Behaviour Genetics Quotes & Sayings

Unfortunately, psychologists know much less about how the environment influences a person's personality than is commonly assumed. People often talk as if the environmental effects had been well understood for decades, and the new discovery was that there were genetic effects too. In fact, nothing could be further from the truth. The area of environmental influences on personality is a morass of unsupported or poorly tested ideas, and, ironically, it is behaviour geneticists who have brought the most progress to the field. The irony is that behaviour genetics was founded in order to discover heritable influences on human behaviour. The methods such studies use, however, also allow us to identify non-genetic influences, and say quite a lot about them. — Daniel Nettle
