ESP is Real and Science is Broken

So argues an article at Slate.
Having served for a time as an associate editor of JPSP, Bem knew his methods would be up to snuff. With about 100 subjects in each experiment, his sample sizes were large. He’d used only the most conventional statistical analyses. He’d double- and triple-checked to make sure there were no glitches in the randomization of his stimuli.

Even with all that extra care, Bem would not have dared to send in such a controversial finding had he not been able to replicate the results in his lab, and replicate them again, and then replicate them five more times. His finished paper lists nine separate ministudies of ESP. Eight of those returned the same effect.

Bem’s 10-year investigation, his nine experiments, his thousand subjects—all of it would have to be taken seriously. He’d shown, with more rigor than anyone ever had before, that it might be possible to see into the future. Bem knew his research would not convince the die-hard skeptics. But he also knew it couldn’t be ignored....

[F]or most observers, at least the mainstream ones, the paper posed a very difficult dilemma. It was both methodologically sound and logically insane. Daryl Bem had seemed to prove that time can flow in two directions—that ESP is real. If you bought into those results, you’d be admitting that much of what you understood about the universe was wrong. If you rejected them, you’d be admitting something almost as momentous: that the standard methods of psychology cannot be trusted, and that much of what gets published in the field—and thus, much of what we think we understand about the mind—could be total bunk.
Confirmation bias check: I very much agree that most of what we think we understand about the mind is bunk.

UPDATE: This article later made Arts & Letters Daily, which makes me even happier to have mentioned it here first. It's really worth your time, no matter how devoted to science you are or are not. It raises significant questions about the state of our knowledge, and what it means to know what we think we know.

A White Horse is not a Horse


No, not that one. That one's really not a horse. I mean to refer to a philosophical argument from China's Warring States period. The author is somewhat like Socrates, in that he questions the basic uses of language and points out difficulties in how our concepts apply to the world. He is unlike Socrates, if the historians are right, in that he did this chiefly for fun. For Socrates, these philosophical problems were the most important thing in the world -- literally worth dying for, if Plato's treatment of Socrates' defense and death are accurate.

For Gongsun Long, they were a way of entertaining at court. He offered five proofs that 'white horse is not horse.' You can read them all, and a careful analysis of them, at the link above. Here are two of the proofs by themselves, for you to wrestle with before you click through to read the analysis.
Argument 2.
If someone seeks a horse, then it's admissible to deliver a brown or a black horse. If someone seeks a white horse, then it's inadmissible to deliver a brown or a black horse. Suppose white horse were indeed horse. In that case, what the person seeks in those two cases would be one and the same. What he seeks being one and the same is the white one not being different from horse. If what he seeks is not different, then how is it that the brown or black horse are in the one case admissible and in the other inadmissible? Admissible and inadmissible, that they contradict each other is clear. So brown and black horses are one and the same in being able to answer to “having horse” but not to “having white horse.” This confirms that white horse is not horse.

Argument 5.
“White” does not fix what is white.… As to “white horse,” saying it fixes what is white. What fixes what is white is not white. “Horse” selects or excludes none of the colors, so brown or black horses can all answer. “White horse” selects some color and excludes others; brown and black horses are all excluded on the basis of color, and so only white horse alone can answer. Excluding none is not excluding some. Therefore white horse is not horse.
The translation is a bit confusing here. When he says "'white' does not fix what is white," he means that asking for a "white" thing doesn't tell you what kind of thing is supposed to be white. You fix the issue of just what is white not when you specify white, but when you specify the kind of thing you want. This is the same issue that caused Aristotle to divide the world into substances (like horses) and attributes (like being white). So it's not an idle thing to notice; Aristotle hung his basic ontology on the same point.

What Could Possibly Go Wrong?

In fairness, this is exactly why people voted for Donald Trump.
Toby Keith is headed to the Middle East to join President Donald Trump on his trip to Saudi Arabia. The country singer will perform at a free, men-only concert Saturday in the capital city of Riyadh alongside Saudi singer Rabeh Saqer, The Associated Press reported.
Over/under on whether he'll perform this fan favorite?



