I spent the decade I lived in New Zealand as a member of the New Zealand Skeptics. The gist of the organisation’s reason-for-being was to promote a broad-based support for the Enlightenment belief in empirical evidence. For instance, what does the data say about alternative medicine’s worth? Or taking vaccines? Or homeopathy? Take away the placebo effect and what have you got? What do double-blind randomised control studies show? That sort of thing.
