The rise of popular personality tests
Free, playful personality tests have become popular. They are often more accessible and user-friendly than traditional tests, with a modern design and technology that put the user experience first.
However, a focus on design and entertainment can come at the expense of the scientific foundation. That affects the reliability of the results and the trust you can place in them.
What do reliability and validity mean?
Reliability and validity are two essential pillars for any psychological test, but they are often overlooked when it comes to modern, flashy variants. What do these terms actually mean, and why are they so important?
Reliability means that a test produces consistent results. Suppose you take a personality test today and take the same test again a week later. If the test is reliable, the results should be almost identical since your personality has not fundamentally changed during that time.
Validity goes a step further. It means that the test measures what it claims to measure. For instance, a personality test should accurately map out someone’s personality, not another random aspect of their behaviour. Without validity, the test is useless as the results do not accurately reflect what you are trying to measure.
Some of the newer, trendy test formats offer little or no evidence of reliability and validity. Check whether the provider can show how the test was developed and studied.
Lack of privacy and mandatory surveillance technology
As more modern personality tests enter the market, new concerns about privacy also arise. Many of these tests ask users to grant access to personal data, sometimes without the user fully realising what is being shared. A worrying trend is that some of these tests require surveillance technology, such as activating a webcam, to ensure that the test is taken honestly.
Such measures raise questions about ethics, necessity and privacy. A well-designed test does not have to depend on external surveillance. With any self-report test, faking can never be ruled out entirely, so discuss results in a conversation rather than treating them as a verdict.
How we approach tests
At Profiles International we offer assessments that are tested for reliability and validated regularly. The product pages describe the reliability figures, for example for Profile XT (PXT). The assessments are designed to help organisations make informed decisions about recruitment, talent development and team dynamics.
Respect for privacy
You do not need to switch on a webcam for our assessments: for Profile XT (PXT) this is explicitly not required. You can read how we handle personal data in our privacy statement and in the article on privacy and security.
Experience and support
We support organisations that use our tests, from help interpreting the results to guidance on introducing them within your organisation.
Conclusion: quality over quantity
In today’s market, there are many options available when it comes to personality tests. It can be tempting to choose a test that looks modern and feels user-friendly, especially when it is presented with exciting technologies and a dynamic interface. But it is important to look beyond the surface.
Reliability, validity, and privacy are not terms to be taken lightly. They form the core of any test that truly provides value to both individuals and organisations. We believe that the quality of the test outweighs its visual aspect and that the value of a test lies in the reliability and usability of the results it delivers.
