Ask HN: If scientific experiments aren't limited by moral, where will we be now?
If we can ignore the impact of ignoring morals in society and only talk possible scientific / sociological achievements.
Are you asking what the implications are for ignoring morals and focusing on mechanics?
If so, the first thing I would state is that all morals are purely a social construct. There is no such thing as "objective morals" because they differ between societies and cultures.
I'm also not sure what you would get out of a study just throwing some kids on an island with apes? That's super uncontrolled. Plus is this morals or research ethics we're discussing and what is the difference?