Before you say there's no way, take a moment to watch this video as well. There's a kind of showmanship at work here.

Gonzo Second Amendment Advocacy

From Joe Bob Briggs:
Hunter S. Thompson used to mail me giant photos of objects being blown to smithereens with dynamite or flung from some kind of skeet contraption so they could be exploded midair, and in most cases he was both the photographer and the destroyer. He would scrawl the precise date and time of the explosion on the bottom of the photo and copy it to the sheriff of Pitkin County, Colorado, who had repeatedly warned Thompson that he was in possession of illegal military ordnance, that he was in violation of pyrotechnic laws, and that he was in imminent danger of jail. As a Second Amendment radical, Thompson wanted to document exactly when, where, and how he had violated the law, then dare the law to do something about it. To me he would just write, “I’m on it.”
Taki's Magazine prefers that you read the rest there, in order to preserve their revenue stream. The rest is a book review of The Kingdom of Happiness: Inside Tony Hsieh’s Zapponian Utopia.

How to Leak Documents: A Primer from the Patriots at the Washington Post

Just in case any of you were thinking of violating your oaths to keep the secrets you swore to protect, here are step by step instructions.

The Comey Memo

This one may really do it.
“I hope you can see your way clear to letting this go, to letting Flynn go,” Mr. Trump told Mr. Comey, according to the memo. “He is a good guy. I hope you can let this go.”…
It's only obstruction if he threatened to fire Comey to get him to drop the investigation, says Richard Painter, George W. Bush’s former chief ethics lawyer; but he went beyond threats and actually fired Comey.

And then he explained why he did: because of this Russia probe.
When I decided to just do it, I said to myself, I said you know, this Russia thing with Trump and Russia is a made up story, it's an excuse by the Democrats for having lost an election that they should have won.... Look, I want to find out if there was a problem with an election having to do with Russia. Or, by the way, anybody else. Any other country. And I want that to be so strong and so good. And I want it to happen. I also want to have a really competent, capable director. He's not. He's a showboat.
He was competent enough to keep memos on his conversations with an unpredictable President, apparently. Or so we shall discover if the Congressional subpoena produces this alleged memo.

Rethinking Gays in the Military

It's been several years now since "Don't Ask, Don't Tell" was replaced with openly gay service. At the time, those of us who were opposed to the repeal worried that introducing sexuality into line combat units would be disastrous for unit cohesion. Military service is rightly conditioned on the needs of the service, without disrespect to those who are excluded for having conditions -- whether blindness or any other condition -- that are not ideal for service.

Our opponents argued that, in fact, asking people to live a lie was too big an ask: they should either be allowed to serve, or not allowed to serve, and realistically with Obama in office that meant they should be allowed to serve.

Some political arguments are about morality, but many political arguments are about forecasting. Once a decision is made and some time has passed, it's possible to go back and examine whether the forecasts were good or not.

On reflection, I think that those of us who opposed the end of "Don't Ask, Don't Tell" were right about the danger of introducing sexuality to line military units, but wrong to think that gays posed much danger here. There just aren't enough gays, as a percentage of humanity, to create that much change. It's not all that likely that a company of infantry will have one gay guy in it; if they have two, that's unusual. There is thus little reason to be afraid that they will pair up, and even if they do, it's really unlikely there will be a third gay in the unit who might become jealous. The argument that it could happen is not wrong, but as a practical matter it doesn't really happen in the kind of small, line units where unit cohesion is of such critical importance.

By contrast, the Marines United scandal shows that the real dangers come from introducing heterosexuality into line units. Even though there aren't that many more women than gays in line infantry units, nearly all the men are subject to feeling attractions and jealousies towards them. There is a serious threat to good order and discipline when the majority of the unit is involved in competing with each other for the sexual attentions of the rare woman; a male/female pair will become the focus of intense jealousy; and if a breakup occurs, you run into an increased risk of photo sharing of the sort that the Marines United scandal is all about.

