We know this, though, in aggregate, because sociologists have consistently demonstrated this with these experiments they build, where they send a bunch of applications to jobs out, equally qualified but some have white-sounding names and some have black-sounding names, and it's always disappointing, the results -- always.
Det här vet vi dock, eftersom sociologer konsekvent visat det genom olika expriment, där de skickar jobbansökningar, alla lika kvalificerade men några har "vita" namn och några har "svarta" namn, och resultaten är alltid en besvikelse - alltid.
