Abstract
Recent evidence from psychological science and genetics suggests that genetic influences underlie all behavior as well as the most worrisome social inequalities. This may be considered to call into question traditional conceptions of agency and agent responsibility. They could be thought to be undermined if gene-environment transactions were sufficiently potent in influencing behaviors. Here we identify the theoretical parameters that require investigation and the conceptual challenges to agent responsibility that arise from research in behavior genetics. We (i) introduce the empirical basis of the discussion, (ii) identify the particular questions that arise from considering the connection between behavior genetics and agent responsibility in the context of the legal system, (iii) bring into focus the general challenges to agent responsibility, and (iv) outline a potential resolution.

Notes
Additionally or alternatively, consequentialist considerations may give reason to assign blame, praise, punishment, or reward. With regard to punishment, such considerations are typically discussed under the header of deterrence. Here we focus on questions of agent responsibility that are distinct from issues in deterrence theory.
Bobzien (1998).
Feresin (2009). This sentence reduction was specified independently of a different sentence reduction that was made due to the defendant’s psychiatric illness.
Doudna and Sternberg (2017).
Scurich and Appelbaum (2017, p. 772) contended that the “introduction of genetic evidence of a predisposition to violent or impulsive behaviour is on the rise in criminal trials” but argued that “its use in the legal process is likely to diminish” because, “a panoply of data suggests that such evidence is ineffective at reducing judgements of culpability and punishment”. Morse (2011, p. 208) lamented that “[i]t is seldom explained why a genetically driven predisposition justifies a sentence reduction”. That said, he noted that “[t]he use of G x E for making decisions about criminal responsibility and sentencing will surely increase”.
But also see Scurich and Appelbaum (2017, 2016); Appelbaum et al. (2015); as well as Appelbaum and Scurich (2014, p. 96); and Denno (2013). For evidence of the continued relevance of behavior genetic information in the law see González-Tapia and Obsuth (2015); Kogel and Westgeest (2015); Farahany (2015); as well as McSwiggan et al. (2017).
See e.g. Nahmias, Morris, Nadelhoffer and Turner (2006), Knobe (2014); Nahmias et al. (2014) as well as Scurich and Appelbaum (2016, p. 155). Knobe (2014, section 2) reported the surprising yet well replicated result that study participants who are asked to pass judgement on agents who are stipulated to be fully casually determined tend to assign them full moral responsibility. However, as Nichols and Knobe (2007) have observed, this result seems to persist only in cases where subjects pass judgment on concrete agents and cases. The abstract question of whether persons are fully morally responsible in a causally determined universe elicits the opposite and incompatibilist response. Knobe (2014, section 2) reported that no conclusive explanation of the divergence between abstract and concrete judgements has been presented. The intuitive explanation that concrete cases elicit emotional responses which bias judgements, while abstract cases elicit no such responses has been observed to be insufficient to explain the discrepancy (Knobe 2014). Knobe (2014, note 2) hypothesized that people simply do not rely on deterministic understandings of human action if the case presented is sufficiently concrete. Standard non-deterministic interpretations of human decision-making is hypothesized to override descriptions of determinism in these cases. According to Murray and Nahmias (2014) the incompatibilist judgements of study participants (holding agents not to be morally responsible in a deterministic universe) can be explained by a mistaken interpretation of determinism. The inferred mistake lies in interpreting “determinism to imply that agents’ mental states are bypassed by the causal chains that lead to their behavior” (p. 434). Once study participants realize that no such bypassing occurs and that human decision-making remains operative and tied to mental states even in a deterministic universe “significantly higher scores for agents’ moral responsibility, free will, and blameworthiness in the abstract scenarios” result (p. 452). These differences in scholars’ interpretations of study participants’ attributions aside, acceptance of determinism does not necessarily lead them to reject agency and responsibility.
