 Research in experimental philosophy has explored many aspects of lay beliefs regarding free will. Experimental philosophers have designed improved scales for measuring belief in free will (Nadelhoffer et al. 2014; Deery et al. 2015), they have investigated the role of the desire to punish in attributing free will (Clark et al. 2014), and they have examined the impact of the belief in free will on moral behavior (Baumeister et al. 2009). But the most intensively studied issue concerns intuitions about whether free will is compatible with determinism.
