[Blade Runner] If replicants have major physiological differences from humans (e.g. the ability to lift 400 pounds of cargo all day every day), why is something as nuanced as a voight-kampf needed to identify one?

Its unconstitutional to forcibly perform any inspections which would easily identify most replicants (MRI, open surgery, dna scan) without probable cause.

The Voight-Kampf test relies on exterior observation and a simple interrogation which doesn't even require the person to answer honestly.  That's why its so advantageous in identifying replicants.  Its completely legal and non invasive.
