"Firefighting doesn't require the depth of knowledge that medicine does, but it requires practical knowledge, quick thinking, a cool head along with lots of courage."
Rubbish, it requires considerable cognitive skills. And, the more predictive tests are for cognitive skills the greater disparate impact they have.
"The major legal dilemma in selection is that the best overall predictors of job performance, namely, cognitive tests, have the most disparate impact on racial-ethnic minorities. Their considerable disparate impact is not due to any imperfections in the tests. Rather, it is due to the tests' measuring essential skills and abilities that happen not to be distributed equally among groups (Schmidt, 1988). Those differences currently are large enough to cause a major problem. U.S. Department of Education literacy surveys show, for example, that black college graduates, on the average, exhibit the cognitive skill levels of white high school graduates without any college (Kirsch, Jungeblut, & Kolstad, 1993, p. 127)."
