Psychometrics can be key in understanding ourselves in general. However, they become particularly illuminating when we seek to understand toxic dynamics with narcissists. I was delighted to interview Dr Stewart Desson, CEO and Founder of Lumina Learning, the psychometrics tool I use with my clients. A few features I particularly like with Lumina are: - a breakdown into 8 aspects of personality - each divided in 24 qualities - each divided into three "personas": when we are relaxed, how ever are everyday, and when we are stressed - aspects and qualities are NOT mutually exclusive: we can score high both on introversion AND extraversion, or on logic AND empathy. I hope you enjoy this interview - I found Stewart fascinating. To learn more about Lumina Learning and the free Splash app (low resolution portrait), visit: https://luminalearning.com
