Here are some papers from my reading queue. Four readings on human culture, behavior, and evolution, and one feature (set of readings) on Open Science.
Here are four readings from the reading queue on human culture, behavior, and evolution. The picture below (only tangentially related to the first paper) is from .
The first paper  is on the genetic architecture of economic and political preferences. Using a SNPanalysis, the authors demonstrate that such traits have a polygenicarchitecture (e.g. many genes, small effect size for each). Studies that are underpowered (and no one really knows what the appropriate sample sizes should be) can potentially generate many false positive associations between genes and behavior.
The second paper  presents us with a premise that equates (or perhaps confounds) the psychophysiology of political ideologies with the roots of more general ideological bias. Are we really looking at "natural" differences between liberals and conservatives? Or does this simply demonstrate that high-profile social issues with already polar liberal and conservative positions  are undergirded by strong emotional responses? The standard evolutionary psychology explanation is a bit contrived as well. But it goes well with the previous article.
Crossmodal and cross-cultural comparisons, unite! In this study , people from several different cultures were asked to make both "congruent" and "incongruent" associations between smells and colors. The authors come to the conclusion that cultural context through experience has both statistical (covariance) and semantic (linguistic) components.
The fourth article  is a gateway article to several recent studies in the area of neuroplasticity. The gateway leads to the work being done in the laboratory of Michael Stryker . Learn about the "neural volume control knob" and much, much more.
.....And An Open Science Argument
Here are some additional readings on networking and open science from my reading queue. The first is a paper on the life-cycle of a preprint on the arXiv  The top image is Figure 2 in the paper. The other two readings advocate for the use of open access protocols and social media to disseminate research  and counter cultural biases towards keeping research behind laboratory doors .
