Hey Positive feedback / negative feedback

i have been reading a lot in here about the big chances of complications and im aware of them now thanks to this wonderful forum. now im not a top specialist in human psychology but wouldent it be  logical to Think that  people with minor complecation is more likely to seek support in great groups like this compered to the almost 100 % outcoms who reather just move away from the computer . all the great outcomes in here seems to make one good update and Then  moves on . what do you think ? I would love to know the "Real statistics"
