Bessel van der Kolk's Body Keeps the Score and the Big Five

Bessel van der Kolk's central claim is that trauma is not just a bad memory, it is a change the body carries. In a published interview he explains why insight alone often fails: "Talking about it doesn't put it behind you because it doesn't go deep enough into the survival brain."

Trauma in the Big Five

Trauma is not a personality trait, and this is the important part: it can push trait scores around. The place it lands on the Big Five is Neuroticism, and two facets in particular. Vulnerability (N6) is how easily stress overwhelms your ability to cope, and Anxiety (N1) is how readily the threat system fires. Van der Kolk's survival brain is, in trait language, an N6 and N1 that learned to stay switched on.

Seeing it this way matters because it separates the wound from the person. A high N6 that grew out of trauma is not a flaw in character, it is a nervous system doing what it was trained to do, and his whole point is that it can be retrained through the body rather than argued with. His measure of recovery is social: "Being able to feel safe with other people is probably the single most important aspect of mental health." A facet score gives you a way to watch that change instead of guessing at it.

If your Vulnerability and Anxiety run high and you cannot find a temperament reason, his book is a good place to look for the other one. We read the Vulnerability side on its own in our N6 breakdown of the same book.
