It’s hard to adjudicate between these two interpretations without more information. But one datum of interest is the fact that most respondents did not view crossing the lawn to feed the starving child as a violation of the parents’ rights. This suggests, at least, that respondents were not in this case making the distinction between the moral permissibility of an act and the question of whether that act violated someone else’s rights. And this, in turn, casts at least a bit of doubt on the idea that seeming discrepancies in their answers were undergirded by a sophisticated Rothbardian analysis of the ethics of emergencies.

2. How well do the results of these surveys represent the beliefs of libertarians in general? In each case, the respondents were drawn from attendees at the Libertarian Party National Convention and readers of Liberty magazine. Liberty was a magazine for “movement” libertarians–people who were very clear in their self‐​identification as libertarians, and enjoyed reading articles about the possibility of privatized roads, gossip about Ayn Rand’s inner circle, and the like. A very different kind of reader than you might expect from an “outreach” publication like Reason, for instance. And, of course, the kind of people who hang out at LP conventions (filling out surveys, no less!) are, well, a “different” breed as well. (As Ed Crane quipped about his experience at the 1971 founding convention in Denver, “As a libertarian, I always knew it was important to be tolerant of alternative lifestyles, but … until I went into that convention hall, I had no idea how many alternatives there were.”)

The respondents, then, were probably significantly more “hard core” than the median libertarian. And it’s probably reasonable to assume that hard core libertarians are generally more likely to agree with the NAP than the less hard core ones. If so, then the survey results probably overstate the extent of agreement with the NAP among libertarians as a whole.

3. I wonder what’s happened since 2008? My sense from conservations online and at various libertarian conferences is that the NAP might be making a comeback. Is this accurate? And, if so, what might explain it? Well, 2008 was the year of Ron Paul’s first campaign for the presidency, and his rise to stardom among libertarian youth. Paul has a long connection to the Ludwig von Mises Institute via Lew Rockwell, and my sense is that the LvMI has used this connection and its incredible web presence to draw a lot of young Ron Paul supporters into its fold. And the NAP is, of course, a central part of the “plumb line” libertarianism that LvMI seeks to defend and spread.

At the same time, 2008 was also the year in which Students for Liberty was created, and it too has enjoyed tremendous growth and success in the last few years. And, compared at least to LvMI, SFL is less closely wedded to the Rothbardian vision of libertarianism, including the NAP.

Both LvMI and SFL are diverse organizations, of course, and there are plenty of individuals in each of them for whom my generalizations will not hold. I’m painting with a broad brush here simply in order to speculate about possible large‐​scale trends in the libertarian movement. But, in the end, it’s just one guy’s speculation.

Perhaps it’s time for another survey?
