Behavioral Genetics Quotes

“There is a power in accepting people the way they are—our friends, partners, workmates, children, siblings, and especially ourselves. People really are born different from each other and those differences persist. We’re shy, smart, wild, kind, anxious, impulsive, hardworking, absent-minded, quick-tempered. We literally see the world differently, think differently, and feel things differently. Some of us make our way through the world with ease, and some of us struggle to fit in or get along or keep it together. Denying those differences or constantly telling people they should change is not helpful to anyone. We should recognize the diversity of our human natures, accept it, embrace it, even celebrate it.”

“Show me the science. Last I heard, gay six-year-olds remain unproven.”
― Vernon D. Burns

“We are living in a golden age of genetic research, with new technologies permitting the easy collection of genetic data from millions upon millions of people and the rapid development of new statistical methodologies for analyzing it. But it is not enough to just produce new genetic knowledge. As this research leaves the ivory tower and disseminates through the public, it is essential for scientists and the public to grapple with what this research means about human identity and equality. Far too often, however, this essential task of meaning-making is being abdicated to the most extreme and hate-filled voices. As Eric Turkheimer, Dick Nisbett, and I warned:

If people with progressive political values, who reject claims of genetic determinism and pseudoscientific racialist speculation, abdicate their responsibility to engage with the science of human abilities and the genetics of human behavior, the field will come to be dominated by those who do not share those values.”

“If Faustian restlessness is one of the defining characteristics of modern humans, then, by Pääbo’s account, there must be some sort of Faustian gene. Several times, he told me that he thought it should be possible to identify the basis for our “madness” by comparing Neanderthal and human DNA. “If we one day will know that some freak mutation made the human insanity and exploration thing possible, it will be amazing to think that it was this little inversion on this chromosome that made all this happen and changed the whole ecosystem of the planet and made us dominate everything,” he said at one point. At another, he said, “We are crazy in some way. What drives it? That I would really like to understand. That would be really, really cool to know.”

“Robert Plomin is among many who hold to the multigene view of behavioral traits and is quite sure this complexity explains the lack of success in implicating specific genes for specific behaviors. In an April 1994 article in Science, Plomin argued that all the evidence suggested that behavioral traits were not influenced by single major genes but by an array of genes, each with small effects. He views the single-gene approach as doomed to failure. While stressing the complexity, Plomin sees hope for progress in a different direction. “I’m interested in merging molecular genetics and quantitative genetics,” he says. “That’s what many of us are trying to do, not saying we think there’s a single gene and we hope to stumble on it. But rather let’s bring the light of molecular genetics into this dark alley and look for genes here. And that means we need approaches that will allow us to find genes that account for very small effects—not 20 percent of a trait’s cause, not 10 percent, but less than 1 percent. There are ways to do that. Association approaches. The Human Genome Project will speed up this sort of research.”

“In his summary of these heroic efforts on the part of the behavioral geneticists to meet this frequent objection of the environmentalists [that identical (MZ) twins develop similarly because they are treated more similarly than fraternal (DZ) twins], [Kenneth] Kendler made no mention of the complete substantiation these studies have received from the Minnesota and Swedish reared-apart twin studies, which lack the potential pitfall of different MZ-DZ upbringings in the same home. He laboriously showed that the one complaint has no basis in fact. It would seem to put to rest once and for all this one complaint and force the critics to find different ones.

This was not to be the case. For more than ten years after Kendler’s paper, opponents continued to cite the possibility of different upbringings given identicals as opposed to fraternals as invalidating twin studies. As late as 1994, the objection was raised in the pages of Scientific American. Sometimes the criticism is not alluded to directly. When other critics referred darkly to the “seriously flawed” nature of twin studies that compared monozygotic with dizygotic twins, more often than not the unnamed flaw turned out to be the one Kendler and others had refuted a decade earlier. And there is no possibility the critics who keep resurrecting this charge are unaware of the refutation. Each time the flaw is cited in print, a weary behavioral geneticist will write a letter to the editor pointing out the research that obviates the complaint, but the critics continue to make it year after year.

As an outsider, I came into this field believing scientists were simply truth seekers, men and women dedicated to discovering the functioning of the world around them, to understanding the givens. I saw them as driven by profound curiosity. It was, therefore, disheartening for me to learn that many scientists with broad reputations do not place truth at the top of their agendas and react in sadly unscientific ways when confronted with evidence they feel threatens their ideological positions. Aware of the scientific rules, they first attempt to discredit with counterarguments, but when these are shown empirically to be invalid, they simply pretend that the evidence they were unable to shoot down doesn’t exist. Such selective memory permeates the behavioral genetics debate. In the nonscientific world we have a word for such behavior: dishonesty.”
