Schizophrenia, with its apparent genetic basis, persists despite demonstrating impaired fecundity. Although this has been considered paradoxical, a similar paradigm is observed elsewhere in nature. Honey bee colonies possess sterile task specialists whose presence can best be understood by the evolutionary principle of group selection. Group selection may be pertinent to human history and consequently schizophrenia could represent an ancient form of behavioral specialization. Shamanism and religion demonstrate some similarities to psychosis and may provide clues regarding the origins of schizophrenia.

We examined semantic vs. associational influences on word priming in schizophrenia. Tested on three occasions, subjects made speeded lexical decisions to three kinds of prime-word relationships: semantic-only (e.g., Deer-Pony), associated-only (e.g., Bee-Honey), or semantic-and-associated (e.g., Doctor-Nurse). Controls showed greater priming of words related via two relationships (semantic-and-associated) than for words related only semantically.. However, patients showed greater priming for associated-only words than for words related only semantically. Schizophrenic patients may show an associational bias, restricting semantic integration and contributing to their disturbed thinking.
