How many bones have you broken, and are you hypermobile?

This is a poll for everyone, but I'm tagging a few specific groups to make sure I get a good sample!

Now that this poll about hypermobility and broken bones has closed, here's some results.

57 hypermobile participants. 31.6% had broken any bones, 66.7% hadn't.

145 regularmobile participants. 31.7% had broken any bones, 68.3% hadn't.

I conclude: hypermobility probably doesn't affect whether or not you break any bones, maybe?

@FionaCraig Haha, we already know how that'll go! 😜

@cassolotl ✓ I have broken ZERO bones; I’m not sure if I’m hypermobile but my EDS friends accuse me to be🧐

@cassolotl I've broken zero bones, and I'm less hypermobile than I used to be. In case that's helpful data.

@cassolotl how about I'm osteoporitic?

@geographile I don't think that changes what I want to know, really! Just pick what you would pick if you weren't.

@cassolotl Broke one, hypermobile, but I'd expect a clavicle fracture with the kind of impact I had no matter what. XD

@cassolotl I’m hypermobile, but three years ago I would have told you I wasn’t because I had no idea that having tight hamstrings, which made me feel inflexible in dance class, could happen in someone who is hypermobile (now I know it’s common). I mean, I can touch my wrist with my thumb, but I hadn’t done that since grade school because why would I, so I’d forgotten about it. I wonder how many people have it and have no clue.

@holly I bet LOTS!

@cassolotl 31.9% of those who answered NOT hypermobile broke bones versus 32.1% that answered hypermobile. How statistically unlikely is it that the two figures are in such statistical agreement??

@luc I don't know, but it doesn't seem weird to me! If being hypermobile had no effect on whether you're likely to break a bone, I would expect the results to be pretty close for each group.

@cassolotl so I got curious and wrote some code

If the true value in both populations is ~32.2% (since hypermobility has no effect, the poll said 65 out of 202 participants broke bones), then getting these results (≤0.2% cumulative error with sample sizes of 145 non- and 57 hypermobiles) should happen only once for every ~500 times you run the poll!

@luc Oooooo so it *is* unusually closely matched! :o
