Does an intelligence test lower the chances of getting a job?

After a literature review, the researchers of the Knowledge Platform for Inclusive Cohabitation (KIS) conclude that yes.
In fact, they conclude that a quarter of the residents of the Netherlands have less chance of getting a job by using an intelligence test.
An interesting but also quick conclusion that requires some nuance, says Manon Hassink, R&D manager at Ixly. “Assessments are about more than just IQ. Although an intelligence test is an important tool, we recommend that selection decisions are never based solely on it. It's just one part of a broader assessment, which includes, for example, personality, motives and the results of a well-structured interview.”

Objective tests: a level playing field
Hassink emphasizes that objective tests actually contribute to a level playing field, something that is often not achieved with informal conversations alone due to the influence of conscious and unconscious bias. This bias also plays a role during the CV selection. “A well-designed assessment shows what you can do and who you are, without factors such as origin, age, or gender reducing or increasing job opportunities.”

The science behind assessments
According to Hassink, the scientific basis of assessments is crucial. “The extent to which research is conducted into cultural bias and the steps taken to minimize it determine the quality and value of an assessment.” In addition, scientific research also shows that taking an intelligence test has a high predictive value for future work success.

Increasing knowledge in HR and recruitment
An interaction is necessary, says Hassink. “On the one hand, assessment providers can be more transparent about how their tests are developed. On the other hand, HR and recruitment professionals should be better informed about the psychological models, the scientific basis of assessments, and how to use them optimally. This is the only way we can create better and fairer selection processes.”

Inclusion through customization
At Ixly, it is possible to opt for intelligence tests that take into account specific needs, for example for people with dyslexia or ADHD. This customization contributes to more inclusive and fairer selection procedures.
