The Big-5 aka OCEAN model (openness / conscientiousness / extroversion / agreeability / neuroticism) constitutes the most scientifically accepted framework for measuring personality. It is confirmed by decades of work and massive amounts of large-n survey research.
One of the major giveaways that the Diversity VP at Google is incompetent came when she criticized the author for attacking women simply because he used the terms "conscientiousness" and "agreeability" and "neuroticism". You are not doing much better by insinuating that science can only be correct when it supports your ideological position.
