if you want to do it right, you learn from the experts
like the experts in biology who deny The Creator, and give you the facts as to how blind chance created everything.
like the experts in psychology (whose basic tenet is to rid oneself of shame and guilt),who understand the workings of the human soul (if they at least dont deny its existence) so much better than Talmidei Chochomin.
and the economic and political experts who again ascribe all their conclusions to chance and “historical principles” and deny there is a Boreh who controls and conducts the events of the world
yes certainly it is critical for a Rabbi to learn this “knowledge” in order deal with the problems of their congregants. the depths of the wisdom of the Torah just cannot compare.
and of course Poskim cannot consult with technologic experts. their minds are too dull to understand what they are saying unless the Poskim first exposed themselves to the tumah of the colleges beforehand.
