There are a lot of misconceptions about reference checking and questions as to whether third-person insights can really provide value. In this article, we debunk five of the most common myths about reference checking!
1. Reference Checks Have Low Validity
The rumour that reference checks have low validity probably comes from scientific studies published in the 20th century. In a frequently cited article, Schmidt and Hunter (1998) summarised scientific findings on how well different personnel selection procedures predict work performance. Compared to other personnel selection procedures, Schmidt and Hunter (1998) found that reference checks have relatively low validity. However, as Zimmerman et al. (2010) pointed out, the studies conducted during the 20th century mainly used unstructured reference checks.
Few people seem to know that during the 21st century, new studies have instead investigated the validity of structured reference checks. These new studies (e.g., Hedricks et al., 2013; Taylor et al., 2004; Zimmerman et al., 2010) have shown strong correlations between reference checks and work performance. Thus, the available research suggests that reference checking can be a valid predictor of work performance if it is conducted in a structured way.

2. Reference Checking is Only a Compliance Activity
In the United States, if an employer fails to do a proper reference check of a potential employee, the employer may be guilty of negligent hiring if the new employee causes harm to others (Gusdorf, 2008; Igwebuike & Isaac, 2014).
Recently, the largest verdict in American history in negligent hiring was delivered, ordering an employer to pay more than $1 billion for the murder of an elderly woman who was killed by a service technician in her home (Ars Technica, 2022; NBC News, 2022; XpertHR, 2022). According to the plaintiff's attorneys, a routine reference check would have revealed that the service technician had a work history of harassment and falsifying documents. Had a proper reference check been conducted, the attorneys' said it would have disqualified him from employment. Thus, reference checking is not just a compliance activity. It is a valid predictor of work performance and can also reduce the risk of hiring someone who harms others.
3. Reference Checks Are Useless Because the References Are Nominated by the Job Applicants Themselves
Job applicants who select their references are apt to choose raters who are likely to give the applicants’ the highest scores. Therefore, there is a question as to whether there will be enough variance in applicants’ scores received from applicant-selected observers to allow for meaningful prediction of performance criteria. To answer this question, Zimmerman et al. (2010) created a structured reference check which included measures of the personality constructs Conscientiousness and Emotional Stability. The results showed that although the job applicants chose their raters, there was still enough variance to allow for the structured reference check to be a valid predictor of work performance.
Meta-analyses have shown that observer ratings of personality outperform self-reported personality in predicting work performance (Connelly & Ones, 2010; Oh et al., 2011). Thus, the insights that can be gained from people who have observed an individual may be more useful than the information provided by the individual.
It is also worth mentioning that reference checking is the only aspect of a recruitment process where the information does not come directly from the job applicants. If the references are apt to say positive things about the job applicants, consider how inclined the job applicants are to present themselves positively (e.g., during the job interview). In their study, Weiss and Feldman (2006) found that 81% of job applicants lied at least once during a job interview. Still, job interviews continue to be one of the most frequently used methods to assess job applicants (Macan, 2009).
4. If You Need to Do Reference Checks, You Didn't Do a Good Enough Job Earlier in the Process
Since reference checking is the only aspect of a personnel selection procedure where someone other than the job applicants themselves provide information about their behaviour, reference checks can add information that helps recruiters paint a better picture of the applicants. For example, during a job interview, few applicants would say that they are usually late for work. Such information may only be gathered by contacting former employers and colleagues.
5. A Job Applicant's Behaviour in a Previous Organisation is Irrelevant Because the Organisational Contexts Differ
Meta-analyses have shown that measures of personality traits can be used to predict work performance (Ones et al., 2007) and other outcomes that organisations care about, including organisational commitment (Choi et al., 2015) and employee engagement (Young et al., 2018). A defining feature of personality traits is that they are stable (Boyd & Pennebaker, 2017; Briley & Tucker-Drob, 2014).
Personality differences between individuals contribute to the explanation of why one individual behaves differently from another individual in a comparable situation (Shweder, 1975). Thus, if you observe a group of people, their personalities will influence them to behave differently from each other, regardless of the organisational context. Because personality traits are stable, observer ratings of applicants’ personalities in previous organisations can be used to predict behaviours in other organisations.
