In a study by Booksh et al., the WMT performs better than clinical judgment in classifying students asked to simulate ADHD

Poor effort has a greater effect on Connors’ CPT than does ADHD.

Clinical judgment has high false positive rate, whereas WMT has a zero false positive rate. The Fifteen Item Test displays zero sensitivity (It is impossible to get worse sensitivity than that!).
