You are casting doubt on a study because of the perception of the possibility of misinformation on the part of some participants without a shred of evidence tied to the study. That is one teeny tiny step above "people are saying" as a proof. And just as convincing as evidence.
Not really.
We are casting doubt on the validity of the study as a representation of the broad reality.
Of the 1000 late term abortions up to the survey, 972 people were ignored or disinterested or both. The survey only involves the tiny few willing and able to participate. That's nothing like a representative sample.
It's a big problem for most such research, it's much worse when it's a deeply personal experience and a hot button issue.
