and aired on NBC on Wednesdays at 9:30 p.m. throughout its brief run. Broadcast during a time of the year when television viewership was low and criticized as an uninspired show with unlikeable characters, The Kallikaks never had much of a chance to succeed. Only five episodes were produced, the last one airing on August 31, 1977. Trivia The name of the family in the series title would seem to have come from The Kallikak Family: A Study in the Heredity of Feeble-Mindedness which was a 1912 book by the American psychologist and eugenicist Henry H. Goddard.
