SEATTLE, Washington - I know I've been whining about the herd behavior of the public regarding their opinion of the "economy", but we may have finally stumbled upon a good indicator of the public's true sentiment - Playboy centerfolds. Scholars have correlated the dimensions of the playmates with the economic conditions of the time of their photo spread, and determined that in bad times, the playmates look like someone you'd hook up to the plow, and in good times they look like baby factories. This is consistent with something called the Environmental Security Hypothesis:
The Environmental Security Hypothesis says that in tough times men will prefer women who are good at production, generally older, taller, heavier, less curvaceous women with less body fat. In good times, they will prefer women who are good at reproduction, generally younger, shorter, lighter, more curvaceous women.
