If wrongdoing is the same as intentional deceit, I would guess there are some that were not intentional, but instead driven by incompetence or simple mistakes.

If wrongdoing is the same as intentional deceit, I would guess there are some that were not intentional, but instead driven by incompetence or simple mistakes. Fraudulent/doctored images don't fall in to the incompetence/mistake category though. Some types of mistakes/incompetence: improperly applied statistics, poor experiment design, faulty logic, mistakes in data collection.
