Information that surprises you is interesting as it exposes where you have been miscalibrated, and allows you to correct for that.
I suspect the users of LessWrong have fairly similar beliefs, so it is probable that information that has surprised you would surprise others here, so it would be useful for them if you shared them.
Example: In a discussion with a friend recently I realised I had massively miscalibrated on the percentage of the UK population who shared my beliefs on certain subjects, in general the population was far more conservative than I had expected.
In retrospect I was assuming my own personal experience was more representative than it was, even when attempting to correct for that.
I saw this on your blog and also found them surprising. 1 and 4 particularly as they contradict my own experience. Maybe we're overestimating how often people make conscious deliberative decisions in these matters? Or how much difference the additional information makes (people probably have a rough idea which food has more calories and the health conscious choose the lesser anyway).
This is one of those times I hate ethical restrictions on social research, need more controlled data.
ETA Does the calorie observation hold true in non-restaurant settings? (E.g. grocery shopping?). Possibly the social elements of restaurant purchasing override calorie concerns, but they're more prevalent in other places.
Probably. IME, when people eat in restaurants, usually it's not exactly because they want to eat lightly.
