A review of Free Will and Consciousness

Andrew Field1 A review of Free Will and Consciousness by Gregg D. Caruso2 Introduction: Free-Will and Consciousness is an ambitious book which attempts to promote the case for free will scepticism by exploring the recent scientific findings in the behavioural, cognitive and neurosciences (BCN). It argues that these findings are contrary to our common sense belief in free-will, according to which we consciously decide to choose different courses of actions. Such findings threaten our common sense belief that our conscious intentions cause our voluntary actions as mistaken because ‘much of what we do takes place at an automatic and unaware level.’3 Caruso is another scholar to sign up to the increasing membership of free-will scepticism that includes distinguished proponents such as Derk Pereboom4and Neil Levy5. Within the free-will debate, Caruso refers to his position as ‘hard-enough determinism’6 in which the underlying neural and psychological processes that produce all our actions and choices are part of a ‘causally determinate system (or ‘near-determined system’)7. Unlike hard determinism though, this position leaves open the possibility that there is some indeterminism in the universe, most likely at the micro level, ‘but it maintains that any such indeterminism is screened out at levels sufficiently low not to matter to human behaviour.’8 Organisation: Caruso spends the first third of the book presenting the traditional philosophical debate over the freewill problem discussing the positions of libertarianism and compatibilism. In the initial chapter, ‘The Problem of Free Will: A Brief Introduction and Outline of Position’, Caruso briefly discusses the tension between moral responsibility and determinism, provides a brief outline of the different philosophical positions in the debate, as well as a short discussion of the debate on moral responsibility. In Chapter two, ‘Against Libertarianism’, Caruso focuses on the two most prominent libertarian theories of Agent-Causation (AC) and Event Indeterminism, weighing up the plausibility of each theory.

Event-Indeterminism, on the other hand, is a naturalised version of libertarianism that attempts to escape the sui generis kinds of causation invoked by AC and other types of libertarianism. Robert Kane10, the main proponent of such theory, argues that a free action is caused by the effort of an agent’s will when in moments of moral conflict an agent has two or more options of action available, - which creates chaotic conditions of amplified quantum indeterminacy at the relevant neurological level -, are activated in the neural network. Caruso argues, however, that event-indeterminism cannot answer the Intelligibility Question: how is libertarianism intelligible in a scientific worldview that embraces the physical universe as causally closed? Kane is unable to give a plausible answer to how, given such quantum indeterminacy at the neural networks, that the agent is in control of choosing his actions, since he is unable to invoke a sui generis causation to account for his choosing of one action over the other. Moreover, a satisfactory answer cannot rest on the view that random quantum indeterminacy chooses the suitable course of action, since the agent does not have the required control for moral responsibility as we are not in control of quantum indeterminacy at the neural network level. In Chapter three, ‘Against Compatibilism’, at the start of this chapter Caruso gives us a general survey between the debate between compatibilism and incompatibilism by discussing how compatibilism’s response to the consequence argument is generally unsatisfactory, at least from an incompatibilist point of view. However, Caruso’s main argument – in this chapter - attempts to show that experimental evidence from social psychology research shows that compatibilism does not accurately reflect our pre-theoretical beliefs; rather they are libertarian and incompatibilist in nature. To paraphrase one experiment from Nichols and Knobe11, the vast majority of subjects (over ninety percent) answered that our universe was similar to the indeterminist universe presented in the experiment (rather than deterministic). Moreover, if our universe were deterministic then the vast majority of students responded that we would not be fully morally responsible for our actions. This means that proponents of compatibilism cannot assert that their conception of free-will is a reflection of our ordinary conception of it, and neither can they appeal to pretheoretical intuitions as support to their position. This conclusion becomes relevant when Caruso demonstrates an innovative internal argument against compatibilism in chapter four. In the rest of the book, Caruso begins exploring the relationship between free-will and consciousness. Throughout Free-Will and Consciousness Caruso simultaneously takes on libertarianism and compatibilism on closely related but separate fronts. Against libertarianism, Caruso wants to dispose its main virtue of the supposed phenomenology of conscious agency and free-will by offering us a deterministic account of the illusion of free-will by appealing to David Rosenthal’s version of Higher Order Thought (HOT) theory of consciousness12. Against compatibilism, Caruso argues that this 9 P.19 10 Robert Kane, A Contemporary Introduction to Free Will.

