Two conclusions I draw from that:
* The demographic "people who are likely to read Kev Quirk's posts" is highly unrepresentative of the general population
* The subset of that who choose to answer this poll, are self-selecting and therefore motivated by a particular answer and therefore unrepresentative of the former demographic
@bignose so, conclusion: there's a built-in bias.
One would say, perhaps, a systemic bias?
