[quote DadJoke]The nonsense that gender identity is a “belief” akin to belief in the soul ignores years of research which demonstrate that gender identity has a a heritable polygenic component, like sexuality and other traits, as this review of the literature shows.
The belief that you haven’t got a gender identity is the pseudo-religious one. If you are arguing that a well-established medical and psychological science is wrong, then you have a high standard of proof to reach.

DadJoke, you offered a reference to this paper also on a thread on which I had pointed to the implicit challenge – explain a way of detecting the presence of gender identity in the required sense – contained in Alex Byrne’s little article, What is gender identity?:
[ Byrne: ‘If there is some kind of “gender identity” that is universal in humans, and which causes dysphoria when mismatched with sex, it remains elusive. No one has yet found a way of detecting its presence, and verifying that it is causally responsible for dysphoria.’ ]
Here is a short(-ish) response to your claim that this challenge was answered in that paper by Polderman et al on behalf of the International Gender Diversity Genomics Consortium . It can serve here too.
-- Nowhere do the authors, or as far as I can tell, the studies they consider, offer a way of detecting the presence of gender identity, although they do assert its existence and offer, albeit somewhat warily, some suggestions of things they claim correlate with it.
A few (fairly typical) extracts to illustrate:
About half of the studies investigated “masculinity” and “femininity.” … Masculinity and femininity are usually measured with items reflecting sex-specific behaviors, feelings, or even cultural stereotypes as part of personality questionnaires (e.g., “I am often the leader among my friends”, or “I am a kind and gentle person”)
In a large longitudinal study in 7 and 10-year old Dutch twins, two items of the Child Behavior Checklist were summed (i.e., ‘behaves like opposite sex’ and ‘wishes to be of opposite sex’) to measure cross-gender behavior and cross-gender identity (van Beijsterveldt et al. 2006).
It is important to note the limitations of the instruments used to measure gender identity. We must recognize the possibility that they may conflate true gender identity with gender expression.
– Indeed we must.
A gender diagnosticity score is computed … gender diagnosticity is a Bayesian probability that an individual is male or female on the basis of gender-related indicators.
– But we might note that neither the Bayesian priors nor conditions include gender identity.
I do not have time to give a thorough critique. There is lots to say. Too much.
Just one thing, as follows. The notion of gender identity as used by DadJoke and others is essentially causal (hence the claim to scientific status, of course): ‘gender identity causes dysphoria when mismatched [how? hmm ] with sex’ etc. But in none of these studies cited by Polderman et al on behalf of the International Gender Diversity Genomics Consortium (or any others I have seen) does it ever get a specific mention in any causal role. Claims are made for its heritability, but it is only the heritability of ‘behaves like the opposite sex’, ‘sex-specific behaviours’, ‘cultural sterotypes’, ‘I am a kind and gentle person’ and the like that are even claimed to be measured.
Why not measure gender identity itself in a study purporting to be about gender identity? It must be because we have no way of detecting its presence. But, then, this means we have as much reason to believe in its existence, DadJoke , as we do in guardian angels and all the rest.
Or, DadJoke , prove me wrong. Show me where someone claims to have found a way of detecting its existence. We still have no satisfactory answer to the question, How do we detect the presence of gender identity?
.

Once again, DadJoke. Are you not ashamed to keep posting the same thing in attempted support of an assertion without paying any attention to what look like clear refutations of this assertion as well as explanations of how the article you refer to just does not support it?
The challenge stands, DadJoke. Do you have a satisfactory answer to the question, How do we detect the presence of gender identity? (Where “gender identity” is taken to be something universal in humans, and which causes dysphoria when mismatched with sex, as Byrne explains it.)
If you have an answer, it is time to give it. If not, you may think it appropriate, DadJoke , just to shut the fuck up about this and stop wasting people’s time with spurious references to productions of the International Gender Diversity Genomics Consortium.
-- Without an answer, of course, we are forced to the conclusion that there is no such thing as gender identity .
