It's a shame. The accepted figure for fraud is close to 2% for all scientists. 1 Of course, the least fraudulent are astrophysicists and the most fraudulent are in the biomedical field, 2/3 of the retracted papers are due to scientist misconduct (>45% alleged fraud)2 rather than to error, specially with images :'(
