In a successive series of models, published in Scientific Reports, we considered whether other individual-level mechanisms could potentially be mistaken for conformity, generating relations between frequency of a trait and probability to copy it that looked like sigmoids. We choose a few simple and plausible mechanisms (you can refer to the paper for details) and we found that two of them – on a total of seven tested, plus three controls – generated relations for which a sigmoid function produced a better fit than a linear one (see figure below). The codes for running all simulations (written in Matlab) are available through the Open Science Framework.

I’ve just uploaded on SocArXiv a new preprint, A cultural evolution approach to digital media, where I suggest (surprise!) that cultural evolution provides some interesting tools to analyse digital media.

One of the articles of my holiday-accumulated reading list was, given my current interest in the effects of digital media on cultural transmission and evolution (see here), Katherine Viner’s How technology disrupted the truth, a long read of the Guardian. The piece got extensive – and almost exclusively positive – attention (there are, when I write, 1,589 comments and around 64,000 shares). In fact, I found it quite hideous, and I believe it also embodies a widespread common-sense attitude towards digital technologies, and social media in particular, so I decided to write here some comments.

[I am starting to gather more systematically thoughts and materials about the topic “Cultural Evolution in the Digital Age”, including a twitter hashtag #CulturalEvolutionInTheDigitalAge where I plan to collect some recent – and less recent – papers, articles, discussions, etc. I hope to write at some point a more thorough introduction to this project. For now, here some extemporaneous reflections on the echo chambers phenomenon]

A few books very relevant for cultural evolution have been published in the last months.
