The American legal system is based on a useful falsehood. It’s based on the falsehood that this is a nation of laws, not men; that in rendering decisions, disembodied, objective judges are able to put aside emotion and unruly passion and issue opinions on the basis of pure reason.

Most people know this is untrue. In reality, decisions are made by imperfect minds in ambiguous circumstances. It is incoherent to say that a judge should base an opinion on reason and not emotion because emotions are an inherent part of decision-making. Emotions are the processes we use to assign value to different possibilities. Emotions move us toward things and ideas that produce pleasure and away from things and ideas that produce pain.

People without emotions cannot make sensible decisions because they don’t know how much anything is worth. People without social emotions like empathy are not objective decision-makers. They are sociopaths who sometimes end up on death row.

Supreme Court justices, like all of us, are emotional intuitionists. They begin their decision-making processes with certain models in their heads. These are models of how the world works and should work, which have been idiosyncratically ingrained by genes, culture, education, parents and events. These models shape the way judges perceive the world.

As Dan Kahan of Yale Law School has pointed out, many disputes come about because two judges look at the same situation and they have different perceptions about what the most consequential facts are. One judge, with one set of internal models, may look at a case and perceive that the humiliation suffered by a 13-year-old girl during a strip search in a school or airport is the most consequential fact of the case. Another judge, with another set of internal models, may perceive that the security of the school or airport is the most consequential fact. People elevate and savor facts that conform to their pre-existing sensitivities.

The decision-making process gets even murkier once the judge has absorbed the disparate facts of a case. When noodling over some issue — whether it’s a legal case, an essay, a math problem or a marketing strategy — people go foraging about for a unifying solution. This is not a hyper-rational, orderly process of the sort a computer might undertake. It’s a meandering, largely unconscious process of trial and error.

The mind tries on different solutions to see if they fit. Ideas and insights bubble up from some hidden layer of intuitions and heuristics. Sometimes you feel yourself getting closer to a conclusion, and sometimes you feel yourself getting farther away. The emotions serve as guidance signals, like from a GPS, as you feel your way toward a solution.

Then — often while you’re in the shower or after a night’s sleep — the answer comes to you. You experience a fantastic rush of pleasure that feels like a million tiny magnets suddenly clicking into alignment.

Now your conclusion is articulate in your consciousness. You can edit it or reject it. You can go out and find precedents and principles to buttress it. But the way you get there was not a cool, rational process. It was complex, unconscious and emotional.

The crucial question in evaluating a potential Supreme Court justice, therefore, is not whether she relies on empathy or emotion, but how she does so. First, can she process multiple streams of emotion? Reason is weak and emotions are strong, but emotions can be balanced off each other. Sonia Sotomayor will be a good justice if she can empathize with the many types of people and actions involved in a case, but a bad justice if she can only empathize with one type, one ethnic group or one social class.

Second, does she have a love for the institutions of the law themselves? For some lawyers, the law is not only a bunch of statutes but a code of chivalry. The good judges seem to derive a profound emotional satisfaction from the faithful execution of time-tested precedents and traditions.

Third, is she aware of the murky, flawed and semiprimitive nature of her own decision-making, and has she accounted for her own uncertainty? If we were logical creatures in a logical world, judges could create sweeping abstractions and then rigorously apply them. But because we’re emotional creatures in an idiosyncratic world, it’s prudent to have judges who are cautious, incrementalist and minimalist. It’s prudent to have judges who decide cases narrowly, who emphasize the specific context of each case, who value gradual change, small steps and modest self-restraint.

Right-leaning thinkers from Edmund Burke to Friedrich Hayek understood that emotion is prone to overshadow reason. They understood that emotion can be a wise guide in some circumstances and a dangerous deceiver in others. It’s not whether judges rely on emotion and empathy, it’s how they educate their sentiments within the discipline of manners and morals, tradition and practice.