Since there is apparently no possibility of asking people not to hook up with fellow servicemembers, nor to ask them not to share nude photos of themselves while in the military, we are left with a pretty damaging dynamic to unit cohesion. The military is trying to address it by cracking down on the photo sharing only, which strikes me as a half-measure that won't be effective because it doesn't begin to treat the emotional issues that are really at work. Young people have higher hormone levels and less experience, and they are easily swayed -- we all remember how easily from our own youth -- by longing and loneliness and jealousy.

Consider too that those high hormone levels, in the form of testosterone, are even helpful for the basic mission of the infantry. Yet insofar as these same high levels make one more likely to make bad love-related decisions that will now result in a mandatory separation review, it sounds as if the introduction of sex to the infantry really is proving disastrous. Not only are these units cracking up over the sexualization of fellow soldiers or Marines, the chosen solution is likely to expel chiefly those whose hormone mix best supports battlefield performance.

So, we were right about the sex. We were wrong about homosexuality, though. It's too uncommon to be the kind of problem we thought it might be. Rather, heterosexuality is the real danger to the military's unit cohesion.

Brief Thoughts on Constitutional Interpretation in a Common Law System

It occurred to me the other day that a lot of Tea Partiers and other sundry and assorted Conservative types tend to treat the US Constitution as if it were in a civil law system rather than a common law system.

In a civil law system, when a judge or court makes a decision, it does not set a precedent that binds future judges or courts. All a court has to look at are the statutes in question and the facts of the case. This is similar to the old "What part of 'shall not be infringed' do you not understand?" rhetoric I've heard many times in discussions of the 2nd Amendment.

Stare decisis, or precedent, is an essential feature of common law systems like ours, which we inherited from the English. You can't just look at the law and the facts in a common law system. You must also look at precedents set by previous courts. As a result, we can't just read the text of the Constitution itself to understand what is and is not constitutional.

Although I think the system we ended up with was brilliant, I personally think the Founders messed up when it came to the judiciary. They have become a rolling constitutional convention because of the role of precedent. I have thought quite a bit about how to solve that problem, but maybe a simple solution would be to strip USSC rulings on the Constitution of precedent.

Of course, I am not a lawyer. I don't even play one on TV. My suggestion would probably wreck the whole system and bring about the Fimbulwinter and eventual Apocalypse. But if you ignore that, it's kind of an interesting idea.

An Amusing Error

Rebecca Tuval and Philosophy's Existential Crisis

Oliver Traldi, a writer with an MA in philosophy, wrote about the Rebecca Tuval brouhaha in his article A Line in the Sand for Academic Philosophy. If you are interested, I thought the whole article was worthwhile.

He summarized the Tuvel affair thus:

Rebecca Tuvel is an assistant professor at Rhodes College ... Her essay “In Defense of Transracialism” (Hypatia 32.2 [Spring 2017], pp. 263-78) is, to be fair, not consistently scintillating, creative, or convincing. However, few philosophy papers have any of those qualities, and almost none have all three. What the paper does do is lay out relatively clearly the motivation for a fairly intuitive argument. I’ll give my version of it here:
  1. We have compelling reasons to accept the identity claims of transgender individuals.
  2. Transracial identification is relevantly similar or analogous to transgender identification.
  3. The reasons commonly given for not accepting transracial identification are either not compelling or not relevant.
  4. From 1, 2, and 3, the balance of reasons compels us to accept the identity claims of transracial individuals.
  5. If the balance of reasons compels us to accept something, we should accept it.
  6. From 4 and 5, we should accept the identity claims of transracial individuals.
...

Other philosophers wrote and signed an open letter calling for the paper’s retraction. ...

