I’m commenting on pfortuny’s (correct) interpretation “those events are only separated be 1.1std deviations, which is little” of the original post by Gelman (the difference between a significant result and a non-significant result may not be significant = a city which is far from Jacksonville and a city which is not far from Jacksonville may not be far from each other).
Let's assume you've already decided in advance what "far" means.
Without moving either city from its current location, the same experiment can give you "very far" and "very close" in identical replications.
