Sapolsky, Chapter 16: Biology, the Criminal Justice System, and (Oh, Why Not?) Free Will (580-613) (Part Two 598-613)

• But does anything useful actually come of this?

• Grounds for skepticism about using neuroscience in the courtroom: Stephen Morse. Neurolaw sceptic, ok with M’naugton, but thinks cases are rare. Reviews valid criticisms he makes: 1. Juries might overvalue neuroscience images, 2. Descriptive vs. Normative.

• Morse supports a strong distinction between causation and compulsion. Causation is not itself an excuse. But Sapolsky argues that this still involves walling off a “homunculus” and that’s not plausible.

• Acknowledges an apparent problem. Neuroscience typically can’t predict individual behavior very much. Fictional exchange with prosecutor. 600

• Explaining lots and Predicting Little

• But is the lack of predictive power a problem in the argument? S. works through some cases in which probability of prediction decreases, but no less likely that it could be a case of compulsion. 601

• 602: Important methodological point: There's no less biology in the leg fracture vs. the other disorders, but level of biological explanation is different. Leg fractures are less connected to culture. Behavior is multifactorial and heavily cultural. (Oh god, another Henrich digression. Free will has a history.) Example: how much does biology predict depression? Factors are diverse biological mechanisms, including cultural factors. (But, point is, someone can be disable by depression, just like the leg fracture.)

• Marvin Minsky, “Free will: internal forces I do not understand”. Sapolsky adds “yet”.

• Neat charts showing historic trend to connect social behavior and biology in research journals. 604-605.

• If you still believe in mitigated free will:

• Case of Dramer and Springer and the spiritual explanation for epilepsy. Biblical version with Jesus.
• Sapolsky imagines an Inquisitor (witch burner). Must be puzzled occasionally by fact pattern. Mom has epilepsy.
• Growth of knowledge argument 607-608. read list. Most likely option is that our kids will look at us as idiots about moral responsibility and culpability.

• 608: practical outcomes. Not about letting violent criminals free. On the biological view, punishment can’t be an end in itself (restoring balance). Retributive punishment is an end in itself.

• Brain imaging suggests culpability judgements activate the cool and cognitive dlPFC, but punishment judgements activate more emotional vmPFC. “A frothy limbic state”. Makes sense that punishment is costly. But we need to overcome our attachment to punishment. It is involved in a lot of unjustified suffering.

• Recaps the transition we've made with epilepsy 610.

• Car free will. A kind of reductio argument.

Henrich, Joseph, "Hell, Free Will, and Moral Universalism"

• This excerpt from The WEIRDEST People in the World comes in the context of a section on "universal moralizing gods" which characterize the major world religions (though Buddhism requires some discussion). H's theory is that this cultural innovation in religions allows societies to grow, solving the problems associated with living with so many strangers, something our evolved psychology did not really prepare us for.

• The three innovations of moralizing religions are:

• contingent afterlife: how you behave in this life determines your after life or next life
• free will: encouraged followers to believe they could comply with moral code by acts of choice and will.
• moral universalism: moral rules are the same for all people. (Note how this overcomes groupish morality.)

• The rest of the excerpt goes into evidence of the effects of each feature on social life. The research related to free will is at top of p. 148.

• What consequences, if any, does this research have for our thinking about the modern problems of free will and moral responsibility?

• 1. Cultural variants on ways of thinking about agency make (or made, in the past) real differences in social morality, whether or not they are metaphysically grounded. They work to the extent that people can actually think of themselves as having FW and thinking this way changes their behavior.
• 3. The philosopher's concern with the metaphysical problem of free will is hard to reconcile with the cultural utility of a belief in free will. If a belief in FW motivates better outcomes, why do we care about it's metaphysical grounding?
• 4. When you tell your future kids "You can do it if you try. Don't let other people control your decisions. What do you want to do with your life?" you may really be motivating them to take up a particular set of values to approach challenges. But notice this is only valuable motivationally. At some point, your parents stopped saying this so much. Instead, "you're doing fine..."

Traditional vs. Naturalist Approaches to Free Will

• The traditional philosopher's approach:

Whether we have free will or not depends upon our answers to two metaphysical questions:

• "Is determinism true?" and "Are we exceptions to it?"
• Libertarians believe that when we act freely, we are the "first cause" (like God, by the way) in a chain of actions. In other words, humans are exceptions to determinism.

• Big Implication of traditional view: At least part of us (the homunculus) is absolutely free. Biological stuff can override our freedom in case of force or compulsion.

• The "naturalist" approach (biologists, cultural evolutionists, and some philosophers):

• We are products of nature. As far as we know, we are caused to be how we are. But that doesn't mean we can't be responsible for our behavior, just that there are natural limits to human responsibility. These limits are found by understanding agency and paying attention to how cultures shape the idea of free will (Henrich).

• What we have, in normal circumstances is "agency." Agency is "an ability to act in the world and to make myself accountable to others." I do this by conforming my behavior to the idea of a "normally competent agent." Having human agency means that I am determined (by biology and training) to be accountable for values that help us get along together, to "evade" bad outcomes.

• Free will and MR as a cultural concept. Evidence from Henrich and others. Part of a cultural package that weakened kin bonds that might not have been seen as "choose-able". Promotes idea of choosing a creed or code of conduct apart from loyalty to kin.

• Naturalists want us to pay attention to how we actually talk about Free Will. This will help us understand the culturally shaped concept of FW and the way biology and environment pose real limits to our freedom.

• Ordinary language analysis -- We know what we mean by free will, whether it exists in libertarian form or not! Maybe it's a cultural artefact. Maybe we use mental modules related to Theory of Mind and governing "animate" objects.

• To warm up your intuitions that FW is a cultural concept, consider how adept we are in understanding these sentences: "ordinary language analysis"
• I may choose to take up painting as a hobby.
• I cannot choose to become a concert violinists at this point in my life.
• I can choose whether or not I get ready for class.
• I have no choice, I have to turn you in to the police.
• I can't choose not to love you, but I can't see you any more.
• I've decided I don't love you any more. (aww...)
• Parent to child: You can do anything you put your mind to.
• Parent to child: You need to try harder.
• Parent to (older) child: You're doing fine. Just keep that up.

• Big implication of naturalist view: Agency is about "degrees of freedom". We are not all equally free. Environments and our own biology and upbringing can constrain our freedom.

Small Group Discussion

• Does the traditional or naturalist view make more sense of your experience of free will? Is free will the ability to make absolutely uncaused choices or the ability (which we have by degrees) to hold ourselves accountable to our values and social expectations?

Cases:

• Kimberly Potter -
• Amber Guyger - the police officer, off duty, who mistook her neighbor, Botham Jean, for an intruder and killed him.
• A man has a heart attack / epileptic attack while driving and kills a pedestrian. (Consider variations.)
• A man is working two jobs to support a family, nods off at the wheel and kills a pedestrian.
• A man knows his car is close to a dangerous malfunction. When it occurs, he loses control and kills a pedestrian.
• The tragic case of the man who left his baby in a hot car.
