INTJ: I believe A is true because of B.
INFJ: There is no evidence that B has influenced A in this case.
That isn't saying the he thinks the INTJ is wrong. The INFJ understand very well that A could be true because of B. He is only asserting that it isn't an appropriate conclusion to make with the available evidence. The INTJ never provides any evidence to support his conclusion, only insinuations of why B could influence A.
But your response sounds exactly like what meta was talking about. I'm starting to seriously wonder if you might be an INTJ.
