I'm an INFJ and thinking about going into the sub-field: Industrial and Organizational Psychology.
Here's a little bit from Society of Industrial and Organizational Psychology, Inc. Homepage Article
Industrial-organizational (I-O) psychology is the scientific study of the workplace. Rigor and methods of psychology are applied to issues of critical relevance to business, including talent management, coaching, assessment, selection, training, organizational development, performance, and work-life balance.
As a fellow INFJ, I wanted to know what you thought about this field and whether or not it appeals to the INFJ traits. Lookin' forward to hearing what you think!