The letter’s most important point is hidden in the first complaint: that Tuvel “uses vocabulary and frameworks not recognized, accepted, or adopted by the conventions of the relevant subfields.” In the Daily Nous comments, academics in these subfields struggled to identify precisely which arguments Tuvel failed to cite or address, or where her thinking might have gone wrong on a more than superficial level. Indeed, many philosophers of both gender and race have come out against retraction. But “the relevant subfields” are not really the academic studies of gender and race. They are the political interests and values associated with a certain conception of those topics. The real complaint is that anyone who publishes in a journal like Hypatia, itself a blatantly activist organ, ought to share those politics. In turn, the necessary politics are built in to the “vocabulary and frameworks” used by the academics. This is ideological alignment dressed up as intellectual expertise.

This is fairly well-known background for those who have been paying attention to this. What interests me more is his assessment of how the field of philosophy got to this point. He makes several points, but one of them is:

Another concerns the methodology of philosophical ethics. Much of ethics is quasi-scientific: it involves investigating our intuitions about particular cases and generalizing them into a broadly explanatory theory. However, different people have different intuitions. Norms about the nature of intuitive reasoning (e.g. “reflective equilibrium”) and about how much weight philosophers should give to other people’s intuitions have never quite taken hold, except in the “experimental philosophy” movement. In the modern academy, with its myriad specializations, it is easy to put together a “relevant subfield” of philosophical ethics not by linking together a set of situations, puzzles, or theories but by finding a group of people who share the same intuitions about cases. The actual difficult work of ethics is completely removed, because people with deep disagreements can, if they wish, simply read different journals, go to different conferences, and so on. I will leave a comparison to the state of American politics as an exercise for the reader.
That's exactly what I think has happened throughout the humanities, although it is not universal yet. It might provide us with part of an answer as well. Non-Progressive academics shouldn't just sequester themselves in little intellectual ghettos, but citation is life: making sure to include non-Progressive voices in the conversation could help. (If an academic publishes and no one cites the work, was the work really published?) Similarly, an academic community could form that replaces a certain subfield. At this point, I feel like that is actually a necessity. Race, ethnicity, and gender are far too important to leave to the loonies.

Traldi ends with a call to save the field from mob justice, from which I got the title for this post. I think the humanities are worth saving, but I'm not quite sure how it works out yet.

Well, something's up, anyway.

I wonder if there isn't a 'free exercise' claim here?

IRS Execs Think Their Lives are at Risk in TEA Party Case

That's interesting. What are you afraid to tell us, I wonder?
"This documentation, as the court will see, makes very personal references and contains graphic, profane and disturbing language that would lead to unnecessary intrusion and embarrassment if made public," their attorneys argued in a recent court brief. "Public dissemination of their deposition testimony would put their lives in serious jeopardy."
This sounds like the rare case in which intrusion and embarrassment are wholly appropriate.

Plato and Cognitive Bias

One of the ways in which we hide how similar our ancestors are to ourselves, Bertrand Russel noted, is by inventing technical terms for things we knew all along.
[T]he richest precedent for behavioural economics is in the works of ancient Greek philosophers. Almost 2,500 years before the current vogue for behavioural economics, Plato was identifying and seeking to understand the predictable irrationalities of the human mind. He did not verify them with the techniques of modern experimental psychology, but many of his insights are remarkably similar to the descriptions of the cognitive biases found by Kahneman and Tversky. Seminal papers in behavioural economics are highly cited everywhere from business and medical schools to the social sciences and the corporate world. But the earlier explorations of the same phenomenon by Greek philosophy are rarely appreciated. Noticing this continuity is both an interesting point of intellectual history and a potentially useful resource: Plato not only identified various specific weaknesses in human cognition, he also offered powerful proposals for how to overcome these biases and improve our reasoning and behaviour.

