Ford, Kavanaugh, and Probability

I must begin by quoting the ever-quotable Theodore Dalrymple. In closing a post in which he addresses (inter alia) the high-tech low-life lynching of Brett Kavanaugh, he writes:

The most significant effect of the whole sorry episode is the advance of the cause of what can be called Femaoism, an amalgam of feminism and Maoism. For some people, there is a lot of pleasure to be had in hatred, especially when it is made the meaning of life.

Kavanaugh’s most “credible” accuser — Christine Blasey Ford (CBF) — was incredible (in the literal meaning of the word) for many reasons, some of which are given in the items listed at the end of “Where I Stand on Kavanaugh“.

Arnold Kling gives what is perhaps the best reason for believing Kavanaugh’s denial of CBF’s accusation, a reason that occurred to me at the time:

[Kavanaugh] came out early and emphatically with his denial. This risked having someone corroborate the accusation, which would have irreparably ruined his career. If he did it, it was much safer to own it than to attempt to get away with lying about it. If he lied, chances are he would be caught–at some point, someone would corroborate her story. The fact that he took that risk, along with the fact that there was no corroboration, even from her friend, suggests to me that he is innocent.

What does any of this have to do with probability? Kling’s post is about the results of a survey conducted by Scott Alexander, the proprietor of Slate Star Codex. Kling opens with this:

Scott Alexander writes,

I asked readers to estimate their probability that Judge Kavanaugh was guilty of sexually assaulting Dr. Ford. I got 2,350 responses (thank you, you are great). Here was the overall distribution of probabilities.

… A classical statistician would have refused to answer this question. In classical statistics, he is either guilty or he is not. A probability statement is nonsense. For a Bayesian, it represents a “degree of belief” or something like that. Everyone who answered the poll … either is a Bayesian or consented to act like one.

As a staunch adherent of the classical position (though I am not a statistician), I agree with Kling.

But the real issue in the recent imbroglio surrounding Kavanaugh wasn’t the “probability” that he had committed or attempted some kind of assault on CBF. The real issue was the ideological direction of the Supreme Court:

  1. With the departure of Anthony Kennedy from the Court, there arose an opportunity to secure a reliably conservative (constitutionalist) majority. (Assuming that Chief Justice Roberts remains in the fold.)
  2. Kavanaugh is seen to be a reliable constitutionalist.
  3. With Kavanaugh in the conservative majority, the average age of that majority would be (and now is) 63; whereas, the average age of the “liberal” minority is 72, and the two oldest justices (at 85 and 80) are “liberals”.
  4. Though the health and fitness of individual justices isn’t well known, there are more opportunities in the coming years for the enlargement of the Court’s conservative wing than for the enlargement of its “liberal” wing.
  5. This is bad news for the left because it dims the prospects for social and economic revolution via judicial decree — a long-favored leftist strategy. In fact, it brightens the prospects for the rollback of some of the left’s legislative and judicial “accomplishments”.

Thus the transparently fraudulent attacks on Brett Kavanaugh by desperate leftists and “tools” like CBF. That is to say, except for those who hold a reasoned position (e.g., Arnold Kling and me), one’s stance on Kavanaugh is driven by one’s politics.

Scott Alexander’s post supports my view:

Here are the results broken down by party (blue is Democrats, red is Republicans):

And here are the results broken down by gender (blue is men, pink is women):

Given that women are disproportionately Democrat, relative to men, the second graph simply tells us the same thing as the first graph: The “probability” of Kavanaugh’s “guilt” is strongly linked to political persuasion. (I am heartened to see that a large chunk of the female population hasn’t succumbed to Femaoism.)

Probability, in the proper meaning of the word, has nothing to do with question of Kavanaugh’s “guilt”. A feeling or inclination isn’t a probability, it’s just a feeling or inclination. Putting a number on it is false quantification. Scott Alexander should know better.

No More SCOTUS “Swing Vote”? Good!

NOTE: I HAVE UPDATED “U.S. SUPREME COURT: LINES OF SUCCESSION AND IDEOLOGICAL ALIGNMENT” TO REFLECT THE CONFIRMATION OF BRETT MICHAEL KAVANAUGH AS AN ASSOCIATE JUSTICE OF THE U.S. SUPREME COURT.

Justice Elena Kagan — voicing the fears of leftists — says this about the replacement of Anthony Kennedy by Brett Kavanaugh:

I think it’s been an extremely important thing for the court that in the last, really 30 years, starting with Justice O’Connor and continuing with Justice Kennedy, there has been a person who people — found the center where people couldn’t predict in that sort of way. And that’s enabled the court to look as though it was not owned by one side or another, and was indeed impartial and neutral and fair. And it’s not so clear that — I think, going forward, that sort of middle position — you know, it’s not so clear whether we’ll have it.

All of us need to be aware of that — every single one of us — and to realize how precious the court’s legitimacy is….

It’s an incredibly important thing for the court to guard is this reputation of being impartial, being neutral and not being simply an extension of a terribly polarizing process.

So the job of the Supreme Court isn’t to uphold the Constitution, but to find a middle ground between constitutional and anti-constitutional views.

I am hopeful — but not yet certain — that the addition of Justice Kavanaugh to the Court’s lineup will end the three decades of uncertainty praised by Kagan, and that it will put the Court back in the business of firmly upholding the Constitution. A business that it began to abandon in earnest during the New Deal.

Drawing on statistics kept at SCOTUSblog, I have constructed an index of defection (D) for each justice, for the 2005-2017 terms:

D = percentage disagreement (in non-unanimous cases) with members of own wing/percentage disagreement with members of opposite wing.

