The Evidence on Pre-employment Credit Checks
Elizabeth Warren, a blogger who left Credit Slips for the lesser fame of the U.S. Senate, has introduced the Equal Employment for All Act, which would bar credit checks for most pre-employment screening. A few states already have taken steps in this direction, with varying levels of efficacy. Senator Warren's bill would institute a federal ban and has been widely reported elsewhere (see here (Slate Salon) and here (CBS) for useful overviews).
The growth in the use of pre-employment credit checks has been the subject of several Credit Slips posts. Katie Porter first noted the development in 2006 and in 2010 discussed Rep. Steve Cohen's bill which was the model for Senator Warren's proposed legislation. Debb Thorne commented about the lack of any evidence connecting credit reports with job performance. Debb's own research documents how "off label" uses of credit reporting undermine bankruptcy's fresh start when credit reports are used to determine things like how much people pay for insurance or whether they get a job.
Senator Warren's bill has attracted opposition from the expected places such as the Consumer Data Industry Association and the Society for Human Resources Management. The former has data to sell, and the latter has services to sell. Those motives do not necessarily make their positions illegitimate. We should keep in mind, however, that there is money to be made in convincing those who make hiring decisions that there are data and services that can unlock the hidden traits of job applicants.
Such claims play into a well-known psychological phenomenon known as the fundamental attribution error or the correspondence bias. As Gilbert & Malone put it:
People care less about what others do than about why they do it. Two equally rambunctious nephews may break two equally expensive crystal vases at Aunt Sofia's house, but the one who did so by accident gets the reprimand and the one who did so by design gets the thumbscrews. . . .
Attribution theories suggest that the psychological world is a mirror of the physical world and that the two are therefore penetrated by the same logic. Ordinary people seem to believe that others behave as they do because of the kinds of others they are and because of the kinds of situations in which their behaviors unfold . . . .
Attribution theory makes a distinction between situational and dispositional causes. A common mistake is to attribute an action entirely to a dispositional cause while ignoring possible situational causes. For example, when observing a driver running a red light, we often will jump to the conclusion the driver is reckless and ignore explanations such as a medical emergency.
The efficacy of pre-employment credit checks plays exactly into the fundamental attribution error. When we see someone with a bad credit report, we tend to attribute it to dispositional causes (poor financial decision making, financial recklessness, dishonesty) than situational causes (health problems, layoff, divorce). Moreover, we probably are especially prone to make the fundamental attribution error when it comes to financial problems. A dispositional cause allows us to tell ourselves the financial problems will not happen to us because we believe ourselves to lack the necessary disposition that will lead to the problems.
The fundamental attribution error, however, does not mean that dispositional causes are never partially or fully explanatory. Sometimes people run red lights because they are reckless, or sometimes bad credit results from a fundamentally dishonest nature. Usually, the most complete explanations for any social phenomenon are multicausal. The question raised by Senator Warren's bill, however, is not whether some people might have dispositions that correlate with financial irresponsibility but whether credit reports can screen for bad employees. The fundamental attribution error makes us want to believe they can do so, but there is almost no evidence to support that notion (although more research would be useful).
A paper in the International Journal of Selection and Assessment by Oppler, Lyons, Ricks & Opper has been cited by the opponents of Senator Warren's bill. That paper, however, does not look at the use of credit reports, but instead examines two questions used on an employment application at a large federal agency (maybe the Bureau of Prisons given the authors' institutional affiliations). The questions asked if the applicant (1) had filed bankruptcy in the past seven years or (2) was currently more than 180 days delinquent on a loan or financial obligation. The study then looked to see if answering "yes" to one of these questions was correlated with "counterproductive work behaviors," which for purposes of the study was defined to include failure to pay debts and misuse of credit cards. Thus, the study seems to find that persons who are more than 180 days delinquent on a loan or financial obligation are also more likely to fail pay debts or misuse a credit card. The paper has little relevance to the debate over pre-employment credit checks.
The rest of the research finds credit reports to be of no predictive value. A paper in the Journal of Applied Psychology by Berneth, Taylor, Walker & Whitman found no relationship between deviant employee behavior such as theft and credit score. The primary thrust of the paper was to examine the correlation between credit scores and the "big five" personality traits. The paper did find an association between credit scores and conscientiousness, but it also found a negative relationship between credit scores and agreeableness. The other personality traits were not correlated with credit scores. A different paper by Bryan and Palmer in the Psychologist Managers Journal found no correlation in a large financial services company between predictors extracted from credit reports and employee ratings or negative terminations.
What we do know is that pre-employment credit checks have a strong negative perception among the general public (see Kuhn & Nielsen). Over at Demos, Amy Traub has documented the negative consequences of pre-employment credit checks and their disparate impacts across racial lines. By making it more difficult for hard-working Americans to get back on their feet, pre-employment credit checks contribute to the perception that the game is rigged as well to the growing wealth inequality that plagues this country. It will be a difficult sell, however, as human nature makes us want to believe that credit reports must tell us something about the person involved. It is just another example of how we think we know what it isn't so.
