  The present work discusses the pertinence of a 'sociotype' construct, both
theoretically and empirically oriented. The term, based on the conceptual chain
genotype-phenotype-sociotype, suggests an evolutionary preference in the human
species for some determined averages of social relationships. This core pattern
or 'sociotype' has been explored herein for the networking relationships of
young people--165 university students filling in a 20-items questionnaire on
their social interactions. In spite that this is a preliminary study,
interesting results have been obtained on gender conversation time, mental
health, sociability level, and satisfaction with personal relationships. This
sociotype hypothesis could be a timely enterprise for mental health and quality
of life policies.
