"Objective" truth is what you can derive from physical reality by logical arguments. The very opposite of "belief".
Social truth is what your social peer group wants you to believe.
"Effective" truth I've never heard about and your explanation merely describes a simplistic popular scientific method concept. Leading ideally to the objective truth I was talking about.
The internet describes "effective truth" (or "effectual truth," from the Italian la verità effetuale) as a philosophical concept introduced by Niccolò Machiavelli in his book "The Prince". It means judging people, leaders, and situations by their actual actions and real-world results rather than by their stated words, ideals, or moral promises.
