An explanation that makes a discussed situation less plain by
complicating what's apparent.
Also describes the process of looking a gift horse in the mouth and naming each tooth, after you

Often used by doctors, lawyers, and sociologically sane scientists
for profit. (The mad ones do it just for the kicks).
When "It works, just because," is no longer an acceptable explanation due to decreased intimidation and a refusal to settle.
