My wife became much more assertive and disagreeable after we had a special needs child in the NICU for nine months and the constant pressure from doctors to get unnecessary procedures like a tracheostomy. They also said we didn’t have to resuscitate her if we didn’t want to. Constant battles and pressure and my wife can be a stone cold bitch now when she needs to be, where she used to just say “okay”.

Our daughter is seven now, she does use a wheelchair, but is normal intelligence and just went in her cute little electric car she got for Christmas with her big sister to a friend’s house down the street. I’m so proud of her, and my wife.

So sometimes these traumatic events improve your personality in the sense that they give you a more realistic way of how the world actually works, and how to achieve your goals (especially when those goals are dearly held, like “I want my child to survive and have the best quality of life possible).

Also, with COVID I’d imagine a lot of the neuroticism going up or down depended on where you were and your philosophy. For me, and a lot of people leaning conservative, living in the Midwest, I think it is less neurotic, perhaps to our detriment. Totally disregarding health warnings, and being insubordinately against precautions rather than becoming more neurotic. Many of these people got covid. One died. Most were fine. There is likely a “correct” amount of neuroticism, although that obviously changes depending on your circumstances.

Extremely high neuroticism would help someone who was Jewish in 1930s Europe decide to get themselves and their family out of there at any cost, but extremely high neuroticism might not be great during the Pax Americana of the last 60 years.
