Even though there are many reliable and valid personality measures available to clinicians, many clinicians still use methods like the Rorschach test and the Myers-Briggs Typology Indicator. This is because clinicians are vulnerable to errors like illusory correlations and confirmation bias. These errors can cause them to rely on methods that are familiar or comfortable to them, even if those methods are not as reliable or valid as others. Additionally, some clinicians may not receive training on how to evaluate the efficacy of tests, leading them to rely on methods that they believe have worked in the past.
