Overview
I've worked on a lot of topics because, yes, I have broad intellectual interests. There it is, I admitted it. Each of us, however, can be an expert in a few things only, so you'll find that nearly all my research involves modelling how inherited information moves among organisms and creates emergent evolutionary properties. While there are many differences in the data and statistics for studying various inheritance systems (e.g. genes, monkey culture, religion), my work and the work of many others is supporting that there are substantial commonalities to be generalized across them. This is particularly the case now that we have much more robust social network and phylogenetic models that can make powerful predictions about behavior, genes, and culture.

Commentaries
Matthews, L. J. 2017. Criteria for good Hilbert problems or other potentially fruitful research directions. Religion, Brain, & Behavior. Commentary of special issue on Hilbert problems for the scientific study of religion.
Summary: Applied questions may be among the most analytically challenging and fruitful for advancing the scientific study of religion. Many existing evolutionary explanations for religion do not explain religiousness specifically through adaptive reasoning.
Matthews, L. J. 2016. Mutualistic cooperation – why religion is common but saints are rare. Religion, Brain, & Behavior. Commentary on target article by C. Wood, “Ritual well-being: toward a social signaling model of religion and mental health.”
Summary: Wood provides an novel and useful linkage of how evolutionary signaling theory applied to religion may intersect with more proximate research on religion and wellness. The paper also demonstrates the tendency of evolutionary religious studies to incorrectly assume all or most religious cooperation is altruistic and all or most religious signals are costly.

Karimov, R. and L. J. Matthews. 2017. A simulation assessment of methods to infer cultural transmission on dark networks. Journal of Defense Modeling and Simulation: Applications, Methodology, Technology. 14:7-16.
Summary: Three main techniques are available for determining which of several networks most governs the diffusion of a cultural trait. These techniques include autoregression, matrix permutations, and dyadic regression with random effects. Across a broad range of conditions simulated with agent based models, dyadic regression with random effects generally performed quite well for this task, while autoregression performed poorly. We discuss applications of the method for disrupting dark networks.

Summary: Historical divergence time between languages predicts simultaneous changes among national governments in autocracy-democracy and to a more limited degree sovereign defaults, likely because language relatedness is a good proxy measure for many otherwise difficult to operationalize inherited cultural norms.

Summary: Religious violence among 16th century Anabaptists was inherited along congregational lineages, while other theological and liturgical traits spread across the network of congregation leaders.
Matthews, L. J. 2012. The recognition signal hypothesis for the adaptive evolution of religion: a phylogenetic test with Christian denominations. Human Nature. 23:218-249.
Summary: Proposes that religious beliefs, rituals, and moral prohibitions serve as recognition signals to coordinate cooperation in major world religions. The hypothesis is supported by multiple quantitative tests across major Christian denominations.

Summary: Courtship behaviors in capuchin monkeys likely function as species recognition signals to reduce hybrid offspring. This predicts punctuated evolution of changes in courtship, which is strongly supported.

Anointing variation across wild capuchin populations: a review of material preferences, bout frequency and anointing sociality in Cebus and Sapujus. American Journal of Primatology. 74:299-314.
Summary: Capuchins anoint themselves with noxious compounds in a great variety of ways, but the frequency and materials used in anointing pattern logically on the phylogeny of these monkeys.

Summary: Comparative psychology has been anything but comparative from a phylogenetic perspective. Herein, MacLean et al. explain the rewards to be gained from psychology making greater use of phylogeny, and they provide a primer in how to do it.

Summary: We provide stronger statistical support that larger body mass is associated with increased extinction risk status in extant primates. We also test, but find no support for greater extinction rates historically among primates of larger body mass.

Summary: The human migration out of Africa from which we derive most of our genomes selected for increased frequencies of 'novelty seeking' alleles surrounding a dopamine receptor gene. This article included novel and much better statistical controls for human population genetic structure.

Summary: An agent based model explicitly articulates how enhancement learning interacting with reinforcement learning can produce adaptive, neutral, and maladaptive cultural traditions. We argue that imitation and learning are not required to create robust cultural traditions.
