Implicit theories of intelligence were investigated via surveys of exemplars of intelligence. Study 1 was a four-sample survey of famous exemplars. These diverse samples reported a similar set of popular exemplars, which clustered into five groups. These groups represented five types of intelligence: scientific, artistic, entrepreneurial, communicative, and moral intelligence. In Study 2, the minimal overlap of intelligence exemplars with those of fame, creativity, and wisdom refuted the possibility that exemplar reports are indiscriminate or solely a result of availability. In Study 3, knowledgeable judges rated the similarity of 50 famous persons to exemplars representing each type of intelligence. All five similarity ratings predicted exemplar popularities. In Study 4, where exemplar reports were not restricted to famous people, 31% were nonfamous (friends, family members, teachers, etc.). The results indicate that five implicit types of intelligence, each represented by highly available exemplars, play a role in people’s implicit theories.

Averageness is purportedly the result of stabilizing selection maintaining the population mean, whereas facial paedomorphosis is a product of directional selection driving the population mean towards an increasingly juvenile appearance. If selection is predominantly stabilizing, intermediate phenotypes reflect high genetic quality and mathematically average faces should be found attractive. If, on the other hand, directional selection is strong enough, extreme phenotypes reflect high genetic quality and juvenilized faces will be found attractive. To compare the effects of stabilizing and directional selection on facial paedomorphosis (juvenilization), graphic morphing and editing techniques were used to alter the appearance of composite faces to make them appear more or less juvenile. Both facial models and judges of attractiveness were from the CSU-Long Beach campus. Although effect sizes for both preferences were large, the effect for averageness was nearly twice that found for juvenilization, an indication that stabilizing selection influences preferences for facial paedomorphosis more so than directional selection in contemporary humans.

The notion that birth order bears a systematic relation to personality was commonly thought to have succumbed to the formidable attack from Ernst and Angst (1983). The 1996 publication of Frank Sulloway's book Born to Rebel, however, breathed new life into a proposition that most social scientists thought was a dead horse. In response to the book, Townsend (this issue) insists that Sulloway's extraordinary measures to revive this dead horse were unwarranted. Apparently fearing that too many readers have taken the book seriously, Townsend attacks both the contemporary and historical evidence offered by Sulloway.
