There have been rumours about anti-comics
crusader Fredric Wertham falsifying
his research for years, but now University
professor Carol L. Tilley has uncovered proof:
I'd always though Wertham meant well but was
misguided about going after comics, but the
fact that he altered his research shows he had
little respect for factual accuracy.
He used the fallacy of "post hoc ergo propter hoc" in his conclusions.
All juvenile delinquents read comics therefore reading comics must cause juvenile delinquency.
Psychology in those days was very much a pseudo-science.
