infers that because something is true of each individual person belonging to a group, it is true of
This answer describes the famous Part vs. Whole flaw, so if we are familiar with that flaw, we might simply look at this argument and say, "No, that was definitely not a Part to Whole move". Otherwise, we'd see that this answer is structured, infers that because X .... Y That means that X should match the Evidence and Y should match the Conclusion. Does the Evidence have a claim that says "something is true of each individual person belonging to a group"? Nope. This is the evidence: 1. the view that "we're all consumed with self-interest" implies that it's impossible to have government by consent 2. Democracy is not possible in the absence of government by consent. Neither one of those claims is saying that "something is true of each individual person belonging to a group". Since the evidence part of this answer doesn't match the actual evidence, it can't be correct. The conclusion half of this answer is also struggling, because saying that "social scientists who believe X evidently also believe Y" is not saying that something is true of a group as a whole. This answer is describing an argument that would sound like this: "Each cheerleader on the squad has too little money to afford to print a new banner. Thus, the cheerleading squad has too little money to afford to print a new banner." Or to make it sound slightly more like this argument, "Each social theorist on the committee believes that aspiring to democracy is futile. Therefore, the committee believes that aspiring to democracy is futile."
