TL;DR: A prediction task to distinguish between URLs that fade rapidly following their peak of popularity and those that fade more slowly is defined, finding that the rapidly-fading information contains significantly more words related to negative emotion, actions, and more complicated cognitive processes.

TL;DR: The evolution of cooperation in social dilemmas continues to intrigue social and behavioral scientists as mentioned in this paper, revealing a bistable system in which cooperation emerges through a "drunkard's walk." Although these formal studies have yielded provocative new insights, empirical research was needed to test PAVLOV's behavioral assumptions.

TL;DR: In this paper, the power law of learning is used to explain the behavior of stochastic collusion in three social dilemma games and the analysis shows how the integration of alternative models can uncover underlying principles and lead to a more general theory.

TL;DR: Applied for the first time to iterated Prisoner’s Dilemma, neural network experiments showed that researchers may need to be much more cautious in using Darwinian analogs as templates for modeling the evolution of cultural rules.

TL;DR: In this paper, the authors argue that structural position affects not only bargainingpower but also the ability of low-power actors to organize against unequal bargaining power, and they hypothesize that collective action among low power actors is facilitated by identification with others who are structurally disadvantaged.
