Why Training Matters

Critiques and Ethical Considerations

First off, the big question mark—validity. With skeptics raising their eyebrows, saying that IQ tests don't capture the full spectrum of human intelligence, it's hard to know if it's a useful tool. There are doubts about whether IQ tests can really predict success in the real world since the tests don't account for motivation, social skills, and practical knowledge, which are crucial for making it big in many professions.

Ethical Tightrope

The question that comes up in regards to utilizing IQ tests is whether or not they promote bias, especially when it comes to minority groups and folks from different socioeconomic backgrounds. Do IQ tests favor certain demographics? Do they leave others at a disadvantage? It's like trying to run a race when the starting line isn't level.

With so many red flags, is it ethical using IQ tests for employment and education? Perhaps you have a candidate who is perfectly qualified for the job, but they don't test well.​

Choosing the Right Test

When using an IQ test as part of the candidate assessment process for a job interview, it's essential to consider several factors to determine the most suitable test. Here are some considerations to help you choose the right IQ test for job interviews:

Relevance to the Job Role

The IQ test should assess cognitive abilities that are directly relevant to the job. For example, if the position requires strong problem-solving and analytical skills, an IQ test that emphasizes these abilities may be appropriate.

Fairness and Cultural Sensitivity

Ensure that the IQ test you choose does not have significant cultural or language biases. It should provide an equitable assessment for candidates from diverse backgrounds.


Consider whether the test can be administered efficiently in the context of a job interview. Some tests may be too time-consuming or complex for this purpose.

Validity and Reliability

Choose a well-established IQ test with documented validity and reliability. This ensures that the test measures what it claims to measure consistently.

Legal and Ethical Considerations

Be aware of legal and ethical guidelines regarding the use of IQ tests in employment settings, as some jurisdictions may have specific regulations or restrictions.


Ensure that the test is accessible to all candidates, including those with disabilities. Some IQ tests may have accommodations available for individuals with specific needs.

Scoring and Interpretation

Consider whether you or your organization have the expertise to interpret the results of the IQ test accurately. Some tests may require specialized training for interpretation.

Consultation with Experts

If you have access to industrial-organizational psychologists or experts in employee assessment, seek their guidance in selecting an appropriate IQ test for your specific job roles.

Navigating the Future of Candidate Assessment

Journeying through the world of candidate assessment has made one thing clear: IQ testing, like any tool, comes with its own set of strengths and weaknesses. It can help uncover hidden talents and gain valuable insights into candidates. It can also improve interviewing skills. But it also raises important questions. Are IQ tests valid, fair, and ethical?

IQ testing isn't the hero or the villain---it's a complex character that can play a pivotal role in candidate assessment. By understanding its potential as well as its limitations, we empower ourselves to make more informed decisions. We contribute to a hiring process that's fair and effective.
