I don&#x27;t see how this measures analytical capabilities.<p>For example, people with mild ADHD will probably fair poorly on your tests. Now, if you are hiring for something that requires profound attention to detail (dispensing medicines in a hospital), keep on. If you are trying to measure analytical abilities, you should try measuring that, not some proxy that has little to do with analytical abilities.<p>(and the reverse also applies - I know people with great attention to detail but that I wouldn&#x27;t rate particularly highly on analytical skills).
