Jackson MacKenzie's Whole Again and the Emotionality Facet (O3)
Jackson MacKenzie built a huge online community for survivors of toxic relationships, and Whole Again is his book about the strangest part of recovery: the emotional numbness that sets in after abuse, and the slow work of feeling again. His own turning point was his heart reopening. On his site he writes, "There is a way back to this bliss, and as my heart began to open this year, I felt compelled to share what I've learned (and where I've stumbled) in a new book." How open you are to feeling your own emotions is, in the Big Five, one facet.
Re-opening to your feelings is the Emotionality facet
That facet is Emotionality (O3), under Openness, how open you are to noticing and feeling your own inner emotions. A high scorer feels their feelings vividly and lets them in; a low scorer keeps them at a distance. MacKenzie's insight is that trauma can shut O3 down as a defense, numbing a person so they stop feeling the pain, and eventually stop feeling much of anything. Whole Again is about coaxing that access back, letting sensation and emotion return where they were sealed off. This post is about the trait rather than a diagnosis, and it is a companion to treatment, not a replacement for it.
What makes his framing useful is that it treats the numbness as protection rather than damage. A part of the self went quiet to survive something unbearable, and healing is a matter of making it safe enough to reopen on its own, rather than forcing it. That reframe pairs with a return of steadier Vulnerability (N6), since feelings can only come back when the nervous system trusts they will not overwhelm it. MacKenzie's core promise is that the capacity to feel was never destroyed, only disconnected, and that reconnection is the whole of getting well.
For a reader placing themselves, your O3 is a fair read on how close you live to your feelings and how easily you can let them in. High on it and Whole Again names a numbness you may have felt after a hard relationship and a way back from it. Low on it and the book is an invitation to consider that a cooler distance from your feelings might be protection you no longer need. Where you sit on Emotionality tells you how open you are to your own inner world, and we take the facet apart in Emotionality (O3).
