Directly Measuring the General Factor of Personality: Preliminary Evidence for a Personal Growth Quotient
A few years ago, I decided to test whether a person's ability to grow from feedback might have anything to do with their Big Five Personality traits. I created a psychometric scale, and paid ~1600 people to take it, along with two other Big Five measures. Along the way, I used the data to refine the scale via a few rounds of Factor Analysis, assess its reliability.
Not only is the scale decently reliable, it correlates with every factor of personality, providing support for my initial hypothesis.
You can see a summary of the results below: The Y-axis shows individuals' "Big Five Blend" or the average of their Big Five Traits. The X axis shows their score on the Openness to Personal Growth scale.
