Deacon’s Dilemma and the origins of pairbonding
Humans have an unusual mating system: pairbonds nested within very large social groups. We share this arrangement with a very small number of other mammals (notably hamadryas and gelada baboons), although this arrangement is common in colonially nesting bird species. The proximity of rivals creates immense problems for pairbonded males and females, and raises questions as to why this social arrangement evolved and how it is maintained. I shall argue that this mating system is a response by females to the stresses (the ‘infertility trap’) created by living in very large social groups when these are necessitated by high predation risk. I shall suggest that these arrangements require the evolution of specialised cognition (self-control and triadic differentiation) if they are to be evolutionary stable, a process that necessarily involves multilevel selection and the trade off between different cointributions to fitness.

RELIC: Uniting the Triangles, Stories, and Contexts of Love
RELIC (REal Love In Context) is an integrative attempt at a comprehensive theory of love that takes into account three elements. These elements are the components of love, the stories of love that generate these components, and the ecological contexts that interact with the components and stories. The three components of love (the “triangle of love”) are intimacy, passion, and commitment (Sternberg, 1986). Different combinations of the components yield different types of love. Relationships tend to be more successful as a function of whether people have both larger and more closely matching love triangles. This theory has been validated cross-culturally in 25 countries and 34 languages. Partners not only have actual triangles for their relationship, but also ideal triangles and action triangles. Relationships succeed or fail not only because of matching triangles, but also, matching stories. From their earliest days, people form stories (e.g., fairy-tale story, business story, horror story) of what they ideally would like love to be. They then seek out someone whose conception of what it means to love matches, to the extent possible, their own. People have a hierarchy of stories, ranging from more to less preferred. Relationships are more successful when people have matching profiles of stories. This theory has been construct-validated. Love also occurs in ecological contexts, such as of the microsystem (family, work), mesosystem (interaction of microsystems), exosystem (societal institutions), macrosystem (cultural institutions), and chronosystem (secular time of relationship). These systems can either facilitate, impede, or destroy love.

Love across the lifespan
While we know a great deal about how relationships are formed and maintained, research to date has focused almost exclusively on young adults; we know relatively little about the psychology of partner choice and romantic relationships in later life. Today, however, more older adults (eg aged 50+) are seeking romantic partners than at any point in human history; this is driven by demographic shifts such as an ageing population, higher divorce rates, and increasing societal acceptance regarding re-partnering after bereavement or relationship breakdown. Current theories of partner choice are inappropriate for understanding such later-life relationships because they are based on the needs and desires of young adults. Thus, advancing knowledge on partner choice and attraction among older adults will require new methodological tools and a reassessment of theoretical frameworks. In this talk, we will present these issues in light of existing data and introduce insights from a scientifically informed dating advice programme specifically designed for older adults.

How sociality strengthens pair-bonds among Himba pastoralists
Unlike any other species, human pair-bonds are adapted to exist within a multi-layered social world. Pair-bonds form the glue that binds us into the complex societies we live in today, but in turn, our societies shape, buffer, and transform our relationships. Often science ignores this context, with a kind of Darwinian tunnel vision that reduces the study of mating to individual preferences and strategies. In this paper, relying on 15 years of ethnographic fieldwork with Himba pastoralists, I will demonstrate how integrating the social scaffolding that surrounds our pair-bonds provides a clearer picture of how relationships actually work. Using a combination of quantitative and qualitative data, this paper will cover three examples of how broadening out from the dyad affects relationship quality: (1) reliance on natal kin for post-marital support, (2) the integration of lovers to meet needs and distribute resources, and (3) use of community networks to mitigate conflict. The data will show that the strong, enduring relationships that Himba maintain outside of marriage help them to navigate their romantic relationships and buffer them during difficult times.

Higher individualism predicts lower intensity of experienced love: Data from 91 countries
Romantic love is a near-universal human experience. However, while it transcends cultural boundaries, its intensity varies significantly across individuals and societies. We hypothesize that this variability is partly driven by socio-cultural factors, particularly individualism—a cultural orientation prioritizing personal goals over group interests. As individualism continues to rise globally, its implications for romantic relationships remain underexplored. Here, we address this by examining the link between individualism and romantic love in two large-scale cross-cultural studies. In Study 1, we collected data from a convenience sample of 61,067 partnered individuals from 81 countries. In Study 2, we selected nationally representative samples from 50 countries, with controlled distributions of gender, age, and residential area (N = 6,620). The results were consistent across both studies—as individualism increased, both men and women reported lower levels of experienced love. In Study 2, individualism was additionally linked to a lower expressed desire for love, suggesting that individualism may erode the perceived importance of love. As people become increasingly individualistic, our findings provoke questions about the future of romantic love. They also carry implications for societal challenges such as rising divorce rates, fertility issues, and depression—all of which have been linked to unfulfilled or unhappy love.

