challenging (often-complex) gerrymandering schemes -- should decline to do so because the methods involved are too complicated and potentially subject to partisan manipulation. Jesse Wegman at the New York Times' editorial page covers Smith's response, which summarizes this problem:

“The problem in this area is if you don’t do it, it is locked up,” Mr. Smith said. “You are the only institution in the United States that can solve this problem just as democracy is about to get worse because of the way gerrymandering is getting so much worse.”

Gerrymanders are more than "unsightly" as the Journal describes. The contorted and bizarre-looking voting districts that gerrymandering creates may result in disenfranchisement of voters along party and racial lines. They threaten representative democracy. The Journal's and Chief Justice's implication that a lack of understanding of statistical methods is enough of a barrier to let this threat go unchallenged is concerning.
