You can't disentangle nature from nurture with some sets of twins as they are both in play. That's part of why it's fascinating to see both with strong simultaneous reinforcement, and similarly when the "nurture" part is removed and the chances of similarities is higher than normal.
- lukas099 4y agoYes, we are lucky to have identical twins in the world if for nothing else than the scientific research they enable.
- waterhouse 4y agoSome studies look at identical twins vs fraternal twins, seeing if identical twins are more similar than fraternal. It's an excellent way to control for almost everything except the genetics.
- cperciva 4y agoThe gold standard is "separated twins" studies, looking at identical twins who are adopted away to different families at birth. Sadly for science but happily for the families involved, these are getting harder to do; the primary source of such twins used to be unmarried women who became pregnant, but between the availability of birth control and a dramatic reduction in the social stigma, far fewer children are being "hidden" by being adopted away.
