So, here it’s important to know, how we decide if someone or something is good or bad? is it because of the intrinsic nature of the thing or a person, or we make our judgements in relativity. If someone is telling you that they make objective or independent decisions while being part of the society, they are clearly lying or they could just be ignorant or unaware perhaps.
At the end of the day, you think this is good or bad in comparison to something that you already know or something you have already experienced of. So this kind of establishes that truth is formed purely because of the references we have in terms of experiences or something we already know.
There’s another layer to it, like we know now we kind of make hypotheses largely because of availability heuristics or, in simple words, based on the information that is conveniently available, so when we lecture people about morality, do we really mean that this is objectively wrong/right thing to do or do we just think that meh this is in my favor it’s more convincing it should be done ?