Many of Plato’s dialogues dramatise the habits and processes that lead humans to false conclusions. He depicts people believing what they want or what they are predisposed to believe (confirmation bias); asserting whatever comes most readily to mind (availability bias); reversing their opinions about identical propositions based on the language in which the propositions are presented (framing); refusing to relinquish current opinions simply because these happen to be the opinions they currently possess (a cognitive version of loss aversion); making false inferences based on the size and representativeness of a sample of a broader population (representativeness heuristic); and judging new information based on salient current information (a version of anchoring). And this is only a partial inventory of the mental errors that he catalogues and dramatises.
Plato was also very good at math, a point that many contemporary readers miss. The Greeks didn't have algebra, but they did have a highly-advanced approach to geometry that allowed them to solve many complex mathematical problems. Thus, while you might not expect Plato to provide a criticism of contemporary statistical mathematics (since he did not have access to such systems), in fact he's aware of a number of the problems such systems will encounter because he has thought a great deal about the real nature of mathematical objects like numbers and shapes.

It may be hard for contemporary thinkers who are schooled in our advanced forms of mathematics to think there is much to be gained by learning the ancient forms as well. Yet a new way of thinking about the same problems offers unexpected benefits. The philosophical investigation into the nature of mathematicals offers additional benefits. What we often learn is how difficult it is to be sure of what we think we know. Thus:
Intellectual humility and overconfidence can stem from purely cognitive processes, but they are also correctly understood as moral achievements or failings. Someone who always thinks that he is right about everything... is making a moral as well as a mental mistake. Similarly, the cultivation of intellectual humility is, in part, the cultivation of an ethical virtue.

Nussbaum's Jefferson Lecture

It's appropriately ancient, and as always with Nussbaum, I wonder how much more she knows about her goals than she makes clear to her audience. We must transform anger with honor, she says -- or, at least, that Athena did. She does not go on to conclude that we can, and yet it is the clear and correct conclusion from her argument.
As the drama begins, the Furies are described as repulsive and horrifying. They are said to be black, disgusting; their eyes drip a hideous liquid. Apollo even says they vomit up clots of blood that they have ingested from their prey. They belong, he says, in some barbarian tyranny where cruelty reigns.

Nor, when they awaken, do the Furies give the lie to these grim descriptions. As Clytemnestra’s ghost calls them, they do not speak, but simply make animal noises, moaning and whining. When they do begin to speak, their only words are “get him get him get him get him,” as close to a predator’s hunting cry as the genre allows....

Unchanged, these Furies could not be at the foundation of a legal system in a society committed to the rule of law. You don’t put wild dogs in a cage and come out with justice. But the Furies do not make the transition to democracy unchanged. Until quite late in the drama, they are still their bestial selves, threatening to disgorge their venom on the land. Then, however, Athena persuades them to alter themselves so as to join her enterprise. “Lull to repose the bitter force of your black wave of anger,” she tells them. But of course that means a virtual change of identity, so bound up are they with anger’s obsessive force. She offers them incentives to join the democracy: a place of honor, reverence from the citizens—but only if they adopt a new range of sentiments, substituting future-directed benevolence for retribution. Perhaps most fundamental of all, they must listen to the voice of persuasion.
Nussbaum says they are offered "places of honor," but also "reverence" -- and reverence is a form of honor too. In return, what must they do? They must "listen to the voice of persuasion" -- and that, too, is a kind of honoring. First, it is a kind of honor because it is a show of special respect to listen to the voice while being open to being persuaded. We don't take advice from just anyone, nor lay aside long-established habits. Athena is demanding honor from them, and offering them honor in return.

The effect is transformative, not just of the Furies but for Athens as well. Honor must be given to be received, and when one is brought into the community that gives and shows honor, peace becomes possible.

Yet then Nussbaum, later in her address, invokes honor in a negative way that seems to undermine her entire argument. I wonder why she does, aside from the clear intent to insult Donald Trump.
Elaborate codes of honor and status led, indeed, to constant status-anxiety and to many duels responding to purported insults. What’s wrong with the obsession with status is that life is not all about reputation, it is about more substantial things: love, justice, work, family. We all know people today who are obsessed with what other people think of them, who constantly scan the Internet to see who has been insulting them.
Indeed it is the biggest problem with Donald Trump that he does not know how to give honor, only how to demand it for himself. Yet reputation (another sort of honor: you have a good reputation if people say good things about you, which is a way of honoring you) enables the 'substantial things' she mentions. Consider work, as Louis L'amour often reminded his readers when he writes about why people might have killed over an insult like being called a "liar." Who will work with someone who is called a liar in the streets? In a poorer time when reputations tended to be well-known among smaller communities, such a name could mean the end of your ability to participate in work at all.

