gapology
n.— «As a student of gapology, I was both thrilled and puzzled by the sudden appearance of the gender gap.…As a gapologist, I enjoyed seeing the upstart science of fenestrology embarrassed. Still, things were distressingly quiet on the gap front until suddenly the gender gap appeared.» —“The Gap’s Progress” by Russell Baker New York Times June 18, 1983.
