Its simple - most science is bullshit as published. It is all a giant money making scheme for universities, which is not all bad since universities provide education to the masses. With that being said, I can take the same results and method, and write a conclusion or discussion to support the argument that I need to make to get my next round of funding. Its a fucked up system and Congress is to blame. If there was not such a tight squeeze on R&D funding, then scientists wouldn't pull this shit. Personally, I don't do it (army veteran before academic), but I see others pull this shit all the time. It disgusts me. I have reported several colleagues to the OIG, but nothing happens.
I feel that there is indeed a lack of ethics in today's scientific research. Animal testing has been a hotly debated topic for years, but it has not been stopped in its entirety. I believe that animals should not be subjected to scientific experiments because it is unethical to do subject them to such things.
I think there is a lack of ethics in the field of scientific research, but I think that is part of the general environment within science. I think people in this field are more concerned with answering questions and finding new discoveries, rather than worrying about the implications of these processes. After all, it was scientists who created the nuclear bomb, were they being ethical at the time?
I think scientific research is, for the most part, carried out ethically. These ethics debates have been carrying out for centuries, most by people who aren't scientists. Usually these debates are carried out by moral philosophers of science who don't actually do any science. Rather, they just sit there and babble.
I do not believe that there is any credible threat of a lack of ethics in the field of scientific research. In credible scientific endeavors, researchers must publish their findings. Those publications are then subject to peer review. Any ethical lapses would be apparent, and would be dealt with swiftly. The loss to reputation would be immediate and lasting.
I believe that the vast majority of scientists hold themselves and their experiments to the highest ethical standards, those who do not quickly find their funding cut and out of a job, I think overall scientists strive for ethical conduct and establish clear protocols on the ethics in their different experiments.