Who would bind their lives with such a person, as in love or the marriage that could bring out a family? The fight for what she calls status is not insubstantial, but rather, in earlier societies it played a crucial role in establishing the conditions for attaining the 'substantial things.'

Of course, some might love a man with a bad reputation -- or a woman, like the one John Wayne's character comes to love in Stagecoach. They might because they come to know the individual, and not just the reputation. But their election to trust the person in spite of his bad reputation -- that, too, is a kind of honor. And this honor, as honor does, transforms.

Mike Pence is the Devil, Mother's Day Edition

Now that the 'ctrl-left' is pretty sure it's got Trump on the ropes -- no doubt he'll be impeached any day, since all the newspapers say he should be -- it's time to move on to demonizing Mike Pence. We got round one out of his horrible refusal to dine with women besides his wife; well, at least, fifteen years ago he felt that way and nobody bothered to check if he still did.

Round two: he sometimes calls his wife "Mother."
One unlucky legislator stuck next to Pence tried to make conversation, but found even at dinner she couldn't shift Pence off his talking points. Gov. Pence shouted to his wife, Karen, his closest adviser, at the other end of the table.

"Mother, Mother, who prepared our meal this evening?"

The legislators looked at one another, speaking with their eyes: He just called his wife "Mother."

Maybe it was a joke, the legislator reasoned. But a few minutes later, Pence shouted again.

"Mother, Mother, whose china are we eating on?"

Mother Pence went on a long discourse about where the china was from. A little later, the legislators stumbled out, wondering what was weirder: Pence's inability to make conversation, or calling his wife "Mother" in the second decade of the 21st century.
There's other stuff in this profile: he's a Christian, but not the kind of Christian who thinks that progressive social programs are the ideal tool for religious expression; there are unsubstantiated accusations from people who used to know him, or who like what he did but don't like how he did it; he's way too religious for the author's taste.

If there are so many reasons to dislike Pence, why include this strange tidbit about how he refers to his wife in their own home? They make it sound weird, which to me suggests that the author is childless. Pence and his wife have three children. In a house full of kids, everyone but you is calling her "Mother," and if you want to communicate effectively with those children you'll adopt their usage when speaking with them. So too with her, who is likely to tell the children information they need to know about "Daddy" or "Father." In their own house, eating off their own china, it's not strange that they'd fall into what must have become a common mode of speaking in that particular context over decades of child-rearing.

But of course that's the point, isn't it? Child-rearing is weird now, at least among the readership of Rolling Stone. Being a Christian is weird. Taking your wedding vows seriously is weird. What could be stranger than seeing yourself and your spouse, inside your own house, as related to the context of that household you built in the role of mother and father?

These things used to be ordinary. They almost defined ordinary. Now they're proof of moral wickedness: a failure, I suppose, to evolve.

But don't these same people tell us that evolution is random and without purpose or meaning? Motherhood, so necessary for the process of evolution, is not lacking in these things.

Why Are We Doing This?

Early moves by insurers suggest that another round of price hikes and limited choices will greet insurance shoppers around the country when they start searching for next year's coverage on the public markets established by the Affordable Care Act.
Before Obamacare, I had a policy I kept from 2003 until, years after it became a grandfathered plan I couldn't change in any way, I lost it because the company quit selling it. I was never in a position of having to go out each year and "search for next year's coverage." Now I am in exactly that position.

Before Obamacare, that plan that I had changed only in that the premiums went up slightly from year to year. After Obamacare, the cost tripled before the policy was discontinued.

