Medical researchers should always attempt to develop effective medical treatments as rapidly as they can while fulfilling their other moral obligations. It is wrong for any company to ask its medical researchers to keep their research confidential, if failure to share the research might delay development of effective medical treatments. If the most important moral principle is to prevent human suffering, then it is wrong for medical researchers to keep their research confidential. Medical researchers should not keep information confidential if it is possible that sharing that information would prevent some unnecessary human suffering.
Doctor: It is wrong for medical researchers to keep their research confidential, even if the companies for which they work would rather that they do so. If research results are not shared, the development of effective medical treatments may be delayed, and thus humans may suffer unnecessarily.
