the crum­bling pil­lars of behav­ioral genet­ics by jay joseph

Schiz­o­phre­nia researcher Tim­o­thy Crow wrote in 2008 that mol­e­c­u­lar genetic researchers inves­ti­gat­ing psy­chotic dis­or­ders such as schiz­o­phre­nia had pre­vi­ously thought that “suc­cess was inevitable-​one would ‘drain the pond dry’ and there would be the genes!” But as Crow con­cluded, “The pond is empty.” Four years later the psy­chi­atric dis­or­der and psy­cho­log­i­cal trait “gene ponds” appear to have been com­pletely drained, and there are few if any genes to be found. Twenty years ago, how­ever, lead­ing behav­ioral geneti­cists had high expec­ta­tions that mol­e­c­u­lar genetic research would soon “rev­o­lu­tion­ize” the behav­ioral sciences.
