Last week – April 25 – Facebook posted the 2018 first-quarter data on revenues and users (here the original post from Facebook.) The perhaps unexpected take-home message is that, in spite of the Cambridge Analytica data scandal, everything seems to go well with the social media. In particular, monthly users continued to grow at the expected rate (see the graph below – original here).
In 2013 I took the time to collect some data about the spread of a story about Oreo cookies. According to it, scientists demonstrated that Oreo cookies are as much, or possibly more, addictive than cocaine. The story spread and faded very quickly, in a couple of days in October 2013, but was reported by hundreds of English language media outlets, including prominent ones such as the Huffington Post or the Guardian.
I am organising a one-hour theme session at the inaugural conference of the Cultural Evolution Society that will take place in Jena in September. The outline programme of the conference has been just published on their website. The session – “Cultural Evolution in the Digital Age” – is scheduled for the first day, Wednesday the 13th, in the morning. Plenty of other interesting talks and events all throughout the conference (but of course I am quite biased…). Below the excellent abstracts of the three talks that will constitute the session. See you in Jena!
The complexity of some cultural domains, such as technology, seems to be linked to population size. This makes intuitive sense: after all, we have iPhones and rockets, whereas hunter-gatherer societies do not. How does this work, however, for other, non-technological, cultural domains? Western stories are not more complex than Aboriginal Australians ones (I guess). What about religions, or kinship systems?
The next EHBEA conference in Paris will include a “satellite meeting” on cultural attraction theory: Cultural Evolution by Cultural Attraction: Empirical Issues
I will give a talk titled Three predictions for cultural attraction theory. Below the (tentative) slides. If you cannot wait, the three predictions are:
- lo-fi copying is more significant than hi-fi copying in cultural transmission
- domain-general social influence (context-biases) is not very important
- culture is a matter of global, often neutral, traditions, more than local, generally adaptive, differences
