# Testosterone and Leadership

© Straits Times - opinion sought from PsyAsia's director, Dr Graham Tyler

Note: In the [article](https://drive.google.com/open?id=19KV_h35dhluOuf1cpKeJOaUl_nQD6JEs), there is a mention that aptitude tests can predict between 9-36% of performance. This is incorrect. The journalist asked about personality tests and was told that traditional personality tests can predict about 9-36% of performance. Aptitude tests are able to predict more than this and more modern personality assessments such as Identity® or the Quest Profiler® do an even better job than traditional personality tests!
