I don't think such a thing has ever been done, which makes the claim of a
growing number of scientists leaving the evolutionary/random mutation fold
nothing but hot air. This 'growing group of dissidents' is a self-serving
statement on the part of ICR and their minions which comforts them that
they are not as alone as they really are.
I believe (can't prove) that there are far more scientists like me, who
were YECs/antievolutionists and have now left YEC/antievolutionism than
evolutionists who have become YECs/antievolutionists.
