They apparently didn't normalize for socioeconomic status or IQ (or whatever the best indicator of overall intelligence that is currently known), which are two of the main variables that are usually accounted for in a race comparison study: especially as a prospective employer is more likely to hire upper-class people, and smarter people.
I have several issues with this "study".
Why is this in r/science? It was done with the direct intent of finding some evidence of discrimination. The methods with which they've gathered the data is suspect.
> These studies include both resume audits, in which fictionalized resumes with distinct racial names are submitted online or by mail (e.g., ref. 19), and in-person audits, in which racially dissimilar but otherwise matched pairs of trained testers apply for jobs (e.g., ref. 20).
> This produced 24 studies containing 30 estimates of discrimination against African Americans and Latinos since 1989, together representing 54,318 applications submitted for 25,517 positions. Finally, we performed a random-effects meta-regression to identify trends over time.
So they only targeted "ethnic" sounding names and the data was gathered from studies **since** 1989. If the data has been collected over a 30 year period and was filtered by names rather than a persons actual race, the "evidence" can't be used to say, "Now in 2017, whites receive 36% more callbacks than blacks."
That finding is absolutely not what they uncovered or could logically conclude.
Clearly this study was done in order to provide "evidence" of a false narrative that gives credence to ethnic and gender studies "scientists" that have nothing better to do with their time than claim victimhood and possible justify their tragic mistake of choosing a non-STEM field to pursue as a career.
So how do they know that it is purely from discrimination as to why certain groups got more callbacks? Seeing as how that's the only thing the measured from the study it seems like there could be other causes than discrimination, or even a combination of discrimination and others. Seems like a big assumption to just say that it is from discrimination without conducting further studies.
Wow. Considering the stance of pop culture and the media on racial issues today, you'd think we live in a post-racism world where all the remaining conflicts are about petty aspects of a white privilege or LBGT issues. Bit ironic that discrimination is functionally at the same level as the Reagan years.
