Ooooooook lets do this

Doctors are to black women what police officers are to black men. That may seem controversial but I believe it to be true and I speak from personal experience.

If you've seen this TikTok you know that a 2016 study showed that 50% of medical students and residents thought that black people couldn't feel pain the same as white people.

And we learned from this video that because of a 1999 study, to this day, there's a black correction factor for the creatinin levels in black people's kidneys, meaning we're less likely to recieve a kidney transplant if needed.

So if you go to a doctor, feel you aren't getting proper treatment or they refuse the treatment you've requested, say to them the following:

If you weren’t already going to spread this advice because black women are at risk, then spread it because it’s applicable to everyone else as well, including you reading this.

Here's what I need you to do:

If you see a post with a "mature content" label, and it's 2026, DM me a link to the post.

Yes, that's really it.

I am hoping to collect several thousand such posts, so that I have a decent sized dataset. I do not care what the post is about; if it's labeled as "mature content", I want to add it to my dataset.

I intentionally haven't talked about what hypothesis I'm testing, because that would bias the submissions I get. That's also why I asked for so many.

But plenty of people have talked about my hypotheses, both complaining that I did not post them and speculating about what they might be. And between that and thinking it over, I have decided that I can talk about the "null hypothesis" without introducing bias. So here we go.

What is a "Null Hypothesis", anyways?

The null hypothesis is what you would expect to be the case if you don't find what you're looking for. If you're doing a statistics class assignment to find out if there is a relationship between a person's height and their shoe size, your null hypothesis is that there is no relationship (or at least not a meaningful relationship). If you're doing a study on whether Tumblr moderation and mature-content labeling is biased against trans women, your null hypothesis is that Tumblr moderation is not measurably biased against trans women.

Okay, so what's your null hypothesis, then?

So, we all probably think we have a good understanding of how the Mature Content Label system is supposed to work here on tumblr, right?

By default, post are "for everyone".

The author can mark a post as "Mature Content". This adds a label that displays a clickthrough (for lots of people) that says "the author has indicated...".

Posts can also be marked as "Mature Content" by Tumblr. When this happens, the clickthrough says "Potentially Mature Content", but doesn't say that the author indicated it.

That's my null hypothesis: that the Mature Content Label works the way it says it does.
