SUMMARY:Sasha Kimel - Meatborne Xenophobia: Understanding When Disgust Fuels Outgroup Hate
DESCRIPTION:Given that animal-borne pathogens pose especially high disease risks and\, moreover\, that a growing body of research suggests that the evolved function of disgust is the avoidance of disease\, it is largely unsurprising that the consumption of non-normative meat would evoke strong disgust reactions. Yet\, it is largely unclear whether and when concerns about disease can also evoke negative reactions to third-parties who engage in such norm-violations. In a series of experiments\, participants in the U.S. were randomly assigned to learn about cuisine from another culture (i.e.\, fabricated and real) that contained a meat that was either relatively neutral (i.e.\, beef)\, disgusting due to disease threat (i.e.\, rat) or disgusting due to a combination of disease threat and the immorality of causing a cared-for animal harm (i.e.\, dog\, monkey). Our results suggest that disgust may only exacerbate negative judgements and behaviors towards third-parties when the disease threat also has a strong immorality component (e.g.\, eating of dogs but not rats) and\, moreover\, that this may increase depending on how cared-for the being is. Implications for theories on disgust\, compassion and third-party punishment will be addressed.

SUMMARY:Jaimie Krems - Tackling Friendship: Appraising\, Finding\, Getting\, and Keeping Partners
DESCRIPTION:Friends have recurrently provided social\, material\, and emotional support—helping humans meet a range of recurrent challenges tributary to fitness. But friendships are not the first type of relationship that comes to mind when thinking about research in social psychology or evolutionary social science. Moreover\, when friendships are the focus\, work typically foregrounds the friendship dyad. Taking an evolutionary approach suggests a different natural ecology for friendship psychology—one that implies the challenges of friendship are more and more complex than we might typically consider them to be. Perhaps\, then\, the challenges one must solve to reap the benefits of friendship should be thought of not (only) as two-person games\, so to speak\, but (also) as n-person games. I illustrate this by exploring several major friendship challenges—identifying good friends\, competing for friends\, and maintaining friendships. I also propose and test some of the possible means by which our social minds might meet these challenges\, toward ultimately maximizing the benefits and minimizing the costs of our sociality. \nhttps://www.kremslab.com/

SUMMARY:Richard Wrangham - Hunter-Gatherers\, Homo duplex and the Evolution of Human Groupishness
DESCRIPTION:Groupishness is a tendency to commit prosocial acts for which the pathway to\ncompensatory fitness benefits is unpredictable. It is unique to humans\, and its evolution is\nnot well understood. A difficulty is that the adaptive value of groupishness comes from\nindirect reciprocity\, which is hard to explain in societies that contain power asymmetries\nsuch that a dominant can appropriate resources at will. To date the only solution is Boehm’s\nproposal\, namely that morality was favored because allied males were selected to use\ncoercive behavior first to eliminate tyrants\, then subsequently to favor prosociality and\npunish antisociality. Using information on self-domestication\, a topic that Boehm did not\nexplore\, I present several tests of Boehm’s thesis. All are supportive\, while also modifying\nBoehm’s ideas. I conclude that a major increase in evolved groupishness began with the\norigin of Homo sapiens and the ability to execute tyrants. This process generated Homo\nduplex\, including the uniquely human tension between selfishness and duty seen in hunter-\ngatherers and other societies.

SUMMARY:Dietrich Stout - The Evolution of Technology
DESCRIPTION:For better or worse\, humans are now one of the major causal forces acting on the earth’s biosphere. Many would point to technology as the reason\, but what exactly is technology? In this lecture\, I will develop an evolutionarily grounded definition of technology that highlights three key features: material production\, social collaboration\, and cultural reproduction. Using examples from my own lab’s studies of stone tool making\, I will argue that these features implicate a wide range of perceptual\, motor\, and cognitive capacities as well as multiple channels of cultural inheritance and biocultural evolutionary processes. This perspective blurs presumed distinctions between social and individual learning that have shaped formal modeling approaches to cultural evolution. In so doing it calls into question the idea that one key capacity\, event\, or evolutionary Rubicon initiated cumulative technological evolution and a pattern of sustained autocatalytic biocultural feedback in human evolution. This interpretation is consistent with growing paleoanthropological and archaeological evidence of the multi-lineal\, intermittent\, asynchronous course of human evolution\, and presents a view of technological evolution as a complex and contingent process spanning a scale from neurons to societies and beyond. Nevertheless\, some synthesis may be possible with respect to a smaller number of recurring processes and relationships. In this vein\, I advance a “Perceptual Motor Hypothesis” proposing that human technological cognition has been evolutionarily and developmentally constructed from ancient primate perceptual-motor systems for body awareness and engagement with the world. Testing such hypotheses will require a multidisciplinary and comparative approach to identify patterned relations between contexts\, mechanisms\, and functions across diverse technological systems.
