Determined: A Science of Life without Free Will

by Robert M. Sapolsky

We can all agree on that; however, we’re heading into very different terrain, one that I suspect most readers will not agree with, which is deciding that we have no free will at all. Here would be some of the logical implications of that being the case: That there can be no such thing as blame, and that punishment as retribution is indefensible—sure, keep dangerous people from damaging others, but do so as straightforwardly and nonjudgmentally as keeping a car with faulty brakes off the road.

It’s the same with hunger. Here’s one study that should stop you in your tracks (and was first referred to in the last chapter). The researchers studied a group of judges overseeing more than a thousand parole board decisions. What best predicted whether a judge granted someone parole versus more jail time? How long it had been since they had eaten a meal. Appear before the judge soon after she’s had a meal, and there was a roughly 65 percent chance of parole; appear a few hours after a meal, and there was close to a 0 percent chance.[*],[28]

I don’t have the data to prove it, but I think I can predict above the chance level which of any given pair of students will be the one who picks up the pen. It’s more likely to be the student who skipped lunch and is hungry. It’s more likely to be the male, if it is a mixed-sex pair. It is especially more likely if it is a heterosexual male and the female is someone he wants to impress. It’s more likely to be the extrovert. It’s more likely to be the student who got way too little sleep last night and it’s now late afternoon. Or whose circulating androgen levels are higher than typical for them (independent of their sex). It’s more likely to be the student who, over the months of the class, has decided that I’m an irritating blowhard, just like their father. Marching further back, it’s more likely to be the one of the pair who is from a wealthy family, rather than on a full scholarship, who is the umpteenth generation of their family to attend a prestigious university, rather than the first member of their immigrant family to finish high school. It’s more likely if they’re not a firstborn son. It’s more likely if their immigrant parents chose to come to the U.S. for economic gain as opposed to having fled their native land as refugees from persecution, more likely if their ancestry is from an individualist culture rather than a collectivist one. It’s the first half of this book, providing an answer to their question, “There, I just decided to pick up this pen—are you tell...

And as a truly remarkable exception that proves the rule, there have been reports of congenitally deaf individuals with schizophrenia whose hallucinations are in American Sign Language (where some hallucinate a pair of disembodied hands signing to them, or being signed to by God).[*],[23]

Whether at graduation ceremonies you wear the cap and gown or bag the garbage. Whether the thing you are viewed as deserving is a long life of fulfillment or a long prison sentence. There is no justifiable “deserve.” The only possible moral conclusion is that you are no more entitled to have your needs and desires met than is any other human. That there is no human who is less worthy than you to have their well-being considered.[*] You may think otherwise, because you can’t conceive of the threads of causality beneath the surface that made you you, because you have the luxury of deciding that effort and self-discipline aren’t made of biology, because you have surrounded yourself with people who think the same. But this is where the science has taken us.
