The difference is with science the truth will eventually out. No one says science is incorruptible, but the process of science means that it generally keeps moving in the correct direction, despite normal human tendencies. The other part is that when science is found to be wrong, scientists change their assumptions based on new information. There's numerous examples of science being used for ill. Light bulbs that burn out faster because of a cabal of bulb makers, functional vaccines for diseases locked up for years unused, and mistakes like radiation poisoning of workers and people because we just didn't understand the ramifications at the time. All of these were eventually corrected by other scientists. Now specific to writing papers, paper writing is required for some educational job progress. The journals are supposed to be ethical, however this problem has been known about and pointed out numerous times by ethical scientists.
