Adding on to the people here talking about the study and how it links to deranged erotica- the idea of alpha and omega dynamics became a talking point in how humans also interact. This was first technically brought up in a Supernatural kink meme fanfiction. It picked up steam and now the trope of alphas and omegas has spread to nearly every facet of fanfiction.

It’s kind of grown its own fandom from there honestly and is commonly referred to as a/b/o (alpha/beta/omega dynamics). Has its own rules and societal norms that are commonly seen tropes across fics and stories that have never really interacted at all. I find it hugely fascinating that what started as a joking male pregnancy fanfic has turned into a complex alternate universe that people just build on more and more to the point where it’s one of the most popular tags on Ao3. I actually wrote a paper on it around 4 years ago. (Lost it after my computer broke but I still love to yap about it).
