| Abstract: | Often people believe to be “free” when deciding between different choice options. Ever since the pioneering work of Benjamin Libet, neuroimaging studies have repeatedly shown that it is possible to predict the outcome of subjectively free decisions from brain activity – even before people believe to be making up their mind. It has been debated whether this poses a challenge to the notion of free will. In this brief presentation I will discuss three points that have contaminated the debate on free will between neuroscientists and philosophers: (1) Do simple and seemingly random laboratory decisions really capture people’s intuitions about free choices? (2) What exactly does neuroimaging reveal about the link between prior brain activity and subsequent choices? Does it support a deterministic model of choice preparation? (3) Are there other neuroscientific challenges to free will, beyond the demonstration of choice- predictive brain signals? |
