The Pink Tax on Credibility

You've probably heard of the pink tax. It's the extra cost women pay for products that are functionally identical to men's versions: the razors, the shampoo, the dry cleaning, the sanitary products. Same thing, different packaging, higher price. Women pay it automatically, often without noticing, and the market has decided that's just how things work.

But there's another version of the pink tax that nobody puts on a price tag. Women pay it in credibility, every time their interests are used as evidence that they don't belong in serious spaces. Every time a hobby is treated as proof of a non-scientific mind. Every time being attractive is read as being decorative. It's levied quietly and consistently, and most of us have been paying it so long we've stopped noticing that too.

Let's start with knitting, and what we've decided it means.

The hobby tax

A knitting pattern is a programme. It has variables, conditionals, loops, and error-handling. The knitter reads it, executes it, debugs it when something goes wrong, and iterates until the output matches the specification. If a computer science student described their coursework in these terms, we'd nod along. When a woman describes her weekend hobby, we say "how lovely." Same cognitive work. Completely different cultural weight. That gap is the tax.

Crochet is structural engineering. The tension, the geometry, the load-bearing logic of how stitches interlock to create form. There is real mathematics in every granny square. We just don't call it that, because the person holding the hook is usually a woman, and the thing being made is usually soft and domestic and therefore, we have quietly decided, not serious.

And don't get me started on skincare.

Every woman who has built a skincare routine has done applied chemistry. She has navigated pH levels, emulsification, the order in which actives should be layered to avoid destabilising each other, and the difference between what a moisturiser claims to do and what the ingredient list actually suggests. She has read labels, cross-referenced ingredients, and made evidence-based decisions about what to put on her body. We call this "being vain." Chemists call it formulation science.

The word "hobby" is doing a lot of political work in this culture. When a man spends his weekend building a computer from components, we call it a passion. When a woman spends hers perfecting a skincare routine or finishing a crochet project, we call it a pastime. The knowledge is the same. The tax rate is different.

The woman who made chemistry go viral

Dr Michelle Wong understood something that the scientific establishment had missed entirely: beauty was one of the best entry points into science that existed, and nobody was taking it seriously. That was the tax at work too, just at the institutional level.

Wong is a Sydney-based chemistry PhD and cosmetic chemist who started her blog Lab Muffin Beauty Science in 2011, frustrated that accurate, accessible explanations of the science behind beauty products were almost impossible to find online. What she found instead was a sea of misinformation, being consumed by millions of people who were genuinely curious and completely underserved.

She didn't dumb it down. She translated it, which is a completely different thing. Her audience learned about surfactants, UV filters, retinoid chemistry, and skin barrier function because the context was something they already cared about.

Here's the proof that beauty science isn't a lesser field: early in the COVID-19 pandemic, when homemade hand sanitiser recipes were spreading faster than the virus itself, it was a beauty science account that went viral explaining why most of those recipes didn't contain enough alcohol to actually work. When the world needed urgent applied chemistry communication, Lab Muffin delivered it to millions of people. Wired Magazine has since called her "the face and voice of beauty science." Her work has been cited by the New York Times, the Atlantic, and ABC News.

Wong has noted that even now, beauty science is often treated as a lesser discipline, despite being directly grounded in chemistry and biology. She went on to co-found BeautySciComm, a social enterprise dedicated to improving the quality and reach of accurate beauty science content. The irony is that the field being dismissed as trivial is the one reaching people that traditional science communication never could.

That's what the hobby tax costs us. Not just the women who pay it, but everyone who might have benefited from what they had to offer.

The credibility surcharge

If the hobby tax is what women pay when they're seen as too feminine to be serious, the credibility surcharge is what they pay when they're seen as too feminine to be believed. Same root, sharper edge.

In 2015, a software engineer named Isis Anchalee Wenger appeared in a recruiting advertisement for her company and was immediately targeted online for being too attractive to plausibly be an engineer. She responded by starting the hashtag #iLookLikeAnEngineer, which went viral because so many women had a version of the same story ready to go.

In 2018, a popular tech Instagram account posted a photo of Lyndsey Scott, a former Victoria's Secret model, noting she could program in Python, C++, Java, and several other languages. The comments were a masterclass in motivated disbelief. People wrote things like "yeah she can write Hello World." Scott responded by listing her credentials: over 27,000 points on StackOverflow, a computer science degree from Amherst College, and her role as lead iOS engineer at a fast-growing company. Then she asked why 41% of women in technical careers drop out due to hostile work environments. Nobody had a good answer.

