Survivor’s bias is a logical fallacy that equates the experience of those who survived an experience with “proof” that such an experience is safe.
“I did it and I was fine.”
This is called survivors bias. The ones who would say differently are not here to tell their story. They are dead.
When stillbirth affects 1 in 160 pregnancies, it makes sense that 159 in 160 will tell you they did something unsafe and their child survived. You should still be aware of the risks of becoming that “1”
