Miscarriage odds reassurer - miscarriage seems more common than it suggests?
If anyone doesn’t know what I’m talking about, it’s this:

How is it possible, that it says probability of miscarriage at, let’s say, 5w 5d is around 13% for someone under 35, not overweight BUT everything I read on any pregnancy forum is “I’ve had 2 miscarriages this is my rainbow baby” “I had a miscarriage” “when I miscarried” etc doesn’t seem like 13%, seems waaaaaay more common! Equally with just people around me, I know a fair amount of people with miscarriages, young, normal weight, healthy-ish lifestyle. Not 13%
It's a combination of confirmation and attrition bias. We intuitively seek out information that confirms out theses (confirmation bias) and people who have positive experiences tend not to talk about them so they sort of drop out of the cohort you're looking at leaving a larger proportion of people with negative experiences (attrition bias) x
