It’s definitely a good idea to do this.
But the way you’ve set about doing it isn’t going to produce any worthwhile data.
I’m no expert on branding and market research, but I’m pretty sure that the best practice in the field isn’t having conversations with 9 non-random strangers in a lift (asking different leading questions each time) then bunging it in Google Docs and getting other people to add more haphazard data in the hope that someone will make a website that sorts it all out.
First you need to define the question you’re asking. Exactly which sub-population are you interested in? You start off asking about “the average person”’s attitude to rationality, suggesting that maybe you want to gauge attitudes across the whole (US?) population. But then you decide that the 60+ man is “outside our demographic bracket”, although your 70+ grandmother apparently isn’t.
Either way, the set of [people who work in your office building plus your grandmother] might not constitute a representative sample of the population of the USA, let alone everyone in the world. Getting people who frequent Less Wrong to ask people they cross paths with isn’t going to be a representative sample of all people—you can see that, right?
The most efficient way to answer your question is likely to be piggybacking on existing polling organisations. Now, it’s probably true that corporate marketing/branding “researchers” have a bias towards confirming what the bosses want to hear—I was just reading this Robin Hanson article about how people don’t evaluate the quality of predictions after the fact: http://www.cato-unbound.org/2011/07/13/robin-hanson/who-cares-about-forecast-accuracy/ - but still, I think it would be better to at least consider that there are organisations whose job it is to find the general public reaction to a “brand”.
You could find someone who works for such an organisation and suborn them to add an extra question to a proper survey. That way you could gather the reactions of 1000 or 10,000 demographically-representative people in a single action. Let’s not waste our time dicking around uploading meaningless data to Google Docs.
A good target in the UK would be YouGov.
I also think it’s pointless to worry about a concise definition of rationality until it’s been determined that “rationality” is in fact a good brand for public consumption. What if it turns out that the term “rationality” makes 60% of people instantly hostile? Do the research first, then start proselytising.
I find it interesting that the response to this article hasn’t overwhelmingly been about criticising Raemon’s methodology. Is that because LessWrong members fallaciously assume that attempting to measure the public’s subjective, irrational responses to a word doesn’t need to be carried out in an objective, rational manner? Or is it, as I increasingly suspect as I edit and re-edit this comment, that I’m a total dick?
Putting up a poll on Livejournal would also constitute “asking real people”. Obviously an LJ poll isn’t going to deliver a representative sample or actionable information—but then again, neither is asking 9 people who work in your building in New York.
