Considerable hard data have emerged on the scale of misconduct. A metastudy (D. Fanelli PLoS ONE 4, e5738; 2009) and a detailed screening of all images in papers accepted by The Journal of Cell Biology (M. Rossner The Scientist 20 (3), 24; 2006) each suggest that roughly 1% of published papers are fraudulent. That would be about 20,000 papers worldwide each year.