(Oxford: Oxford University Press 2005) deterministic feeling of free-will is largely not under conscious executive control, but is run by the adaptive unconscious and behaviour is automatically triggered nonconsciously by environmental determinants. Any folk-psychological account of free-will that compatibilism should endorse without appearing ad hoc should, as a necessary condition, have consciousness playing a leading role in initiating and causing behaviour. The recent findings from the BCN show this is not the case. Chapter four, ‘Free-Will and Consciousness (I) Automaticity and the Adaptive Unconscious’, explores the compelling empirical research on the adaptive unconscious and the automaticity of higher processes. Caruso sketches the adaptive unconscious as an evolutionary adaption which, as recent experiments in the last twenty years have shown, regulates higher-level processes to the unconscious, just as the unconscious is widely known to regulate sub-mental processes. In regards to automaticity, Caruso demonstrates countless examples where the environment unconsciously and automatically triggers a stereotype, which in turn causes us to act in unintended ways without conscious control, deliberation, guidance or will. However, this review will only concentrate on the question of whether the environment can trigger goal-directed behaviour nonconsciously without conscious control. Following Bargh’s auto-motive goal-directed model13 that was developed in response to this very question, it was found that “goal structures can be activated directly by relevant environmental stimuli … goals, once activated, produce the same outcomes whether they are put in motion by consciously made choice or through external stimuli.” The upshot of this model means that subjects will behave in a goal-directed manner that was selected without conscious control or guidance in that particular moment, although this goal-directed behaviour would have once been consciously chosen before it was nonconsciously implemented. This was demonstrated in an experiment where subjects were primed to behave in a co-operative manner in a fishing game where they could choose between behaving in a competitive manner by maximising profits by keeping all the fishes they took from the lake or by behaving in a co-operative manner by replenishing the lake by letting the fish go back into the lake. Importantly, in these experiments the participants were both unaware that these goals had been activated and also that they were behaving in a manner to achieve this co-operative goal. These experiments show us ‘we fail to realize just how wide open our unconscious minds are, and how easily our decision making is influenced by unnoticed environmental determinants.’14 Caruso says that ‘such results are disturbing precisely because they undermine our intuitive sense of conscious control’15 and compatibilism is threatened by this because the picture of the adaptive unconscious controlling the bulk of our day-to-day lives ‘is more threatening than normal determinist arguments because it suggests we do not possess the kind of conscious executive control we typically assume’16 Caruso is right to think that such experimental data pose a threat to the compatibilist sense of free-will by undermining the folk-psychological notion of executive conscious control being the commander of our moment to moment actions, but in no sense is this disastrous to their outlook. The compatibilist most John Bargh, “Auto-motives: Preconscious determinants of social interaction” in Tory Higgins and Richard M. Sorrentino (eds) Handbook of motivation and cognition, (New York: Guildford Press 1990) 93-140. 13 14 P.120 15 P.128 16 Ibid. likely will have to make concessions in regards to this by admitting that free-will is not the director of all decisions regarding our higher level mental processes, no matter how minor, since the experimental evidence shows that the phenomenology of such a belief was misguided. This is not an ideal backward step for them to make, but compatibilists might argue that real free-will consists in those moments when consciousness control, self-control, deliberation and planning are causally efficacious in making real-life decisions. Although Caruso argues there is not enough conscious control for us to be morally responsible for our actions in the basic desert sense, Caruso himself does suggest that consciousness ‘plays an important role in formulating long-term actions, plans and intentions’ although it does not initiate these actions or cause these actions, consciousness also plays a role in ‘non-spontaneous decision making by providing focal-attention to help prioritize and recruit subgoals and functions’17 It is a testament to Caruso’s internal argument against compatibilism that by invoking the threatening implications of the adaptive unconscious and the automaticity of behaviour to the severely reduced efficacy of conscious control to our numerous daily decisions that a fierce battleground between compatibilism and incompatibilism will be fought in this arena: how much conscious control do we have over our non-urgent moment to moment decisions? Does consciousness have a downstream effect on these actions, behaviours and decisions? Is this enough conscious control for free-will and/ or moral responsibility? In chapter five, ‘Free Will and Consciousness (II) Transparency, Infallibility and Higher-Order Thought (HOT) Theory’, Caruso argues that one of our defining features of consciousness, the apparent transparency and infallibility of consciousness is a cognitive illusion that leads us wrongly to infer