That's a "Survey Monkey" survey. Their slogan is, "See how easy it is to create a survey." It should be "See how easy it is to create a pointless and misleading survey."

I'm glad I'm not the only one who didn't recognize the names. I think people in the world of Objectivist / libertarian theory would surprised how many people do not understand even the difference between Objectivism and libertarianism, but they know they want the gov't dicking around less in their lives and businesses. They're willing to accept some risks associated with poverty and crime because they don't think the gov't does that great a job.

Sorry, but I have to pass. I looked at it. First, I do not recognize most of the names in any section. But for the "zeroeth" problem, I do not understand the question.

Am I to pick the writers who influenced me, or the ones whom I judge to be "influential" with other people?

And ... it is missing Ayn Rand who easily influenced everyone I knew on that list.
