Paul J. Zak (born 9 February 1962) is an American neuroeconomist.
Zak graduated with degrees in mathematics and economics from San Diego State University before acquiring a PhD in Economics from the University of Pennsylvania. He is professor at Claremont Graduate University in Southern California. He has studied brain imaging, and was among the first to identify the role of oxytocin in mediating trusting behaviors between unacquainted humans. [1] Zak directs the Center for Neuroeconomics Studies [2] at Claremont Graduate University and is a member of the Neurology Department at Loma Linda University Medical Center. He edited Moral Markets: The Critical Role of Values in the Economy (Princeton University Press, 2008). [3] His book, The Moral Molecule was published in 2012 by Dutton. The book summarizes his findings on oxytocin and discusses the role of oxytocin in human experiences and behaviors such as empathy, altruism, and morality.
Zak's research aims to challenge the thought that people generally are driven primarily to act for what they consider their self-interest, [4] and asks how morality may modulate one's interpretation of what constitutes "self-interest" in one's own personal terms. [5] Methodological questions have arisen in regards to Zak's work, however. [6] Other commentators though have called his work "one of the most revealing experiments in the history of economics." [7] According to The Moral Molecule, Zak's father was an engineer and he takes an engineering approach to neuroscience, seeking to create predictive models of behavior.
His research and ideas have garnered some criticism, particularly from science writer Ed Yong, who points out that oxytocin administration boosts schadenfreude and envy. [8] Oxytocin administration increases the salience of social cues, suggesting that priming effects in these experiments explain their findings. [9] For example, Zak has shown that endogenous oxytocin release eliminates in-group bias indicating that the critiqued effects are due to supraphysiologic doses of oxytocin coupled with antisocial priming. [10]
Neuroscientist Molly Crockett also disputes Zak's claims, referring to studies that show oxytocin increases gloating, bias at the expense of other groups, and in some cases decreasing cooperation; suggesting oxytocin is as much an "immoral molecule" as 'the moral molecule' Paul Zak claims. [11]
Zak has coined the term "neuromanagement" to describe how findings in neuroscience can be used to create organizational cultures that are highly engaging for employees and produce high performance for organizations. [12] He has developed a methodology called Ofactor that quantifies organizational culture and identifies how to continuously improve culture to increase trust, joy, and performance. He has used Ofactor to help organizations ranging from nonprofits to startups to Fortune 50 companies change their cultures. His Ofactor research reflects the approach advocated by his late colleague at Claremont Graduate University, management guru Peter F. Drucker, in which organizations with flat hierarchies empower employees. His 2017 book Trust Factor: The Science of Creating High-Performance Companies shows leaders of organizations how to create and sustain a culture of trust.
Zak has published more than 200 peer-reviewed papers, book chapters, and commentaries. He was listed by researchers at Stanford University as being in the world's top 0.3% of the most cited scientists. [13]
Zak's lab has discovered neurologic signals that reflect engagement in stories and predict post-narrative behaviors. [14] Some of this work was funded by DARPA to help the U.S. military reduce conflict.
Zak is frequently interviewed in the media on topics ranging from economic policy to romantic relationships. [15] [16] His 2011 TED talk on oxytocin and trust has gained over a million views. [17] He was named by Wired magazine as one of the 10 Sexiest Geeks in 2005. [18] Zak suggests that intimate contact, using social ritual and social media such as using Twitter and Facebook raises oxytocin levels. [19] [20] He is a frequent public speaker on the neuroscience of daily life, including morality, storytelling, and organizational culture and writes articles for magazines and trade publication on these topics.
Zak is a member of the Screen Actors Guild and has created and voiced science dialog for movies, including The Amazing Spiderman . [21] He is a regular panelist on the Discovery Science program Outrageous Acts of Psych. News organizations often request his expertise on neuroscience. In 2016, he was featured on The Bachelor as Dr. Love on one of the main characters' dates. [22] His other TV appearances include Fareed Zakaria's GPS on CNN, the John Stossel show on Fox Business, the Dr. Phil show, TakePart Live on Pivot TV, Fox and Friends, Good Morning America, The Bachelorette, and ABC World News Tonight.
Oxytocin is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. Present in animals since early stages of evolution, in humans it plays roles in behavior that include social bonding, reproduction, childbirth, and the period after childbirth. Oxytocin is released into the bloodstream as a hormone in response to sexual activity and during labour. It is also available in pharmaceutical form. In either form, oxytocin stimulates uterine contractions to speed up the process of childbirth. In its natural form, it also plays a role in bonding with the baby and milk production. Production and secretion of oxytocin is controlled by a positive feedback mechanism, where its initial release stimulates production and release of further oxytocin. For example, when oxytocin is released during a contraction of the uterus at the start of childbirth, this stimulates production and release of more oxytocin and an increase in the intensity and frequency of contractions. This process compounds in intensity and frequency and continues until the triggering activity ceases. A similar process takes place during lactation and during sexual activity.
The trolley problem is a series of thought experiments in ethics and psychology, involving stylized ethical dilemmas of whether to sacrifice one person to save a larger number. The series usually begins with a scenario in which a runaway tram or trolley is on course to collide with and kill a number of people down the track, but a driver or bystander can intervene and divert the vehicle to kill just one person on a different track. Then other variations of the runaway vehicle, and analogous life-and-death dilemmas are posed, each containing the option to either do nothing, in which case several people will be killed, or intervene and sacrifice one initially "safe" person to save the others.
Neuroeconomics is an interdisciplinary field that seeks to explain human decision-making, the ability to process multiple alternatives and to follow through on a plan of action. It studies how economic behavior can shape our understanding of the brain, and how neuroscientific discoveries can guide models of economics.
