Why do religious leaders observe costly prohibitions? Examining taboos on Mentawai shamans

Why do we observe a small but nonzero cosmological constant?

The current observations seem to suggest that the universe has a positive cosmological constant of the order of H 2 0 while the most natural value for the cosmological constant will be L−2 P , where LP = (Gh̄/c3)1/2 is the Planck length. This reduction of the cosmological constant from L−2 P to L −2 P (LPH0) 2 may be interpreted as due to the ability of quantum microstructure of spacetime to rea...

Why We Do Things Differently: Leaders and Followers?

Why aren't we all hutterites? : Costly signaling theory and religious behavior.

In this paper I explore the psychology of ritual performance and present a simple graphical model that clarifies several issues in William Irons's theory of religion as a "hard-to-fake" sign of commitment.

Why do overqualified incumbents deviate? Examining multiple mediators.

In the modern marketplace, especially when unemployment is high, more and more Americans find themselves overqualified (i.e., possessing more competencies than the job requires).
