Reminds me of debating Bentham in high school. If the feeling of self-interest of a murderer acts upon is greater than the self-interest of someone not to be murdered, etc...
Maybe the point is not to reduce judgment to one qualitative idea.
What act exactly do people believe to be in their self-interest? Why are you claiming it's the anti-social ones and not the pro-social if the believe is not rooted on reality?
a) Internet privacy is in one's self-interest
b) Many erroneously believe privacy on the internet to be goal of terrorists, hackers, etc.
c) A subset of these people then act against their own self-interest by vocally supporting mass surveillance, or voting in candidates who do so, in the name of the apparent self-interest of safety
I also didn't say anything about pro/antisocial people... different person.
"People act to their own benefit" is an empty generalization that adds no useful information by itself and free of context like that only serves to mislead people. It's only true if "benefit" is explicitly undefined, and only useful if you contextualize it to an specific action and benefit that you can empirically determine it's validity, like in the article.
> I also didn't say anything about pro/antisocial people
The article, and the entire discussion is about pro/antisocial behavior.
I think it is a useful generalization when you possess a theory of mind, however. In low-trust environments, assuming criminal self-interest is often what keeps people safe... if you're basing your decision on a lack of information, wariness is warranted. Not every social environment is a conversational environment.
Humans are intrinsically irrational. That is a plain and simple fact. Humans operate exclusively on what they think is true instead of what is objective fact. Subjectively an individual human acts in ways that are roughly rational and coherent within their belief system and world view. The problem is that this frame of reference is entirely subjective and is only tangentially related to consensus objective reality. Assuming that you can apply your own reasoning and logic to all other humans is fallacy.
You must accept the fact that other people do not share your world view and will not act with what you, personally deem to be rationality.
