Why wouldn’t an employer want to know if a potential employee is a criminal? Who’s to say this information is irrelevant?
An IQ test is an excellent proxy for likelihood to engage in criminal behavior. Higher IQ people are more likely to see the consequences of their actions and they are more likely to feel empathy for others (requires abstract thought) and to see the future more clearly. Unfortunately, employers cannot give IQ tests to potential employees.
The Atlantic: “Too many applicants, particularly people of color, are being denied jobs based on background checks that are irrelevant or even inaccurate.”
