Everyone was doing unethical experiments, luckily in the USA they passed the National Research Act of 1974 to make sure studies were done ethically. This study was not ethical, people that were experimented on here are a protected class. This study is clearly abuse. Crazy to think that that it was only 1974, which isn't that long ago.
The Belmont Report set out the principles for ethical research https://www.hhs.gov/ohrp/regulations-and-policy/belmont-repo...
