As a matter of interest, here are the guidelines in Nature's (science journal's) advice to authors:
'Authors should use the terms sex (biological attribute) and gender (shaped by social and cultural circumstances) carefully in order to avoid confusing both terms.
Sex – refers to currently understood biological differences between females and males, including chromosomes, sex organs, and endogenous hormonal profiles. Sex is usually categorized as female or male, although there is variation in the biological attributes that constitute sex.
Gender – refers to socially constructed and enacted roles and behaviours which occur in a historical and cultural context and vary across societies and over time. Gender is usually incorrectly conceptualized as a binary (man / woman or feminine/masculine) factor. In reality, there is a spectrum of gender identities and expressions defining how individuals identify themselves and express their gender
Gender identity – an individual’s conception of self as being a man, woman, masculine, feminine, nonbinary, ambivalent, etc., based in part on physical, psychological and social factors. It is the internal experience of a gender role. There is a broad range of gender identities including, but not limited to, transgender, gender-queer, gender-fluid, non-binary, gender-variant, genderless, agender, nongender, bi-gender, trans man, trans woman, trans masculine, trans feminine and cisgender
Gender presentation – how a person publicly expresses or presents their gender identity. This can include behaviour and outward appearance such as dress, hair, make-up, body language and voice. A person’s chosen name and pronouns are also common ways of expressing gender. Others perceive a person’s gender through these attributes. Another term is “gender expression.”'
I read that and think, thank goodness I'm a physicist; but it seems reasonable, even if they missed off 'not a clue, don't really care' from the gender ID bit.
