==Criticism== Audit studies have been criticized because the auditors may look different to employers, and this may result in the appearance of discrimination when employers were really just making decisions based on appearance.<ref>{{cite journal|last1=Neumark|first1=David|title=Detecting Discrimination in Audit and Correspondence Studies|journal=Journal of Human Resources|date=2012|volume=47|issue=4|pages=1128–1157|doi=10.3368/jhr.47.4.1128|hdl=10419/46132|s2cid=17645916 |url=https://econpapers.repec.org/RePEc:iza:izadps:dp5263 |hdl-access=free}}</ref> The other limitations of these studies, according to their critics, include that they are unable to audit jobs found through interactions with other people directly, only those found through newspapers.<ref name=jep>{{cite journal | jstor=2646964| title=Detecting Discrimination | author=Heckman, James J. | journal=The Journal of Economic Perspectives | date=Spring 1998 | volume=12 | issue=2| pages=101–116 | doi=10.1257/jep.12.2.101 |doi-access=free| citeseerx=10.1.1.371.4425 }}</ref> Additionally, others have noted the lack of standardization of signals (primarily names) to indicate race through correspondence (e.g., resumes and emails).<ref>{{cite journal|last1=Gaddis|first1=S.

Other criticisms concern the ethics of running such experiments. Specifically, it has been pointed out that audit studies do typically not obtain informed consent of participants. Simultaneously, they generate some though usually low costs to participants and rarely provide benefits. Because of this, the literature has developed multiple guidlines to judge the ethics of an audit study on discrimination specifically. This includes judging (1) the potential harm to participants, (2) against the benefits of having a reliable measure of discrimination, (3) and taking into account whether there are other, less harmful ways to measure discrimination in the same setting. Finally, (4) deception should not strongly violate the norms of the setting the experiment is conducted in.<ref>{{Cite book |last=Salganik |first=Matthew J. |title=Bit by bit: social research in the digital age |date=2019 |publisher=Princeton University Press |isbn=978-0-691-15864-8 |edition=First paperback printing |location=Princeton Oxford}}</ref>