that we are free and causally undetermined because we are unable to introspect the deterministic processes of our decision making. To explain such a deterministic process and cognitive illusion, Caruso endorses Rosenthal’s HOT version of the theory of consciousness. According to HOT theory, ‘a mental state is conscious only if one is, in some suitable way, conscious of that state.’18 By the transparency of consciousness, Caruso means that, we are conscious of everything in our minds. He argues convincingly that there is ample evidence to suggest that consciousness is not transparent, and this was covered in the bulk of chapter four, that many of our mental states, desires, intentions, judgements, beliefs and goals can often occur unconsciously. By the infallibility of consciousness, Caruso means that we are certain about the knowledge of our mental states and our judgments cannot be in error. He argues that the ability to know our own mental states is limited, as consciousness, even via introspection, does not always accurately represent our mental states to us. This leads us to confabulate reasons for acting, as our conscious phenomenology for acting does not match up with our actual reasons for acting, as illustrated in an example with hypnotized subjects, ‘[a]fter being hypnotized, subjects can enact a posthypnotic suggestion –e.g., “when you awake you will be immediately crawl around on your hands and knees.” When asked what they are doing, subjects almost immediately generate a rationale – “I think I lost an earring down here192021. Moreover, it is intimated that confabulation of our reasons for acting happens on 17 P.201 18 P.156 19 Michael Gazzaniga, The Social Brain. (New York: Free Press 1985) 20 Ernest Hilgard, Hypnotic susceptibility. (New York: Harcourt, Brace & World 1965) 21 George Estabrooks, Hypnotism. (New York: E.P. Dutton 1943) a daily basis) by arguing that we confabulate stories and create explanations as our conscious selves do not fully know why we act in the way that we do22 23 24 Assuming that daily confabulation of reasons is true (although some philosophers doubt it) it poses some deep and worrying problems for free-will when paired together with the situationist experiments. Reexamining the structure of confabulation, as the hypnotist example plainly illustrates, the supposed phenomenology of the subject’s reasons for acting does not match up with the actual mechanism of the reason for acting. Given the situationist experiments, the primary conclusion is that objects (banal everyday objects like a Lucozade bottle, a briefcase etc.) in our environment can nonconsciously select and influence our desires, motivations and goal-directed behaviour. The fundamental worry then is that we can never be sure, despite our supposed infallible phenomenology, when we are actually acting for our supposed reasons since nearly any object in the environment could be nonconsciously selecting our goaldirected behaviour without our awareness. The worry is not that we are always confabulating reasons, but rather we are unsure when we are confabulating reasons and when we are not, as our phenomenology for why we acted would still seem just as infallible, and we would be woefully ignorant that environmental determinants have influenced our decision making processes. In Chapter six, ‘Consciousness and Free Will (III): Intentional States’, Caruso focuses on two other phenomenological features of consciousness. Firstly, our intentional states are causally undetermined and arise spontaneously. Secondly, our feeling of conscious will: the feeling that we consciously initiate our behaviour through our conscious intentions and desires. To start with the former, Caruso believes that the feeling that our intentional states are casually undetermined is crucial to our illusory belief that we have free-will, as we are not conscious that our intentions and desires are themselves causally determined. This gives us a sense of freedom with our actions that our actions are free. This can be explained by HOT theory. According to HOT, the HOT’s are unable to represent the original causes of our desires and intentions so we are unable to remain aware of the causes of our desires and intentions. In regards to the latter, Caruso discusses the infamous Libet experiments that he believes successfully undermine a major part of the folk psychology of free-will, that our conscious intentions and willing’s cause our actions. For the sake of brevity, I will not explain the Libet experiment here, but the conclusions of his and similar experiments is that for simple motor actions, such as tapping your fingers on the desk, it appears that we have an unconscious intention to tap our fingers (called a readiness potential RP) before we have the conscious intention to tap our fingers. The Libet experiment, Caruso argues, suggest that conscious will is an illusion – it is not the case that we consciously initiate actions through our conscious intentions or decisions, rather our intentions and actions are initiated unconsciously. In Chapter seven, ‘Consciousness and Free-Will (IV): Self-Consciousness and Our Sense of Agency’, Caruso argues that the illusion of free-will is maintained by our sense of agency that includes the two 22 Timothy Wilson, Strangers to ourselves: Discovering the adaptive unconscious. (Cambridge, MA: Belknap Press of Harvard University Press 2000) Richard Nisbett and Timothy Wilson, “Telling more than we can know: Verbal reports on mental processes” 1977, 84 Psychological Review: 231 23 24 Michael Gazzaniga and Joseph LeDoux, The integrated mind. (New York: Plenum 