Neurochemistry is the study of chemicals, including neurotransmitters and other molecules such as psychopharmaceuticals and neuropeptides, that control and influence the physiology of the nervous system. This particular field within neuroscience examines how neurochemicals influence the operation of neurons, synapses, and neural networks. Neurochemists analyze the biochemistry and molecular biology of organic compounds in the nervous system, and their roles in such neural processes including cortical plasticity, neurogenesis, and neural differentiation.
The ultimatum game is a game that has become a popular instrument of economic experiments. An early description is by Nobel laureate John Harsanyi in 1961. One player, the proposer, is endowed with a sum of money. The proposer is tasked with splitting it with another player, the responder. Once the proposer communicates his decision, the responder may accept it or reject it. If the responder accepts, the money is split per the proposal; if the responder rejects, both players receive nothing. Both players know in advance the consequences of the responder accepting or rejecting the offer.
Moral psychology is a field of study in both philosophy and psychology. Historically, the term "moral psychology" was used relatively narrowly to refer to the study of moral development. Moral psychology eventually came to refer more broadly to various topics at the intersection of ethics, psychology, and philosophy of mind. Some of the main topics of the field are moral judgment, moral reasoning, moral sensitivity, moral responsibility, moral motivation, moral identity, moral action, moral development, moral diversity, moral character, altruism, psychological egoism, moral luck, moral forecasting, moral emotion, affective forecasting, and moral disagreement.
Distrust is a formal way of not trusting any one party too much in a situation of grave risk or deep doubt. It is commonly expressed in civics as a division or balance of powers, or in politics as means of validating treaty terms. Systems based on distrust simply divide the responsibility so that checks and balances can operate. The phrase "trust, but verify" refers specifically to distrust.
The dictator game is a popular experimental instrument in social psychology and economics, a derivative of the ultimatum game. The term "game" is a misnomer because it captures a decision by a single player: to send money to another or not. Thus, the dictator has the most power and holds the preferred position in this “game.” Although the “dictator” has the most power and presents a take it or leave it offer, the game has mixed results based on different behavioral attributes. The results – where most "dictators" choose to send money – evidence the role of fairness and norms in economic behavior, and undermine the assumption of narrow self-interest when given the opportunity to maximise one's own profits.
Generosity is the virtue of being liberal in giving, often as gifts. Generosity is regarded as a virtue by various world religions and philosophies, and is often celebrated in cultural and religious ceremonies. Scientific investigation into generosity has examined the effect of a number of scenarios and games on individuals' generosity, and potential links with neurochemicals such as oxytocin, and relationship with similar feelings, such as that of empathy.
Emotional contagion is a form of social contagion that involves the spontaneous spread of emotions and related behaviors. Such emotional convergence can happen from one person to another, or in a larger group. Emotions can be shared across individuals in many ways, both implicitly or explicitly. For instance, conscious reasoning, analysis, and imagination have all been found to contribute to the phenomenon. The behaviour has been found in humans, other primates, dogs, and chickens.
Social neuroscience is an interdisciplinary field devoted to understanding the relationship between social experiences and biological systems. Humans are fundamentally a social species, rather than solitary. As such, Homo sapiens create emergent organizations beyond the individual—structures that range from dyads, families, and groups to cities, civilizations, and cultures. In this regard, studies indicate that various social influences, including life events, poverty, unemployment and loneliness can influence health related biomarkers. The term "social neuroscience" can be traced to a publication entitled "Social Neuroscience Bulletin" which was published quarterly between 1988 and 1994. The term was subsequently popularized in an article by John Cacioppo and Gary Berntson, published in the American Psychologist in 1992. Cacioppo and Berntson are considered as the legitimate fathers of social neuroscience. Still a young field, social neuroscience is closely related to affective neuroscience and cognitive neuroscience, focusing on how the brain mediates social interactions. The biological underpinnings of social cognition are investigated in social cognitive neuroscience.
Vasopressin receptor 1A (V1AR), or arginine vasopressin receptor 1A is one of the three major receptor types for vasopressin, and is present throughout the brain, as well as in the periphery in the liver, kidney, and vasculature.
Social connection is the experience of feeling close and connected to others. It involves feeling loved, cared for, and valued, and forms the basis of interpersonal relationships.
"Connection is the energy that exists between people when they feel seen, heard and valued; when they can give and receive without judgement; and when they derive sustenance and strength from the relationship." —Brené Brown, Professor of social work at the University of Houston
The oxytocin receptor, also known as OXTR, is a protein which functions as receptor for the hormone and neurotransmitter oxytocin. In humans, the oxytocin receptor is encoded by the OXTR gene which has been localized to human chromosome 3p25.
A serenic, or antiaggressive agent, is a type of drug which reduces the capacity for irritability and aggression.
Social emotions are emotions that depend upon the thoughts, feelings or actions of other people, "as experienced, recalled, anticipated or imagined at first hand". Examples are embarrassment, guilt, shame, jealousy, envy, elevation, empathy, and pride. In contrast, basic emotions such as happiness and sadness only require the awareness of one's own physical state. Therefore, the development of social emotions is tightly linked with the development of social cognition, the ability to imagine other people's mental states, which generally develops in adolescence. Studies have found that children as young as 2 to 3 years of age can express emotions resembling guilt and remorse. However, while five-year-old children are able to imagine situations in which basic emotions would be felt, the ability to describe situations in which social emotions might be experienced does not appear until seven years of age.

Synthetic oxytocin, sold under the brand name Pitocin among others, is a medication made from the peptide oxytocin. As a medication, it is used to cause contraction of the uterus to start labor, increase the speed of labor, and to stop bleeding following delivery. For this purpose, it is given by injection either into a muscle or into a vein.
