I am of course biased, but I have often been exasperated by the various "trainings", IRB processes, ethics classes, etc, that are required to run even basic psychology studies such as surveys.
Meanwhile, down the hall, the medical department is opening the skulls of mice, implanting electrodes, giving them supercancer, and then euthanizing them en masse. Often with less approval burden.
The hard truth is that it's tricky to decide what's ethical in science; we mostly allow or disallow things because they've been done that way for years, and all the added "process" is nothing but paper pushing and ass covering to quiet concerned outsiders.
What is the appropriate way to help a righteous but underpaid lab assistant find the guts to call out a process as unethical and insist that the boss’s claim that the IRB has approved it is bogus?
It also helps to always have more than one person who could call so they compete with each other to be first because they don't want to be the one seen as an accompanist to fraud.
