This paper develops a simple “instant-response” model of strategic behavior where players can react instantly to changing circumstances, but at the same time face some inertia after changing action. The framework is used to reconsider the folk theorem and, in particular, the role of the key condition of dimensionality. In contrast to the discounted case in discrete time, here low dimensionality...

This commentary stresses the importance of Atran’s work for the development of a new cognitive anthropology, but questions both his particular use of Dawkins’s “meme” model and the general usefulness of the meme model for understanding folk-taxonomies as cultural phenom-

In this paper we want to establish two points of interest to Brandom’s project of analytic pragmatism.

In three experiments, we examined humans' folk physics (i.e., a naturally occurring and spontaneous understanding of the physical world), using variations of problems used to study chimpanzees' folk physics. Presented with trap-tube problems in two experiments, adult humans showed an unnecessary bias to insert a stick into the end of the tube farthest from the reward to push it out the other en...

Ailments afflicting wizarding folk are underreported in the muggle world. The recent integration of muggles and magical folk with the return of You-Know-Who (aka He Who Must Not Be Named) may result in a similar affliction of inhabitants of both worlds. We describe interesting maladies afflicting muggles and wizarding folk alike, arising from the use and misuse of magic. We also provide a basic...