1978) subjective components of ownership (characterized as I am experiencing the movement or thought) and of authorship (characterized as I initiate an action through my will). To account for this sense of agency, philosophers, theologians and laypeople have postulated the existence of a unified Self to account for this wilful behaviour, this is Caruso’s target in this chapter. The subjective experience of ownership can be explained away by the way in which HOT’s represent their target mental states by employing the indexical concept “I”, which not only makes one conscious of the target state, but also a sense of self to which the target state is represented as having by the HOT. However, in medical diseases like alien hand syndrome or schizophrenia (especially in the case of thought insertion), Caruso argues, the sense of ownership over our actions breaks down due to a self-identification error over our thoughts and actions which we do not ascribe to our unified self or sense of agency. To account for a sense of unity of our conscious, as well as HOT’s employing the essential indexical in representing its target state, in introspective consciousness (when I have a third-order thought of the HOT – which makes the HOT itself conscious) we identify that all of one’s conscious states belong to a single unified conscious subject, and we identify on a range of considerations from ‘personal history, bodily features, and psychological characteristics to current location and situation ‘.25 Accounting for a sense of agency, Caruso moves on to answering the question: what accounts for the experience of wilfully initiating action, being the author of my own actions, having the self-as-cause? He argues that ‘the relevant intentions and thoughts that precede an action are tagged with a sense of self (i.e. if they are experienced as owned by a seemingly unified self), and (a) the subsequent action is perceived as consistent with those thoughts, and (b) there are no other competing causes available for the action … on this account, one experiences a sense of self-generation or authorship when they draw causal inferences relating prior self-ascribed thoughts with consistent and self-ascribed actions.’26 An extended argument based on Caruso’s adaptive unconscious Let us return to chapter four, Caruso discusses an experiment that reveals the utility of the adaptive unconscious. The IOWA Gambling Task is an experiment that is designed to test real-life decision making performance27. The subject sits in front of four card decks labelled A, B, C and D, is given $2000 facsimile money and told to earn as much money as possible and to lose as little as possible. The turning of the decks A and B will yield a larger reward than decks C and D (say $100 to $50 respectively), but the losses in decks C and D are much smaller and less regular than A and B. Over a sustained period of time, picking only the A and B decks will give you losses in the long run, but continually choosing decks C and D will give slow and steady monetary gain. Typically, the experiment lasts for a hundred turnings of the cards, but the subject will be unaware how long it will last for, and will be told to continue with the experiment until it is time to stop. Bechara et al. found that participants began to choose advantageously before they consciously realized which strategy worked best. He found that after about ten cards participants began to generate anticipatory skin conductance responses (e.g., their palms began to sweat) whenever they pondered a 25 P.229 26 P.243 Antoine Bechara et al, “Deciding advantageously before knowing the advantageous strategy”. (1997) 275 Science, 1293 27 choice that turned out to be risky, before they knew explicitly it was a risky choice. At about the same time (around ten cards) they began to avoid decks with large losses. It wasn’t until much later, at about eighty cards, that they were able to explain why decks C and D were better in the long run. And it wasn’t until about fifty cards – forty cards after the gamblers started generating stress responses to the risky decks – that they were able to say they had a “hunch” that something was wrong with those decks. Bechara et al. concluded: ‘The results suggest that, in normal individuals, nonconscious biases guide behaviour before conscious knowledge does’ Caruso uses this example from cognitive neuroscience to demonstrate that our adaptive unconscious undermines the following assumption: ‘Most of us assume that our decisions and actions are guided by conscious executive control. We assume that we are consciously and systematically processing incoming information in order to construe and interpret our world and to plan and engage in courses of action.’ 28 Caruso demonstrates an admirable point about how our adaptive unconscious undermines the executive conscious control we have regarding day-to-day events. However, the notion of adaptive unconscious can be pushed further to demonstrate how important it is as a potentially crucial factor in an agent’s decision making process that may affect his life in significant ways. Before continuing, I will briefly describe the patients suffering from ventromedial prefrontal lobe damage, to whom the healthy controls were compared to as a paradigm for abnormal decision making processes. Bechara et al29 noticed that individuals who suffered specifically from ventromedial prefrontal lobe damage as compared to general brain damage had abnormal decision making tendencies. It was often the case that patient E.V.R, a prototypical example of this condition, ‘often decides against his best interest, and is unable to learn from his mistakes. His decisions repeatedly lead to negative consequences.’ In the IOWA gambling task, similar to the controls, patients with ventromedial prefrontal lobe damage began by sampling both the good (C-D) and bad (A-B) decks, but instead of remaining the majority of the time like the controls with the advantageous decks, these patients returned frequently to the disadvantageous decks. Now, I will explore whether there is a link between abnormal decision making tendencies and what we would typically describe as a paradigm example of a life that is the outcome of bad decision making consequences, such as being in jail. Recent research has tested the differences between healthy controls and criminals (who are physically and psychologically healthy) on the IOWA gambling task. A paper from Yechiam30 that tested this hypothesis states that our results ‘provide support for the similarity hypothesis31 in that criminals, in general, made poor decisions characterized by failure to learn from repeated mistakes … Although both prisoners and healthy controls preferred the disadvantageous decks initially, only the control group eventually learned 28 P.113 Antoine Bechara et al, “Insensitivity to future consequences following damage to human prefrontal cortex,” (1994) 50 Cognition, 7 29 Eldad Yechiam et al. “Neurocognitive deficits related to poor decision-making in people behind bars.” (2008) 15(1) Psychonomic Bulletin & Review: 44 30 31 Michael Gottfredson and Travis Hirschi, General Theory of Crime. (Stanford, CA: Stanford University Press 1990) to strongly prefer the advantageous decks. None of the prisoner groups learned to prefer the advantageous decks by the end of the task.’32 This conclusion sounds remarkably similar to the patients that suffered from ventromedial prefrontal cortex (vmPFC) damage. Could it be the case that criminals suffer from a decision making abnormality analogous to those with vmPFC damage without the physical damage? Potentially so when we consider that long-term cocaine abuse also damages decision making in the vmPFC33. The results from Yechiam et al34 continue ‘drug and sex offenders, and to some extent, OWI [dangerous driving] and theft criminals as well, behaved similarly to chronic cocaine abusers [on the IOWA gambling test]. Compared to controls, these groups weighted gains more than losses … Cocaine abuse has been linked to a reduction in the level of the neurotransmitter dopamine, which has a central role in reward learning. Using cocaine results in an increase in exhilaration to immediate gains35 It is therefore not surprising that forms of crimes characterized by addiction (e.g. drug and sex crimes) are associated with a similar tendency to prefer alternatives that produce high gains and discount their potential losses36.’ Based on the previous discussion, what does it mean that all the criminals that participated in this experiment did not choose the advantageous decks over the disadvantageous decks? And, in this context, what is the relationship between the adaptive unconscious and the criminal in the sample represented? 37 Before investigating these questions, it is worth noting some preliminary caveats about the IOWA gambling task. Firstly, as mentioned earlier in the text, each participant understands that the objective of the game is to maximise as much profit as possible. Thus, we shall assume, that barring any psychological illnesses, participants would know that by choosing the advantageous decks over the disadvantageous decks they were acting in their own best interests. Secondly, the rules of the game are fully explained to each participant, and their understanding of the rules and objectives of the game are tested for satisfactory 32 Emphasis mine 33 A Verdejo-Garcia et al, Emotion, decision-making and substance dependence: a somatic-marker model of addiction. (2006) 4 Current Neuropharmacology: 17 Eldad Yechiam et al. “Neurocognitive deficits related to poor decision-making in people behind bars.” (2008) 15(1) Psychonomic Bulletin & Review: 44 34 35 A McGregor and D Roberts, Dopaminergic antagonism within the nucleus accumbens or the amygdala produces differential effects on intravenous cocaine self-administration under fixed and progressive ratio schedules of reinforcement. (1993) 624 Brain Research: 245 36 Though it needs further investigation as to whether one of the potential determining factors for the behaviour of criminals is due to reduction in dopamine, these conclusions show that when it comes to decision making supposedly mentally healthy individuals criminals display similar cognitive decision making errors of chronic cocaine addicts. This disturbing implication raises some serious questions, such as the following, which will not be followed up here, if we class individuals suffering from long-term cocaine addiction with diminished responsibility (in the non-hard determinist metaphysics utilised by the court of law) should particular sub-set of supposedly healthy criminals with decision making abnormalities have diminished responsibility for their actions as well? 37 It should be stressed that this discussion is focused on the criminals that participated in the IOWA gambling task within this paper. This article does not assume the following statements: (a) that all individuals who lack the adaptive unconscious are motivated to become criminals; (b) that you cannot commit criminal behaviour without lacking the adaptive unconscious mechanism; (c) that a criminal cannot successfully pass the IOWA gambling task; (d) committing a crime is directly due to not understanding your best interests