Michael Wilmot and his team (Nick Haslam, Jingyuan (Sarah) Tian & Deniz S. Ones) re-examined archival data from previous surveys of nearly 4,500 people across the US and UK, whom had participated in old Type A surveys years ago. They were unable to achieve similar results that suggested “Type A” is a naturally occurring personality type, and found that personality is better understood as sliding scales of specific traits rather than categories.
