Hey, psychology degree here, who knows a good number of systems, figured I might spread some information here. Dissociative Identity Disorder isn't actually THAT rare. It's around the same percentage as natural red hair, 1.1%–1.5% of the population
. However, it's super common for people with DID to not even be aware they have DID, because it's a trauma-based disorder made to allow someone to survive--which means it's natural for the "host" alter to be unaware of the others and the trauma memories they often hold. The reason we're seeing an "epidemic" (I hate that term in accordance with mental disorders) is because DID is finally coming into the light as a real disorder, not just a plot for a movie, and a lot of people are finding that treatments for CPTSD haven't been cutting it because they actually have DID/OSDD-1. There are very VERY few psychologists who have experience in DID/OSDD-1, however, so getting true treatment is difficult and there's a lot of misinformation based off VERY old information that's very opposed to current research.
Not going to lie, some people ARE pretending to be DID/OSDD-1 as ways to dodge responsibility for their actions. In comes the notion of "system responsibility
" which is a push in the plural community to not blame their alters for a Bad Action and instead to hold their entire system responsible for the system's actions, no matter who did the Bad Action. This is heavily encouraged in the community, because it cuts off the major compliant people have about interacting with systems, and outs fakers who have been taking advantage of a trauma-based community.
I will say, that I have seen some people claiming on this forum that the current literature says to ignore the separate identities of DID/OSDD-1 self-states/alters, and to that I have to say... No.
The current literature says that doing that is actually quite harmful
, and can lead to increases in hospitalization, increase in diagnosis and severity of comorbid disorders (depression, ptsd, anxiety, etc), as well as increased risk of suicide.
An animal/non-human alter's form of therianthropy and otherkinism is often different than a therian/otherkin singlet (someone without DID) but their contributions are still valid and broaden the understanding of psychology-based therianthropy/otherkinism, as well as posing as an interesting question to the spiritual side of therianthropy/otherkinism.
If you're interested in more information, I also recommend the The International Society for the Study of Trauma and Dissociation
for learning about how the psych field is growing in terms of treating dissociative conditions. There are also several DID youtubers who have research-backed information in their videos
about their DID, because learning about a community is best done by talking to the community itself
