"For several decades, some researchers have argued that neuroscience studies prove human actions are driven by external stimuli—that the brain is reactive and free will is an illusion. But a new analysis of these studies shows that many contained methodological inconsistencies and conflicting results.

"'Score one for skepticism of claims that neuroscience has proven—or disproven—any metaphysical position," says Veljko Dubljevic, co-author of the paper and an assistant professor of philosophy at NC State who specializes in research on the neuroscience of ethics and the ethics of neuroscience and technology.

"'The problem is that neuroscientists in training are being taught these studies provide definitive proof of the absence of free will, and instructors aren't being careful about looking at the evidence that supports the claims that are made," Dubljevic says. "Teaching uncritical thinking like this in science courses is both unscientific and socially dangerous."

"At issue are studies like those pioneered by Benjamin Libet in the 1980s, which assessed brain activity in study participants who were asked to perform a specific task. Libet found brain activity preceded a person's actions before the person decided to act. Later studies, using various techniques, claimed to have replicated this basic finding.

"But in the first-ever qualitative review of these studies, researchers are finding that the results are far from conclusive. The review analyzed 48 studies, ranging from Libet's landmark 1983 paper through 2014.

"'We found that interpretation of study results appears to have been driven by the metaphysical position the given author or authors subscribed to—not by a careful analysis of the results themselves," Dubljevic says. "Basically, those who opposed free will interpreted the results to support their position, and vice versa."

"The researchers also found significant variability across studies. For example, a subset of studies that actually looked at where activity was taking place in the brain, and whether it was related to will (or intent to complete a task), often found conflicting results.

"'Meanwhile, the journal articles that drew the most forceful conclusions often didn't even assess the neural activity in question - which means their conclusions were based on speculation," Dubljevic says. "It is crucial to critically examine whether the methods used actually support the claims being made."

"'Numerous studies suggest that fostering a belief in determinism influences behaviors like cheating," Dubljevic says. "Promoting an unsubstantiated belief on the metaphysical position of non-existence of free will may increase the likelihood that people won't feel responsible for their actions if they think their actions were predetermined."

"And this isn't a problem solely within the neuroscience community. Earlier work by Dubljevic and his collaborators found challenges in how this area of research has been covered by the press and consumed by the public.

"'To be clear, we're not taking a position on free will," Dubljevic says. "We're just saying neuroscience hasn't definitively proven anything one way or the other.'"

Comment: So free will may exist.