Paternal care in Chinese families: Transitions, dilemmas, and privileges
Chinese fathers have been traditionally described as unmotivated or incapable of expressing love and care towards their children, although recent studies revealed that Chinese fathers – at least the relatively privileged urban middle-class ones – are willing to build emotional bond with their children by expressing warmth and affection (albeit often in culturally appropriate covert ways) (Li, 2020). The intensive parenting discourse and rising feminist sentiment also call for fathers’ active participation in childcare. At the same time, Chinese fathers are increasingly constrained by workplace demands and (a lack of) policy support, resulting in limited time investment in child-rearing and inadequate childcare skills. In such sociocultural contexts, Chinese fathers need to navigate the gap between fatherhood culture and conditions as they make sense of their own parental role. The present study explores Chinese fathers’ understanding of good care. Fourteen self-nominated and other-recommended active fathers and seven of their partners from various regions in China participated in semi-structured interviews, during which they described their daily routines, caregiving tasks, support received and expected as caregivers, and elaborated on their understanding of good care. Their narratives revealed that, whereas fathers resemble mothers in their shared emphasis on sincere devotion to child development and the importance of empathy, fathers also expressed a need for social recognition of their caregiving roles and a critique towards the intensive parenting culture. Chinese fathers’ imagined good care is a field where they both enjoy gender privilege and suffer from patriarchal norms.

Love across cultures: insights from indigenous societies for evolutionary theories
Love is a universal human experience, yet its expression and function are shaped by both biological and cultural contexts. Our research, conducted in traditional societies across Africa, Amazonia, Pacific Islands and the Himalayas, shows that intimacy, passion, and commitment—the core components of love—are recognized and valued across diverse populations. These studies reveal that love not only guides partner choice and relationship dynamics but can also influence reproductive outcomes, suggesting an evolutionary function by enhancing fitness. At the same time, cultural practices, such as arranged versus free-choice marriages, shape how love is experienced and expressed, without altering its fundamental presence. By examining both cross-cultural patterns and fieldwork in small-scale societies, our findings address long-standing questions about the universality and adaptiveness of romantic love, highlighting the interplay between human nature, culture, and evolution in shaping how love is experienced worldwide.

Neural Reward Systems as a mechanism in human love
What is love? Why do fools fall in love? We all know that early-stage, intense romantic love is usually associated with euphoria. Also, later stages of love, called “attachment,” are associated with positive feelings of happiness and comfort. One idea is that these positive associations are part of the human reproductive strategy as humans pursue, and stick with, preferred mates; it is part of the human species survival strategy; thus, we evolved to fall in love and the brain’s reward system is an essential part of evolution’s design. For groups and individuals who are in love, brain imaging studies have identified the dopamine and opioid-rich ventral tegmental area (VTA) reward system in the brainstem as an area involved in romantic feelings. The VTA activation was replicated in New York, London and Beijing, suggesting that it is cross-cultural, as is romantic love. The activation of the brainstem drive and reward system that appeared early in evolution supports the idea that love is a developed form of a mammalian drive to pursue preferred mates. Furthermore, heartbreak is a time when love is more passionate than ever, and brain imaging studies show an extensive involvement of the VTA and forebrain reward systems like the nucleus accumbens. Other studies see these same systems activated in cocaine addiction. Love may be a necessary natural addiction for survival of our species that, indeed, induces euphoria as a reward that keeps love going, and also keeps individuals safe with the protection of another.

Biological synchrony in relationships
As relationships mature, partners share common goals, improve their ability to work together, and experience coordinated emotions. In my talk, I will highlight work in monogamous prairie voles that reveals complex biological alignment between partners using monogamous prairie voles. Specifically, we find evidence of matching neural activity in interacting voles, which is stronger between bonded individuals than with an unknown vole. Using single cell sequencing, we also observe transcriptional concordance between partners, providing a gene expression signature associated with pair-specific behaviors. Together, this work delineates how social relationships change the brain to facilitate connectedness and help pairs effectively navigate the world together.

