Identifying Influential and Susceptible Members of Social Networks
"Identifying social influence in networks is critical to understanding how behaviors spread. We present a method for identifying influence and susceptibility in networks that avoids biases in traditional estimates of social contagion by leveraging in vivo randomized experimentation. Estimation in a representative sample of 1.3 million Facebook users showed that younger users are more susceptible than older users, men are more influential than women, women influence men more than they influence other women, and married individuals are the least susceptible to influence in the decision to adopt the product we studied. Analysis of influence and susceptibility together with network structure reveals that influential individuals are less susceptible to influence than non-influential individuals and that they cluster in the network, which suggests that influential people with influential friends help spread this product."

The Fed Dissenters, Or: Examining Narayana Kocherlakota’s Gut. | Rortybomb
"There it is. Job creators hate future taxes, and unemployment insurance has left our workforce weak, so don’t expect unemployment to come down anytime soon.

For all the fancy math, this logic is very similar to Fisher. ”Now suppose that, for the reasons just mentioned, p fell by 10 percent in the past three years and z increased by 0.05 during this period” is about as close to a “gut” feeling and “gut” reasoning as you can get. This appears to be how one of the most powerful people in the world for determining the future of the United States’ economy is determining his dissent from Bernanke’s position."

Career Advice: Our Failure of Imagination - Inside Higher Ed
"A career involves fitting oneself into a pre-given narrative. By contrast, being a “kind of person” does not. I want to suggest that we’d do well to conceive of ourselves in terms of “kinds of person,” “modes,” and “activities.” To illustrate this point, it might be easiest for me to refer to my own case. In my life and work, I have sought to see the basic kind of person I am — a philosopher — as manifesting itself in three basic ways — freelance writer, philosophical counselor, and educational consultant — and as unfolding in a set of finite activities."
