More like science as hysterical racism. The "crack baby" mark was created by a bunch of terrible studies in the 80s, and seized on as convenient by a lot of terrible people. This is simply the last of a large number of studies that have found no relationship, all of which occurred well after the time when the term was useful to those terrible people.

This is science correcting itself after power has ceased to care what position science takes on the existence of the crack baby.