Before Obamacare, that plan had a network I didn't even have to worry about because any doctor you happened upon would certainly be on it. If you got drug to the hospital for some reason, you didn't have to first check to see if everyone in that hospital (including the anesthesiologist) was on the plan. They would be on the plan. Now, you have to agree to pay charges without having any idea if your network includes anyone at that hospital.

Nor can you check, actually, as the ACA's website doesn't have fully updated information for this year. You can find out if they took the plan last year, but every year, networks narrow and prices increase.

Why are we doing this?

Dolly Parton Lights the Way

I just passed through Gatlinburg, Tennessee. The damage from last year's fires is still highly evident in that town and the surrounding country, and will be for some time. By coincidence one of my cousins is a civil engineer up that way, and he has his hands absolutely full trying to rebuild the hundreds and hundreds of structures that were destroyed -- indeed, I think he said it was a few thousand structures he had on his plate. There is a real shortage of engineers who are experienced working on mountainsides, and thus there isn't the flood of help from outside the Tennessee mountains that one would expect.

So it is with pleasure that I read about native daughter Dolly Parton's extraordinary generosity in helping her fellow folks. Having grown up in tremendous poverty, and then attained substantial wealth, she never forgets how hard life can be in those mountains.

"The Ctrl-Left"

Via Anarchyball, an amusing term for the Antifa aspects of the left wing. It's meant as a parallel to the "alt-right," of course.

A Genuine Problem with the System

Reportedly, Attorney General Jeff Sessions is calling for his prosecutors to -- as a matter of course -- seek the harshest possible charges with the longest possible prison terms when prosecuting cases.

Well, actually, that's not quite what he said.
The policy memo says prosecutors should “charge and pursue the most serious, readily provable offense” — something more likely to trigger mandatory minimum sentences. Those rules limit a judge’s discretion and are typically dictated, for example, by the quantity of drugs involved in a crime. The memo concedes there will be cases in which “good judgment” will warrant a prosecutor to veer from that rule. But any exceptions will need to be approved by top supervisors, and the reasons must be documented, allowing the Justice Department to track the handling of such cases by its 94 U.S. attorney’s offices.
Mandatory minimums are a problem. Sessions, as a former lawmaker, bears some of the responsibility for that problem, but certainly not all of it. The heuristic that one should usually pursue the "most serious, readily provable" crime isn't even a bad standard: if a serious crime isn't readily provable don't pursue it, but if it is then of course it's your job to nail criminals for their serious crimes.

I would have left a lot more room for that "good judgment" exercise by lower-level officials, rather than requiring high-level officials to sign off on such uses of judgment. Still, it's not an unreasonable policy on its face.

What makes it a problem is, then, the mandatory minimums that exist in the law. That's a problem for legislators, not the Justice Department. I agree with the analysis that such minimums are not appropriate as a general principle. Nevertheless, it's not on the Justice Department to refuse to enforce the law when a crime is "readily provable" just because the law is badly written. It's on Congress to fix the law.

UPDATE:

My congressman, Doug Collins of Georgia's Mighty 9th, is working on trying to reform the laws in the way I'm discussing here. Specifically, he is focused on dealing with the mental health aspects of crimes. Collins is a former Air Force chaplain whose father was a state trooper.
"I've spent a lot of time with our sheriffs and going to our jails. One question I always ask is, 'How many in your jail would you classify as mental health or addiction issues?' The answer is that it ranges from about 35-40 percent of incarcerated individuals in some jails."...

"We're looking at the whole issue, at folks dealing with serious mental issues, but also from an economic perspective, the money perspective, making the best use of taxpayer dollars to not just incarcerate folks without getting them help," he added.
Mandatory minimums aren't the right answer to these issues. They might be to some issues -- I think I broadly approve of Project EXILE's moves to punish drug gangs who use guns with harsh penalties, as at least it pulls these kids off the street until they're too old to go around gunning each other down (as well as, being untrained thugs, often innocent people who were proximate to their targets). But there are many cases in which these mandatory minimums should be rethought by Congress.
