+As a good cis ally, you're told that trans people know who they are and you need to respect that [on pain of being responsible for someone's suicide](/2018/Jan/dont-negotiate-with-terrorist-memeplexes/). While politically convenient for people who have _already_ transitioned and don't want anyone second-guessing their identity, I think this view is actually false. Humans don't have an atomic "gender identity" that they just _know_, which has no particular properties other than it not being recognized by others being worse than death. Rather, there are a variety of reasons why someone might feel sad about being the sex that they are, and wish they could be the other sex instead, which is called "gender dysphoria."
+
+Fortunately, our Society has interventions available to approximate changing sex as best we can with existing technology: you can get hormone replacement therapy (HRT), genital surgery, ask people to call you by a different name, ask people to refer to you with different pronouns, get new clothes, get other relevant cosmetic surgeries, _&c._ In principle, it's possible to pick and choose some of these interventions piecemeal—[I actually tried just HRT for five months in 2017](http://unremediatedgender.space/tag/hrt-diary/)—but it's more common for people to "transition", to undergo a correlated _bundle_ of these interventions to approximate a sex change.
+
+On this view, there's not a pre-existing fact of the matter as to whether someone "is trans" as an atomic identity. Rather, gender-dysphoric people have the option to _become_ trans by means of undergoing the bundle of interventions that constitute transitioning, if they think it will make their life better. But in order for a gender dysphoric person to _decide_ whether transitioning is a good idea with benefits that exceed the costs, they need _factually accurate information_ about the nature of their dysphoria and each of the component interventions.
+
+If people in a position of intellectual authority provide _inaccurate_ information about transitioning interventions, that's making the lives of gender-dysphoric people worse, because agents with less accurate information make worse decisions (in expectation): if you have the facts wrong, you might wrongly avoid an intervention that would have benefitted you, or wrongly undergo an intevention that would have harmed you.
+
+For example, I think my five-month HRT experiment was a _good_ decision—I benefitted from the experience and I'm very glad I did it, even though I didn't end up staying on HRT long term. The benefits (satisfied curiosity about the experience, breast tissue) exceeded the costs (a small insurance co-pay, sitting through some gatekeeping sessions, the inconvenience of [wearing a patch](/2017/Jan/hormones-day-33/) or [taking a pill](/2017/Jul/whats-my-motivation-or-hormones-day-89/), various slight medical risks including to future fertility). If someone I trusted as an intellectual authority had falsely told me that HRT makes you go blind and lose the ability to hear music, and I were dumb enough to believe them, then I wouldn't have done it, and I would have missed out on something that benefitted me. Such an authority figure would be harming me by means of giving me bad information; my life would have been better if I hadn't trusted them.
