In 2008, researchers from the University of Minnesota and the University of British Columbia conducted experiments highlighting the relationship between a belief in determinism and immoral behavior. They found students who were exposed to deterministic literature prior to taking a test were more likely to cheat on the test than students who were not exposed to literature advocating determinism. The researchers concluded those who deny free will are more inclined to believe their efforts to act morally are futile and are, therefore, less likely to do so.

In addition, a study conducted by researchers from Florida State University and the University of Kentucky found participants who were exposed to deterministic literature were more likely to act aggressively and less likely to be helpful toward others.” Even determinist Michael Gazzaniga conceded: “It seems that not only do we believe we control our actions, but it is good for everyone to believe it.”” The existence of free will is a common characteristic of our experience, and when we deny we have this sort of free agency, there are detrimental consequences.

Does moral behavior draw on a belief in free will? Two experiments examined whether inducing participants to believe that human behavior is predetermined would encourage cheating. In Experiment 1, participants read either text that encouraged a belief in determinism (i.e., that portrayed behavior as the consequence of environmental and genetic factors) or neutral text. Exposure to the deterministic message increased cheating on a task in which participants could passively allow a flawed computer program to reveal answers to mathematical problems that they had been instructed to solve themselves. Moreover, increased cheating behavior was mediated by decreased belief in free will. In Experiment 2, participants who read deterministic statements cheated by overpaying themselves for performance on a cognitive task; participants who read statements endorsing free will did not. These findings suggest that the debate over free will has societal, as well as scientific and theoretical, implications.

Laypersons’ belief in free will may foster a sense of thoughtful reflection and willingness to exert energy, thereby promoting helpfulness and reducing aggression, and so disbelief in free will may make behavior more reliant on selfish, automatic impulses and therefore less socially desirable. Three studies tested the hypothesis that disbelief in free will would be linked with decreased helping and increased aggression. In Experiment 1, induced disbelief in free will reduced willingness to help others. Experiment 2 showed that chronic disbelief in free will was associated with reduced helping behavior. In Experiment 3, participants induced disbelief in free will caused participants to act more aggressively than others. Although the findings do not speak to the existence of free will, the current results suggest that disbelief in free will reduces helping and increases aggression.

And that’s what neurobiology is telling us: Our brains are simply meat computers that, like real computers, are programmed by our genes and experiences to convert an array of inputs into a predetermined output. Recent experiments involving brain scans show that when a subject “decides” to push a button on the left or right side of a computer, the choice can be predicted by brain activity at least seven seconds before the subject is consciously aware of having made it. (These studies use crude imaging techniques based on blood flow, and I suspect that future understanding of the brain will allow us to predict many of our decisions far earlier than seven seconds in advance.) “Decisions” made like that aren’t conscious ones. And if our choices are unconscious, with some determined well before the moment we think we’ve made them, then we don’t have free will in any meaningful sense.

Let me summarize my views on what modern evolutionary biology tells us loud and clear — and these are basically Darwin’s views. There are no gods, no purposes, and no goal-directed forces of any kind. There is no life after death. When I die, I am absolutely certain that I am going to be dead. That’s the end of me. There is no ultimate foundation for ethics, no ultimate meaning in life, and no free will for humans, either.

As an atheist, I chose to cling to naturalism, in spite of the fact that I lived each day as though I was capable of using my mind to make moral choices based on more than my own opinion. In addition, I sought meaning and purpose beyond my own hedonistic preferences, as though meaning was to be discovered, rather than created. I called myself a naturalist while embracing three characteristics of reality that simply cannot be explained by naturalism. As a Christian, I’m now able to acknowledge the “grounding” for these features of reality. My philosophical worldview is consistent with my practical experience of the world.
