How do you think we learned to speak a particular language, how to behave in an environment, how to address our parents, teachers, etc.? Did we know all of these behavioral expectations when we were in the embryonic stage of our development? To know more about socialization practices in the context of the debate between nature vs, nurture, I encourage you to watch this documentary made by David Reimer. This documentary captures the nature vs. nurture debate in real life. Here is the link: https://www.youtube.com/watch?v=SLFGMWoQaCU
Note: This link may not have the full video. You may have to go part by part to watch the whole movie. Usually, parts pop up in YOUTUBE once you have initiated watching any part of the full movie.
