| 0:00.0 | In the 1960s, a New York clinical psychiatrist and an adoption agency conducted an experiment. |
| 0:06.0 | They separated multiple sets of identical twins and one set of identical triplets into different families to test how much personality is due to genetics or the environment. |
| 0:16.0 | None of the children or families were ever told about this. |
| 0:19.6 | The results of this experiment and other cases like it have proved to be fascinating. |
| 0:24.0 | Learn more about identical twins and triplets that were separated at birth |
| 0:28.1 | on this episode of Everything Everywhere Daily. daily. One of the greatest debates in the history of psychology is if humans are fundamentally ruled by genetics or by our environment or as it's usually described |
| 0:54.6 | nature versus nurture. If we were raised in a different family in a different place |
| 0:59.5 | and maybe a different time how different would we be? We all probably would like to think |
| 1:05.1 | that we'd be exactly the same people, but that's because we can't envision ourselves |
| 1:09.2 | being someone that we're not. One way to test nature versus nurture would be to somehow remove one of the variables. |
| 1:16.2 | There have been countless cases of people with different genetic backgrounds being raised in similar |
| 1:20.8 | environments, but what if it were possible to do the opposite? Take two people |
| 1:25.6 | with the same genetics and raise them in different environments. The only people who have the exact |
| 1:31.6 | same genetics are identical twins, and you don't really see |
| 1:35.1 | identical twins raised in different households very often. |
| 1:38.7 | To do so, you would have to separate them at birth. |
| 1:41.8 | For the longest time, there just weren't any cases like this |
| 1:44.8 | that anybody knew of. For starters, identical twins are relatively uncommon. |
| 1:49.1 | There are 32 sets of twins born for every 1,000 births, and only a third of those are identical. |
| 1:56.1 | It isn't something that's super rare, I'm sure most of us know a pair of identical twins, or perhaps |
| 2:00.7 | you're one yourself, but it's also a small minority of people. |
| 2:04.0 | Second, assuming you had twins, the number of children who are born that are put up for |
