A Guide to Gender
Gender isn't one thing you have. It's four things that got bundled together and sold to everybody as one.
This is the book behind the Genderbread Person — the illustrated model that pulls identity, expression, sex and attraction apart into four independent scales. Killermann wrote it with jokes and comics throughout, then uncopyrighted the whole thing so anyone could translate it, print it, or redraw it to say something better.

The core idea
One switch was doing four jobs
At birth someone looks at a newborn's anatomy and writes down one of two words. From that single observation, a whole package gets issued: what the child will be called, how they'll be dressed, what they'll be encouraged to want, and who they'll be expected to end up with. One data point, four predictions.
Killermann's argument is not that the predictions are offensive. It's that they are bad predictions — that identity, expression, sex and attraction are four genuinely separate questions, and that knowing the answer to one tells you startlingly little about the other three.
The Genderbread Person exists to make that separation visible in about thirty seconds. Identity in the head, expression all around the outside, sex in the body, attraction in the heart — four scales, drawn apart, so you can see that they were never one lever to begin with.
Separate
Identity isn't expression isn't sex
And none of the three is sexual orientation. Killermann repeats this often enough that it functions as the book's chorus, because collapsing any two of them is where nearly every muddle starts.
Continuous
Ranges, not tick-boxes
The fourth version of the diagram drops the boxes for graduated scales and puts an empty-set symbol at the start of each one — so agender and asexual people sit inside the model rather than in a footnote to it.
Descriptive
A map, not a verdict
Killermann is explicit that it shows how gender currently works, not how it ought to, and that it is not a tool for diagnosing anybody. It is for getting your own bearings.
How it's built
Groundwork first, gender second
The gender material doesn't start until part two. That ordering is deliberate — the vocabulary for talking about power has to be in place before the specifics will hold.
Basic Training
What social justice actually means, the cycle of oppression, how the Golden Rule goes wrong, intersecting identities, and the uncomfortable business of checking your own privilege.
Breaking Through the Binary
Gender norms, then the Genderbread Person introduced, explained, and rebuilt — identity, expression, anatomical sex and attraction each explored in turn, and the costs of a normalised binary.
Feminism and Gender Equity
The most visible contemporary gender movement, and how it lines up — and occasionally doesn't — with the broader case the rest of the book has been making.
Interactive
Take the bundle apart
Below are the four dimensions, each on two independent scales — because woman-ness and man-ness aren't opposite ends of one line, they're two separate amounts you can have any combination of.
Right now they're chained. One slider drives all eight, and the two halves of every pair are forced to be exact complements. That is the binary, working exactly as advertised. Unchain them and see what it was getting wrong.
Nothing here names you, scores you, or works out what you are — that is Killermann's own condition on the model. It only shows whether one number could have stood in for eight.
From part one
The Golden Rule has a bug in it
Killermann's sharpest chapter is not about gender at all. It's about the rule almost everybody was raised on, and the quiet substitution it performs.
The rule as taught
“Treat others as you would want to be treated.”
It installs your own preferences as the measure, then lets good intentions stand in for good outcomes. It works beautifully right up until the other person needs something you wouldn't. Which is most of the time.
The rule that survives contact
“Treat others as they would want to be treated.”
Which requires finding out — a question, not a guess. It is less elegant, it costs a sentence, and it is the entire practical difference between meaning well and doing well.
Community insights
What sticks after one read
Distilled from the book in our own words. Vote for the ones that read true.
"Gender isn't one thing you have. It's four things that got bundled together and sold as one."
"Who you know yourself to be, how you present, what your body is, and who you're drawn to are four separate questions with four separate answers."
"Each of the four is a range, not a switch — and you're allowed to sit at zero on any of them."
"Privilege isn't something you accepted. It's something you were handed and never had to notice."
"It's a map of how gender currently works, not a verdict on how it should. It was never built to diagnose anybody."
"You don't have to understand someone's gender to get their name and their pronouns right."
Action steps
Run the model on yourself before you run it on anyone
The setup steps are one-off changes to your own defaults and the systems you're responsible for. The daily ones are mostly sentences — short enough to become automatic, which is the only way any of them work.
Fill in the four scales for yourself before you use them on anyone
Identity, expression, sex, attraction — mark each one honestly, including the zeros. Almost everyone finds at least one that doesn't sit where they'd have assumed. That's the lesson, and it lands better on yourself than on a stranger.
Split the one question you've been asking as if it were two
Gender and sexual orientation get collapsed constantly, in both directions. Write out a case where you've merged them — a person, a joke, an assumption — and separate it into the two questions it actually contained.
Put your pronouns where people meet you
Email signature, name badge, video call, profile. The value isn't announcing your own — it's that it stops being a thing only trans people do, which is what makes it safe for anyone else in the thread to do it too.
Audit one form or system you're responsible for
A signup form, a spreadsheet, a booking flow, a class register. Find every place it forces a binary or demands a title, and ask whether you actually need the field. Most of the time nobody has ever checked why it's there.
Write your correction script before you need it
Three sentences: what you say when you get someone's pronoun wrong, what you say when someone else does, and what you say when you don't know and have to ask. Rehearse them once. The moment itself is a bad time to compose.
Correct and continue — one clause, no ceremony
"She — sorry, they — sent it over this morning." Then keep talking. An apology long enough to need reassuring turns your mistake into the other person's job to manage, which is the opposite of what you were going for.
Ask what someone goes by instead of deducing it
"What name and pronouns should I use for you?" is a normal question when it's asked of everyone. It stops being normal the moment you only ask the people you weren't sure about.
Swap the gendered address for one that includes the room
Everyone, folks, all, team, y'all. It costs one word and it stops sorting a room into two piles before you've said anything of substance. Do it until it's the version that arrives without thinking.
Catch which of the four you inferred from the others
You saw a haircut and concluded a pronoun. You heard a pronoun and concluded who they date. Notice the jump when it happens — that reflex is the binary still running, and it only weakens by being caught.
Say it when they're not in the room
Correcting someone in front of the person affected is easy and mostly performance. Doing it when there's nobody to be seen doing it for is the version that changes what a group considers normal.
“Gender is like a Rubik's Cube with one hundred squares per side, and every time you twist it to take a look at another angle, you make it that much harder a puzzle to solve.”
