Selecting to keep people away from any potential danger above the level of 0 seems like a fairly good design. You're not paralyzed, merely cautioned, and then your offspring will inherit whatever level of that fear or worry from you based on if and how you've learned to trust what dogs are safe. If a dog attacks you at 3 years old then your environment isn't all that safe - and it makes sense then you may not have guardians who can adequately protect you or keep you in a safe environment. There are tools however to lessen and/or remove such negative conditioning, and it makes sense that that would require actual directed/focused work than just randomly being unafraid of something dangerous - and perhaps better to heal trauma closer to the trauma so neural pathways don't evolve/expand into everything for years or decades.

E.g., if you are hurt by a person, and you become afraid of that person (or people with those characteristics), that is helpful. If you are hurt by a person, and you become afraid of people... that is not so good. If that happens, how to treat?

This article suggests an approach that might allow emotional memories to be "balanced" through some kind of neuromodulation. Promising.

There are multiple layers to the solution which all relates to the pressure on your nervous system, what baseline stress/pressure you have - which ties into stress/factors including inflammation.

Many people self-medicate with inflammation without realizing it, inflammation having a depressant effect - and many foods causing inflammation, meaning our connection to our bodies and feelings are suppressed some to heavily depending on inflammation (and how long we've used food-as-a-coping-mechanism/medication).

Cleaning up diet as much as possible, reducing inflammation as much as possible - includes working towards a healthy weight and water fasting + intermittent fasting seem to be the ideal way, along with allowing the brain to have fluidity again with psychotropic plant medicines seems to be one ideal as well: MDMA for post-traumatic stress therapy, Psilocybin mushrooms (magic mushrooms), and Ayahuasca ceremonies are also powerful tools - that research is beginning to show.

There are also diagnostics possible for our sensory (e.g. through auditory channel) to check for imbalances and sensory processing blocks, which allows for accurately predicting a set of behaviours depending based on the diagnostic - and then sound therapies that exist to help 'unlock' those blocked development processes.

Then there are different levels of modalities of getting the nervous system and energy flowing again, from being more stagnant to completely stagnant - some more 'brute force' methods like acupuncture - Traditional Chinese Medicine methods - to the more subtle energy movement of say Reiki or osteopathy; and without getting into a debate - or arguing that placebo is a powerful benefit on its own - a further level of subtlety - if you believe in them or are sensitive enough and therefore potentially fragile enough to experience benefit from them: homeopathic remedies.

Do you have any references on the sound therapies? Sounds interesting.

Its said often that our ability to learn, but not unlearn, encapsulates most human progress as well as defeat, both at a personal and global level.

Exposure therapy is pretty effective and works by introducing new information, so it can't be too defective. A cat scratched me when I was a kid and I was afraid of cats for a few years, but I met some friendly ones and overcame my fear. I'm guessing the updating is harder for some, especially risk-adverse types (those more sensitive to negative stimuli and less sensitive to reward).
