In this episode, hosts Dave Pietraszewski and David Pinsof are joined by guest Léo Fitouchi from the Institute for Advanced Study in Toulouse to explore the evolutionary psychology of self-control, puritanical morality, and retributive punishment. Fitouchi discusses why people frequently moralize harmless behaviors like overeating and hedonism, linking these judgments to folk psychological beliefs about cooperation and social costs. The conversation examines game-theoretic signals of trustworthiness, the distinction between shame and guilt, and how moral cognition computes proportional victim-focused punishment rather than pure deterrence. Finally, the speakers discuss criminal justice, hate crimes, elite status signaling, and Fitouchi's ongoing research into the moral psychology of authority.
QUESTIONS TO KEEP IN MIND
Hosts Dave Pietraszewski and David Pinsof introduce the podcast and guest Léo Fitouchi from the Institute for Advanced Study in Toulouse. They discuss the interdisciplinary nature of the institute, bringing together anthropologists, psychologists, and economists within an evolutionary framework.
So it's the Institute for Advanced Studies in Toulouse.

Guest Léo Fitouchi joins hosts Dave Pietraszewski and David Pinsof to discuss why people moralize harmless behaviors like overeating or hedonism. They explore the connection between self-control, delay of gratification, and reciprocal cooperation.
Cooperation is a delay of gratification problem because it requires resisting the immediate benefit of cheating.
“conditional cooperation or reciprocal cooperation or how however you want to call it is a delay of gratification problem” 7:54
Host Dave Pietraszewski and guest Léo Fitouchi discuss folk psychological beliefs regarding self-control, where indulging excessively in impulses like food or sex is thought to degrade one's character and future ability to honor pro-social obligations. They examine why certain impulsive behaviors are actively punished by social rules and institutions across various societies.
people believe that there should be a causal effect of your indulgence on your own capacity
“people believe that there should be a causal effect of your indulgence on your own capacity” 12:06
we're not merely avoiding and distrusting people who display a lack of self-control, we're actively punishing them
“not merely avoiding and distrusting people who display a lack of self-control, we're actively punishing them” 13:39
Léo Fitouchi contrasts his view on the cognitive logic of moral judgment with self-interest models, explaining with David Pinsof that moral rules emerge from principles of mutual benefit and collective action. They explore how moral cognition helps societies detect mutually beneficial social contracts and manage free rider problems in conditional cooperation.
moral cognition is an adaptation to detect what would be the social contracts
“moral cognition is an adaptation to detect what would be the social contracts” 23:46
Host David Pinsof, Dave Pietraszewski, and guest Léo Fitouchi discuss the game-theoretic foundations of morality, distinguishing simple coordination problems from prisoner's dilemma public goods games. They examine how self-control acts as a signal of cooperative potential, suggesting that resisting short-term temptations and delaying gratification signals trustworthiness and willingness to contribute to collective goods.
The more self-control I have, the the the better I am at resisting those short-term temptations, the more likely I am to cooperate with you in prisoners' dilemmas
“The more self-control I have, the the the better I am at resisting those short-term temptations, the more likely I am to cooperate with you in prisoners' dilemmas” 26:47
the fact that each of us refrains, even in private, of indulging in bodily pleasures, is itself a public good
“The final idea actually is that the fact that each of us refrains, even in private, of indulging in bodily pleasures, is itself a public good.” 27:31
The hosts and Léo Fitouchi explore the large cross-cultural variation in moralizing bodily pleasures and self-control. They discuss why certain societies are more puritanical than others, debating whether economic development, baseline impulsivity, or contextual threats shape the stringency of these moral norms across different populations.
societies in that are lower in self-control moralize low self-control more societies that are higher in self-control
“which is that societies in that are lower in self-control moralize low self-control more societies that are higher in self-control.” 32:41
Host Dave Pietraszewski and guest Léo Fitouchi discuss whether moralizing self-control stems from false psychological beliefs or broader cultural selection processes. Fitouchi explains that while some addictive behaviors impair self-control, people often hold false assumptions about how private indulgences correlate with cheating and general cooperation.
when I was thinking of the false psychological belief, I'm thinking of the false psychological beliefs about the effect of the behavior on your on your um on your traits.
“when I was thinking of the false psychological belief, I'm thinking of the false psychological beliefs about the effect of the behavior on your on your um on your traits.” 38:23
the theory just states uh when whenever people moralize uh harmless body pleasure is because they hold the folk psychological belief that this behavior has an indirect uh social cost
“the theory just states uh when whenever people moralize uh harmless body pleasure is because they hold the folk psychological belief that this behavior has an indirect uh social cost” 43:37
David Pinsof suggests that puritanical norms might act as self-fulfilling costly signals of reputation and commitment. While acknowledging the costly signaling perspective, Léo Fitouchi notes it does not fully explain why puritanical cultures are so specifically obsessed with bodily pleasure.
it might be that any norm that it that inflicts a cost on people becomes a reliable signal of moral character
“it might be that any norm that it that inflicts a cost on people becomes a reliable signal of moral character” 45:23
Dave Pietraszewski, David Pinsof, and guest Léo Fitouchi discuss self-conscious emotions, shame, and guilt. They examine how shame tracks reputational value and social exclusion, whereas guilt functions separately as a moral emotion tied to cooperation and repairing breaches in fairness or prisoner's dilemma situations.
Shame is triggered by cues of low social or reputational value, even when a person maintains the belief that they did nothing wrong.
