The answer to this question is a scientific literature that looks very different indeed to the existing one. In his letter, James exploits the complex nature of behaviour genetics to sow confusion about what geneticists have found. James concedes that genes influence height, but then denies that the same is true for psychological traits. Yet the evidence for both inferences comes from exactly the same scientific methodology. All kinds of behaviour- genetic investigations (twin studies, family pedigree studies, adoption studies, and newer DNA-based studies) show consistent results when it comes to height and to psychological traits such as IQ, personality, and many other psychological measures [links can be found with the online version of this letter, via http://thepsychologist.bps.org.uk/debates]. James refers to Robert Plomin telling The Guardian ‘I have been looking for these genes for fifteen years and I don’t have any’, but this is an out-of-context quote mine. To be clear, we can know that a trait is genetically influenced (from methods such as twin studies) without knowing the specific genes involved (knowledge about which comes from different methods, such as genome-wide association studies). Thus, Robert Plomin is noting that, whereas we know that many psychological traits are strongly heritable, we do not yet know many of the specific genes involved genetic results are on the way. Since we are only at the beginning (the reason for this is that very large studies are needed to of our use of genome-wide association studies, and since very have the statistical power to detect specific genetic associations; large samples are needed to detect the very many genetic these take longer to put together than the average study). There variants that relate to psychological traits, nobody sensible is nothing contradictory or surprising about this. should expect that we would know a large proportion of them In any case, James is out of date: genome-wide association by now. Just take a look at Figure 1 in the 2014 Nature article studies in 2014 and 2015 have uncovered specific genes related from Jonathan Flint and Marcus Munafò (tinyurl.com/zj4ypld). to educational performance, to IQ, and to the personality trait As sample sizes have increased, so have the number of genetic of neuroticism.
