Scrutiny at the Canadian border to heighten security and simultaneously reduce type one
(false positives) and type two (false negatives) errors utilize substantial resources as well as imposing opportunity costs on Canada in terms of time and trade diversion. One maligned strategy to minimize these costs at the border has been group or racial profiling. This essay develops a pedigree system for Canadian border security which simultaneously reduces both type I and II errors while avoiding the more egregious costs inherent in racial or group profiling.

We tested whether eye color influences perception of trustworthiness. Facial photographs of 40 female and 40 male students were rated for perceived trustworthiness. Eye color had a significant effect, the brown-eyed faces being perceived as more trustworthy than the blue-eyed ones. Geometric morphometrics, however, revealed significant correlations between eye color and face shape. Thus, face shape likewise had a significant effect on perceived trustworthiness but only for male faces, the effect for female faces not being significant.