Examining the neural and genetic correlates of romantic love
In recent decades, scientists have made significant advances in clarifying some of the neural and genetic mechanisms that underly pair-bonding and attachment processes in humans. Access to relatively novel techniques—such as fMRI, EEG, and virtual reality—as well as animal studies have provided a platform for identifying the physiological correlates underlying pair-bonding. Also, innovations have promoted the investigation of culturally relevant contexts in the study pair-bonding, such as online dating. Unique to humans, and sometimes coinciding with pair-bonding, is the complex phenomenon of romantic love: a basic human motivation involving an intense desire to be united physically, cognitively, and emotionally with a beloved partner. In this talk, I will provide an overview of my research on the neural and genetic basis of romantic love. Also, I will highlight some recent and important discoveries in the science of love and pair-bonding, highlighting the neural and genetic factors that scientists have found to play a critical role in the formation and maintenance of pair-bonds and other attachment relationships. Finally, this talk will discuss possible future directions for the science of love.

In sync or out of step: Gender differences in the co-regulation of daily closeness in couples
Romantic relationships function as dynamic interpersonal systems where partners' behaviors and emotions influence one another over time (Butler & Randall, 2013). Previous research has shown that such dynamics, including physiological linkage (Kuelz & Butler, 2020) and emotional coregulation (Sels et al., 2020), are associated with relationship outcomes. This pre-registered study examined how daily closeness co-regulation patterns predict relationship satisfaction among couples. Using a 14-day daily diary study across four waves (N=997 couples), we employed the coupled oscillator model using the rties package (Butler & Barnard, 2019). Latent profile analysis identified two distinct co-regulatory profiles across all waves. Profile membership predicted relationship satisfaction in waves 1 and 4, with Profile 2 showing higher satisfaction than Profile 1 (Wave 1: b = 0.255, p < .001; Wave 4: b = 0.173, p = .005). Significant profile-by-gender interactions emerged in waves 3 and 4 (Wave 3: b = -0.083, p < .001; Wave 4: b = -0.115, p < .001), indicating that profile effects differed by gender. Closeness levels strongly predicted satisfaction across all waves (b = 0.047-0.049, p < .001) regardless of profile or gender. These results indicate that while absolute closeness consistently predicts relationship satisfaction, dynamic co-regulation patterns may have gender-specific effects that vary over time. This highlights the importance of considering gender differences when studying relationship processes and suggests that interventions might benefit from acknowledging that men and women may respond differently to various patterns of emotional coordination.

Dynamics of love across the transition to parenthood: a longitudinal study of psychological changes in couples
The transition to parenthood represents a pivotal life stage, accompanied by profound psychological, biological, and social transformations. Parenthood entails new responsibilities that reshape daily routines, social networks, and relationship dynamics. The present study aimed to provide a comprehensive analysis of changes in romantic love during the transition to parenthood. Our longitudinal design included both male and female participants, as well as childless controls, allowing for a nuanced understanding of the psychological processes associated with this life transition. The study sample at T1 testing comprised 312 nulliparous couples, with women aged 20–30 years at baseline. Participants were assessed eight times at approximately six-month intervals, enabling the evaluation of temporal patterns in love across different phases of pregnancy and early parenthood. We examined the trajectories of love intensity over time, with particular attention to couples who conceived during the project. Results are discussed in light of existing research on the transition to parenthood, highlighting both normative emotional shifts and individual differences. Our findings have implications for psychological interventions tailored to the emotional challenges of pregnancy and early parenthood. They may also contribute to understanding the psychological characteristics of individuals who postpone or forgo parenthood, offering broader insights into contemporary family and relationship dynamics.

Obsessive thinking about a loved one in romantic love: A 3 (psychology) + 4 (biology) assessment
Obsessive thinking about a loved one is a core component of romantic love. Individuals experiencing romantic love often think about their partners a substantial portion of their waking hours. This presentation outlines what is known about the psychology of (ie cognitions, emotions, and behaviours) and biology (ie mechanisms, development across the lifespan, evolutionary functions, and evolutionary history) of obsessive thinking about a loved one in romantic love. Obsessive thinking about a loved one is primarily cognitive but is associated with specific emotions. There is limited evidence for an effect of obsessive thinking on behaviour. Little is known about the mechanisms that cause obsessive thinking about a loved one. It appears to be present in juveniles. The functions of obsessive thinking about a loved one are uncertain. The only theory of the evolutionary history of romantic love suggests it emerged by co-opting mother-infant bonding.
