No hard data. Perhaps my experience is outdated, but given the near magical qualities ascribed to groin kicks, and the comparative success that I've seen people defend against them (regular people, not trained fighters), yes, I'd say most attackers are not likely to be overly shocked because someone tries to kick them in the gut/groin.
Can't say that I've ever watched anyone defend themselves against a kick to the groin (successfully or not). I always hear people on boards saying how "everyone knows" that high kicks are no good and that low kicks are, if not good then at least better. But I've never seen any sort of hard data about any of that. Which leaves me always wondering if what "everybody knows" is, in fact, the case. I don't know of anything that most people are "prepared" to defend against. I'm not saying you're wrong, I just don't know.
Perhaps a better phrasing would be that 'most attackers are familiar with kicks to the midsection' rather than prepared for, as prepared for implies more than just familiarity.
In what sense are they "familiar" with midsection kicks? Have they trained against them? Seen other people defend against them? Seen them on TV or in movies? It has not been my experience that people who are not trained martial artists or fighters are familiar with, expecting, or able to defend against kicks to the mid section or head. YMMV, of course.
Regarding my statement, "and kicks above the waist and spinning kicks in particular, are hard to hide," I don't have data excepting personal experience. Not to say that they cannot work; my point is that the legs being strong and possessing reach doesn't mitigate that kicking high takes inherently more time than punching high. And most attempts at spinning kicks that I've personally seen outside of competition usually end up with the kicker on the ground or off knocked off balance.
Ironically, I have seen many, many more kickers end up on the floor in competitions than in self-defense situations. Of course, I've also seen many, many more competitions than self-defense situations. The only self-defense situations I have actually seen myself involved me.