comprehension before the task can begin. This ensures that failing at the task cannot be due to a lack of information. So, what is the best explanation that all the criminals who participated in the experiment preferred the disadvantaged decks? Two brief reasonable explanations can be considered. Firstly, the criminals did have the nonconscious mechanisms similar to the healthy controls to stay away from the “bad decks” but they preferred these decks over the “good decks” anyways due to the high immediate gains of this deck. However, this explanation appears unsatisfying if we assume that individuals typically act what appears to them to be in their own self-interests, as repeatedly choosing the “bad decks” would contradict this notion (since it is against the objective of the task). This leads us to the second explanation which is much stronger: the criminals did not receive the nonconscious mechanism that the disadvantageous “bad decks” were A and B like the healthy controls did; (b) these criminals, for unknown decision making reasons, do not know which decks are in their best interests, so they systemically prefer the decks which give them immediate gains and highs, like longterm cocaine abusers. Similar to long-term cocaine abusers that suffer from reduced dopamine levels, these criminals do not learn from their repeated mistakes of choosing this “bad deck” and since they are more focused on the immediate gains they do not worry about the long-term losses. So, unlike healthy controls who eventually realise the advantageous decks compared to criminals, this appears to highlight that it is not in the conscious executive control for the criminal to realise that he should be preferring the “good decks” C and D rather than the “bad decks” A and B. To briefly recap the argument so far, the IOWA gambling task is a decision making tool that simulates real life decision making. In a recent experiment that utilised the task, all the criminals that participated in the task failed to prefer the advantageous decks, whilst the majority of the healthy controls learned to do so. Cognitive neuroscience experiments have demonstrated that these healthy controls have a nonconscious mechanism (the adaptive unconscious) which produces physiological symptoms in the healthy control at the start of the experiment when they are initially preferring the bad decks which consists of cards which have immediate gains and large losses. These physiological symptoms, such as sweaty palms, were unconscious indications that influenced the healthy controls to realise that preferring these bad decks were a risky choice which should eventually be avoided. The best explanation which accounts to why all the criminals failed the task was due to their lack of having the non-conscious mechanism. It appears not to be in the conscious executive control of the criminal that he should prefer the “good decks.” If it were the case that consciously criminals may figure out which were the “good decks” and which were the “bad decks” then you would expect to find a few criminals act in a similar manner to the healthy controls on the test, even if it took them longer to come to this realisation. However, this is not the case, as all the criminals that participated systematically and frequently preferred the “bad decks” in a similar manner to patients suffering from vmPFC damage and long-term cocaine abuse. This suggests that these criminals all had abnormal decision making processes, despite any physical manifestations of brain damage, which meant that they would act against their best (not self) interest, repeatedly failing to learn from their mistakes, and make decisions that would lead to negative consequences. This all stemmed from factors which were out of their control beginning with the adaptive unconscious failing to reveal the best interests (in this context, the “best decks”) to the criminal, as a consequence of this his consciousness could never reveal to him his best interests, which entailed it was never in the conscious executive control of the criminal to initiate action and behaviour in his best interests. The criminals whom participated in the experiment had deficiencies in their adaptive unconsciousness that led to abnormal decision making tendencies that were not prevalent in the majority of the healthy controls. These decision making tendencies in some sense had to lead to circumstances that led to the criminals being in jail.38 Conclusion In conclusion, Free Will and Consciousness is highly recommended as it convincingly sets out to achieve what it desires: provide a compelling determinist account of consciousness that accounts for the libertarian phenomenology of free will, whilst at the same time its comprehensive account of consciousness provides a threatening innovative internal challenge to compatibilism. Lastly, the vast amount of neuroscience research conducted in this monograph is staggering, including insights ranging from Jeannerod on motor control to Frith’s neurocognitive model in schizophrenia. No stone is left untouched in the domain of scientific research. 38 Whether this deficiency in the adaptive unconscious directly motivated the criminal act is irrelevant. What matters is that the criminal that participated in the experiment had an abnormal decision making process (suggested by failing the IOWA gambling task), due to a deficiency in the adaptive unconscious. These decisions eventually caused the individual to go to jail for committing a criminal act. References John Bargh, Auto-motives: Preconscious determinants of social interaction in Tory Higgins and Richard M.
