The analysis you quote smells of vapid pop psychology. What empirical evidence exists for supposing that the result is reliably objective, let alone relevant?
It should smell more like philosophy class 101 to you. "Either X or not X. If X, either Y or not Y."
I can point you to https://en.wikipedia.org/wiki/Truth_table if you need empirical evidence that people sometimes actually think claims through sometimes for a few minutes. Otherwise I'm not sure what you're asking for.
