What role do social networks – and the precise nature and structure of social interactions – play in the production of public goods and in human welfare? What about social contagion? A thread on #HNL experiments with many thousands of participants from 2010 to the present. 1/

In aggregate, the introduction of a new information regime acted as a kind of social institution, rewiring individuals’ connections even though the overall degree distribution of village-wide networks remained relatively stable. nature.com/articles/s41586-0… 11/

We demonstrate that social contagion could be experimentally induced to two degrees of separation— that is, upon a person’s friends’ friends.
This experimental result comports with much prior observational and experimental work of ours on social contagion (e.g., 2007 obesity study nejm.org/doi/full/10.1056/NE… & 2010 altruism experiment pnas.org/doi/10.1073/pnas.09… & 2015 altruism experiment nature.com/articles/nature15…).

Nature research paper: Educational intervention can rewire village social networks

We investigated the possible transformative effects of exogenous education interventions on social interactions in traditional village settings with a randomized trial, examining the connections that individuals keep, drop, or form, as well as the overall structure of village-wide networks that might arise. nature.com/articles/s41586-0… 3/

Countless development economics and public health interventions are delivered all the time in locations around the world. Our research indicates that these interventions may be inadvertently inducing changes in who is connected to whom, in ways that might either harm or benefit local populations. 2/

Inside the Swarm
New from For the Love of Science: Li Murphy talks about her incredible work on swarms of Mormon crickets, with many insights into how to be a scientist and the joys and challenges it presents. Plus the science itself is incredibly cool. m.youtube.com/watch?v=n1epUr…