The wings are the “conservative” wing (Gorsuch, Alito, Thomas, Scalia, Roberts, and Kennedy) and the “liberal” wing (Breyer, Ginsburg, Kagan, Sotomayor, Souter, and Stevens).

The lower the index, the more prone is a justice to vote with the other members of his or her wing; the higher the index, the more prone is a justice to vote with members of the opposing wing. Here’s a graph of the indices, by term:

Kennedy’s long-standing proneness to defect more often than his colleagues grew markedly in the 2014-2015 terms and receded a bit in the 2016 term. His turnaround in the 2017 term restored him to the Court’s “conservative” wing.

Roberts slipped a bit in the 2017 term but was still more in step with the “conservative” wing than he had been in the 2014-2015 terms.

Gorsuch started out strongly in his abbreviated 2016 term (he joined the Court in April 2017). His slippage in the 2017 term may have been due to the mix of cases at stake.

What’s most striking about the preceding graphs, other than Kennedy’s marked departure from the “conservative” wing after the 2010 term, is the increasing coherence (ideological, not logical) of the “liberal” wing. This graph captures the difference between the wings:

The record of the past six terms (2012-2017) is clear. The “liberals” stick together much more often than the “conservatives”. Perhaps that will change with Justice Kavanough on the Court.

Where I Stand on Kavanaugh

As I acquire new information about Christine Blasey Ford’s porous and perjurious memory, I will add links at the bottom of this post.

The cold civil war that rages in America became a bit hotter on September 27, 2018, when Judge Brett Kavanaugh bared his righteous outrage and dared to attack the Democrats who are hypocritically attacking him. Hypocritically? Yes, because Ted Kennedy, Bill Clinton, and Keith Ellison (among many others) have been spared the wrath of Democrats for having committed acts during their adulthood that are far better documented than the charges leveled against Judge Kavanaugh.

Now, Kavanaugh is under attack for having bared his outrage. As if he were not entitled to outrage because, after all, “women must be believed”. There’s a syllogism in there somewhere. It probably goes like this:

Women never lie.

Christine Blasey Ford is a women.

Therefore, Christine Blasey Ford isn’t lying.

That’s a logically valid statement. But, as any respectable professor of logic would tell you, a logically valid statement isn’t necessarily a true statement. The truth of a logically valid statement depends on the truth of its premises. The major premise — women never lie — is prima facie untrue. “Women must be believed” doesn’t pass the smell test.

That’s not to say that sexual assault doesn’t happen. It does, and it should be reported to the police and investigated by the police — as soon as possible after it happens.

Nor do I rule out the possibility that something like the events retailed by CBF happened in 1982. Though there is vast room for doubt given the vagueness and lateness of CBF’s recovered memory, and the lack (thus far) of corroboration by persons she has named as participants in the “party” where she was purportedly attacked. UPDATE: CBF  may soon join the ranks of exposed hoaxers. See this.

If (most of) the Republicans on the Senate Judiciary Committee accept Kavanaugh’s denial of CBF’s allegation, it is only because the Democrats on the committee are bent on convicting Kavanaugh on the flimsiest of evidence, so as to deny the “conservative wing” of the Court a majority.. This is another battle in the cold civil war, which is about control of government and, ultimately, control of our lives. The Republicans, for all of their many faults, are on the side of liberty. The Democrats, for all of their much worse faults, are on the side of oppression. That’s what it comes down to.

In any event, with respect to CBF’s allegation, what is the worst-case scenario? It is that Kavanaugh — as a 17-year-old — did something in a drunken state that he would not have done when sober. What does that have to do with his qualifications for sitting on the Supreme Court if, as seems to be the case, he has never come close to doing something similar in the ensuing 36 years, drunk or sober?

The correct answer is “nothing”. As lawprof blogger Tom Smith says,

a lot of people in positions of high authority are not very nice at all. Some of the Dems on the Senate Judiciary Committee make me want a long, hot shower after listening to them. I care about the environment, so I don’t listen to them. Some of the judges I have known were frankly a**holes, always jockeying for political advantage and not caring deeply about the law. Indeed, we seem to have entered an era in which few people care deeply about the law, attributable mostly it seems to me, and ironically, to law professors. Judge K seems ambitious but to at least care about the law.

In politics, you reach a point, usually near the beginning but almost always by the end, where you have to choose the greater good or the lesser evil. That’s where we are with Judge K. It’s possible he did sexually assault Ford long ago and does not remember it or half-remembers it now. It’s possible Ford has confabulated her memory of this possibly fictional incident. Lots of things are possible. Few lives, except mine of course, could stand up to the sort of hyperpartisan de- and reconstruction that K’s has been subject to. K seems to have been clean as a whistle since at least his graduation from law school. If he was something of a frat boy aggressor while drunk against young women, he seems to have gotten over that a long time ago, if indeed he actually had anything to get over. And yes, I realize this tags me as one of those old white guys who does not think it’s practical to dredge up 30+ year old accusations against an otherwise outstanding-seeming judge in a hyper-political context.

Here’s the bottom line:

But just hypothetically [emphasis added], whom would you choose: a guy who was perhaps, maybe, based on far from ideal memories from 30+ years ago, a heavy drinker and sexual assaulter, but who would uphold the basic structure of the republic, versus another Sotomayor, who is arguendo personally morally upstanding, but who would gnaw obsessively at the pilings under-girding our form of government? Given the choice, I know what I would do.

As the saying goes: Me, too.
