I think that people who don't care about statistics are still likely to be impressed by vivid stories, not that I have any numbers to prove this.
I agree. But optimizing for good storytelling is different from optimizing for good science. A good scientific result would be like: "minicamp attendees are 12% more efficient in their lives, plus or minus 3.5%". A good story would be "this awesome thing happened to an minicamp attendee" (ignoring the fact that equivalent thing happened to a person in the control group).
Maybe the best would be to publish both, and let readers pick their favourite part.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
