Gloomy Prospects and Roller Coasters: Finding Coherence in Genome-Wide Association Studies

We address Turkheimer’s argument that genome-wide association studies of behaviors and psychiatric traits will fail to produce coherent explanations. We distinguish two major sources of potential incoherence (heterogeneity and complexity), showing how they independently threaten coherence and considering how they are being and might better be addressed with protein and other databases and network tools.
