I was looking over old discussions, and wondered: who originally came up with the notion that the "principle of least surprise" should apply to educational content? If it existed before Wikimedia, who introduced it to the image filter discussion, on what rationale?
[Personally I think it's an inanity - an education that doesn't turn your head upside down might as well be basket weaving - and it's too easily applied to shocking and outrageous concepts that children shouldn't be exposed to, like homosexuality or rights for minorities - but I could of course be convinced I'm wrong.]