In 2023, a tech conference called DevTernity was found to have listed fake female speakers with AI-generated headshots across four years of events. When investigators dug into the timeline, they found that the first fake female speaker had been added to the website within hours of a public complaint about the all-male lineup. The organiser had decided it was easier to invent a woman engineer than to find one, or to believe that the ones who existed were worth platforming.

Three incidents across a decade. Three different forms of the same surcharge. Pay up, or we won't take you seriously. And even when you pay, we might not take you seriously anyway.

The women who refused to pay

What's remarkable about the women pushing back on this isn't that they chose science over femininity. It's that they refused to accept the choice was on offer.

Danica McKellar is best known as an actress, but she is also a summa cum laude mathematics graduate from UCLA and the co-author of a published mathematical theorem that bears her name. She started writing maths books for middle school girls after speaking before Congress about why girls specifically start disengaging from maths during adolescence. Her diagnosis was that the problem was cultural, not cognitive: girls weren't failing maths, the framing of maths was failing girls. Her books, including Math Doesn't Suck and Kiss My Math, used the texture of girls' actual lives as the entry point into algebra and geometry. The maths was identical to what you'd find in any textbook. The framing was not, and that was entirely the point. She wasn't lowering the bar. She was removing the toll booth.

Cristine Rotenberg, known online as Simply Nailogical, built one of YouTube's most popular beauty channels while simultaneously working as a crime statistics analyst at Statistics Canada, where her research included trends in sexual assault reporting. She then launched her own nail polish brand, Holo Taco, which sold out its initial collection within two hours. In 2021, she founded a permanent scholarship at Carleton University for students pursuing academic and creative goals. She has said publicly that she hoped young girls watching her could see it was possible to be taken seriously as a professional while still having a creative life outside of work. The nail polish and the data analysis were never in competition. She just declined to let anyone convince her they were.

Neither of these women is interesting because they're "surprisingly" intelligent for someone who likes pretty things. They're interesting because they never accepted the premise that pretty things and serious thought were in opposition. They walked straight through the toll booth without stopping to pay, and built something on the other side.

So what's actually leaking?

We talk about the leaky pipeline in STEM as though it's a mystery. Women enter, women leave, and somewhere in the middle, something goes wrong. We fund studies, run mentoring programmes, and write concerned LinkedIn posts.

But the pipeline doesn't leak randomly. It leaks at very specific points, and those points tend to share a common feature: a woman is taxed one too many times and decides the fare is no longer worth it.

It happens when a girl's interest in beauty or fashion or craft is treated as evidence of a non-scientific mind, rather than as a potential entry point into chemistry, engineering, or mathematics. It happens when a woman in tech is told, implicitly or explicitly, that being attractive means she must be decorative rather than functional. It happens when a conference would rather generate a fake female speaker than invite a real one.

So here's what we can actually do about it.

Stop treating feminine interests as the opposite of serious ones. When a girl tells you she loves makeup, ask her about the chemistry. When she talks about knitting, ask her about the maths. When she builds a skincare routine, tell her she's doing formulation science, because she is. The entry point matters enormously, and we have been throwing away perfectly good entry points for decades.

Call out the credibility surcharge when you see it. When someone implies a woman is too attractive to be competent, too feminine to be technical, too interested in soft things to understand hard ones, name what's happening. It's a tax. It's unfair. And unlike the one on razors, this one we can actually refuse to collect.

Celebrate the women who refused to pay without making their refusal the most interesting thing about them. Danica McKellar is a remarkable mathematician who also happens to be an actress. Cristine Rotenberg is a rigorous data analyst who also happens to love nail polish. Michelle Wong is one of the most effective science communicators working today, and her platform is beauty. Their femininity is not a plot twist. It's just part of who they are.

The pipeline leaks because we keep telling women, in a hundred different ways, that they don't quite fit. We have the power to stop saying it. We can decide that the serious framing we built around STEM was a choice, not a law, and that we're allowed to make a different one.

The pink tax on credibility is real. One that we can all stop paying and stop charging.
