There's going to be biological differences between the genders. There's going to be biological differences between two women or two men. There's biological differences between all of us. My concern is, why are we so concerned about it? Why are we so worried about it? Why, whenever a study comes out about men do this one way and women do this one way, or men's brains and women's brains - why are we so interested in that? You know, what makes us so fascinated by differences between the sexes? And I think more often than not that interest is deeply embedded in sexism.
Look at identical twins. When you get closer, you start to see the small differences. It all depends on how much you magnify it.
If you look across a host of measures at adoption studies, fraternal v. identical twin studies, twins-raised-apart studies, the history of early childhood intervention research, naturally-occurring experiments, differences between societies, changes over history, and so forth, you tend to come up with nature and nurture as being about equally important: maybe fifty-fifty. The glass is roughly half-full and half-empty.
I think there are profound differences between women and men. In intelligence and creativity, there is no difference, but in what one loves, what one likes, the passions - there are differences.
Personal differences, musical differences, business differences, but most of all because I have a better time with my family.
Identical twins are ideal lab specimens for studying the difference between learned and inherited traits since they come from the womb preloaded with matching genetic operating systems. Any meaningful differences in their behaviors or personalities are thus likely to have been acquired, not innate.
The Role of Deliberate Practice in the Acquisition of Expert Performance”: “The differences between expert performers and normal adults are not immutable, that is, due to genetically prescribed talent. Instead, these differences reflect a life-long period of deliberate effort to improve performance.
Anybody who objects to cloning on principle has to answer to all the identical twins in the world who might be insulted by the thought that there is something offensive about their very existence. Clones are simply identical twins.
... no matter how great the differences are between men and women, the differences among members of the same sex are usually equally great if not greater.
The broadest pattern of history - namely, the differences between human societies on different continents - seems to me to be attributable to differences among continental environments, and not to biological differences among peoples themselves.
The differences between Indigenous and not Indigenous Australians can be easily attributed not to differences in their genes but to differences in the conditions in which they're born, grow, live, work and age - in other words, to the social determinants of health.
No one has found a gene for IQ. "Heritability" means that identicial twins are more similar than fraternal twins, right? Fraternal twins more similar than non-siblings. The heritability is 50 percent if your parents went to college. But if your parents never graduated high school the heritability is zero. Zero.
On consideration, it is not surprising that Darwin's finches should recognize their own kind primarily by beak characters. The beak is the only prominent specific distinction, and it features conspicuously both in attacking behaviour, when the birds face each other and grip beaks, and also in courtship, when food is passed from the beak of the male to the beak of the female. Hence though the beak differences are primarily correlated with differences in food, secondarily they serve as specific recognition marks, and the birds have evolved behaviour patterns to this end.
Genuine tolerance does not mean ignoring differences as if differences made no difference. Genuine tolerance means engaging differences within a bond of civility and respect.
The differences between religions are only differences involving the pathways that lead toward the practice of directly experiencing higher levels of perception and understanding. All religions are paths to a metaphorical mountain-top variously named Wisdom, enlightenment, self-realization, the kingdom of heaven, righteousness, etc. Differences that lead to violence and persecution are based on a corrupted relationship to the teachings and practices of religion.
Science has yet to isolate the Godiva Chocolate or Prada gene, but that doesn't mean your weakness for pricey swag isn't woven into your DNA. According to a new study of identical twins, it's less TV ads or Labor Day sales that make you buy the things you do than the tastes and temperaments that are already part of you at birth.
