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.