“you can um not do something wrong but when you get cues that uh people want to” 51:33
Guilt and other moral emotions emerge in situations analogous to prisoner's dilemmas or public goods games rather than general coordination problems.
“So it's really guilt and other moral emotions come online when uh when we're in situations” 52:46
The hosts and Léo Fitouchi explore the evolutionary puzzle of punishment. While standard evolutionary theory suggests deterrence as the primary function of punishment, human moral psychology strongly emphasizes proportionality and just desserts, presenting a conflict between consequentialist and retributive accounts.
The retributivist cognitive design of punishment focusing on proportionality creates a puzzle for evolutionary psychologists because the form does not straightforwardly match standard deterrence rationales.
“So this is a puzzle for an evolutionary psychologist because the form doesn't seem to” 58:35
Léo Fitouchi discusses how moral psychology views cheating as creating a moral debt, where punishment functions analogously to material compensation. Rather than purely forward-looking deterrence, retributive punishment acts as a form of benefit extraction through cost infliction, bounded by the distributive computations of what offenders owe their victims.
for our moral psychology, punishment in the sense of an infliction of costs after uh uh cheating behavior is uh a form of compensation to the victim.
“punishment in the sense of an infliction of costs after uh uh cheating behavior is uh a form of compensation to the victim” 1:00:55
the quantity of costs that the offender deserves to receive in order for justice to be restored is just uh uh um uh a benefit extraction through cost infliction that is computed distributively.
“the quantity of cost that the offender deserves to receive in order for justice to be restored is just” 1:04:48
The speakers reframe punishment and deterrence around the victim rather than the perpetrator, explaining that retributive acts aim to restore the victim and satisfy their anger. Consequently, the perceived justice of punishment depends heavily on the victim's feelings and whether the victim personally benefits from deterring the offender.
the purpose of punishment um you know is not focused on hurting or or deterring the perpetrator so much as making things right for the victim.
“the purpose of punishment um you know is not focused on hurting or or deterring the perpetrator so much as making things right for the victim.” 1:09:14
Dave Pietraszewski, David Pinsof, and Léo Fitouchi discuss moral cognition, proportionality in punishment, and how the boundaries of moral contracts and outgroups shape our perceptions of just deserts and victim compensation.
Moral cognition is computing what is objectively the amount of benefits that the victim is allowed to take back in order for justice to be restored.
“Moral cognition is computing what is objectively uh the the amount of benefits that the victim is allowed to take back” 1:13:17
The speakers examine historical and structural differences between tort law and criminal law, arguing that criminal trials lacking victim compensation may foster greater punitiveness, while also exploring how group identity and shared vulnerability influence perceived just deserts.
Criminal law evolved historically from a system where kings profited from conflict fines rather than compensating victims.
“the king realized that uh the king could get money from uh the perpetrator by framing it as a conflict against the state versus a conflict against the victim.” 1:19:56
When a crime targets a group member, others in the group may perceive themselves as probabilistic victims, heightening the retributive response.
“In some sense, you are probabilistically the victim too.” 1:22:14
Host Dave Pietraszewski, host David Pinsof, and guest Léo Fitouchi discuss how crimes affecting entire groups or collective actions are punished more severely than individual torts. They explore how these societal violations relate to moral claims of shared harm and legal frameworks distinguishing between individual cheating and collective offences.
It explains why hate crimes are punished more severely than individual crimes.
“It explains why hate crimes are punished more severely than individual crimes.” 1:24:43
The speakers examine a hypothesis about elite art consumption as a costly signal of self-control and competence. Guest Léo Fitouchi and the hosts discuss whether preferences for highbrow culture signal trustworthiness or competence, and how socioeconomic class, future discounting, and perceptions of status intersect.
people are really making inference about competence, that is how smart people are, how sophisticated people are, but which also relates to self-control.
“people are really making inference about competence, that is how smart people are, how sophisticated people are, but which also relates to self-control.” 1:31:13
Hosts Dave Pietraszewski and David Pinsof discuss class dynamics, elite perspectives, and populism before interviewing guest Léo Fitouchi about his current work. Fitouchi explains his shift toward studying the moral psychology of authority and reciprocity rather than dominance.
the more the next idea I'm more interested about is like the moral psychology of authority
“the more the next idea I'm more interested about is like the moral psychology of authority” 1:39:10
The hosts and Léo Fitouchi debate whether human moral psychology is fundamentally net positive or negative, comparing moral intuitions to intuitive physics and discussing the evolutionary origins of moral disagreements.
there are moral disagreements because the cognitive algorithm is sensitive to input parameter.
“there are moral disagreements because the cognitive algorithm is sensitive to input parameter.” 1:42:32
just because something feels moralized to you, that's not data that it's actually a good thing per se.
“just because something feels moralized to you, that's not data that it's actually a good thing per se.” 1:44:20
In this closing segment of the podcast, hosts Dave Pietraszewski and David Pinsof casually discuss organic French fries, joking about receiving them through the mail. They humorously offer a guarantee to invite anyone onto the show who manages to successfully deliver homemade French fries to them, before concluding the episode and bidding listeners farewell until next week.
The hosts jokingly suggest that listeners mail them French fries.
“Send some French fries to us.” 1:48:32
The hosts guarantee an appearance on the podcast for anyone who brings them French fries.
“bring us french fries, we will have you on the podcast 100%.” 1:49:11
