What do the bar represent in 3d space?
What do they represent in 3d space?!? (aggressiveduck.jpg)
Gaussian distributions.

Not every error bar represents a Gaussian, if for no other reason that most error bars aren’t symmetric.
The error bars for small sample size relative to population size are Gaussian.
Error due to a non-representative sample can have a variety of shapes, but their distribution might also be unknown. We do frequently, almost implicitly, assume unknown distributions to be Gaussian, but we should recognize that’s not necessarily a true fact about the universe.

Assuming a representative sample, the best point estimate is 1/12 (8.33%), and the 95% confidence test interval is 0.21% to 39%.

That’s the thing I doubt a team of highly skilled astronauts will be representative of the human population

I think if anything they would be biased towards having fewer allergies than normal people. Which suggests that 0.21% (1 in 500) is a reasonable bound for how rare a moon dust allergy could be.

Never really verified it but I think allergies are more common in developed countries. If that’s true, that the data is skewed in the opposite direction
