Before I'd started my fade, I'd realized that...
a) ...one of the first major blunders the old WT theologians (and I use that term very loosely) made was making assumptions based on previously held bias, whilst expecting forthcoming evidence to corroborate said assumptions, and...
b) ...ignoring or dismissing any subsequent conflicting evidence because they'd already allowed their theological narrative structure to become too dependent on said assumptions.
This phenomenon held true with everything from historical chronology, to predictions of current events, to evolutionary science.
