I think one way of dealing with the uncertainty of whom you can trust is to 'live in both worlds' - at least probabilistically. THis is nicely illustrated in this Dath Ilan fiction: https://www.glowfic.com/board_sections/703
When I realized that most news did not influence me, i.e., change my behavior or let me update my world model, I stopped reading it.

It is not a quote but a paraphrasing of what the OP might agree on about AI security.
When I realized this it helped me empathize much better with people who seem to know less - they make do with what they got!
I realize this doesn't answer your problem. I'm not sure there is a full answer but I think some progress can be made on understanding the mechanism you have outlined. See that it works, understand why it works, and when it seems to break down.
There are always some people who will troll you or give some fun answer - Lizardmen const. Though they will be able to answer if prodded.
I have found a source of some more plausible mechanisms tied to common emotions here: Dares, costly signals, and psychopaths (which references The Psychopath Code, see raw text on Github). These sources are focused on psychopaths but give extremely well-suited descriptions of the following classes of emotions:
Hunger [...] Your digestion slows. Your vision and hearing gets sharper and you focus on distinguishing prey from threats. You feel the need to move, yet you are careful to stay invisible. You walk without haste, and keep your posture relaxed. Your breathing is regular, slow.
Euphoria [...] Your hearing switches off and your vision tunnels in on your target. Your breathing and heartbeat accelerate. Blood flows to your muscles, and glucose feeds into your blood. Your eyes widen, your mouth opens, and you bare your teeth.
Surprise [...] "startle response." You flinch away from the threat, and raise your arms in self-defense. You lift your eyebrows and open your eyes wide to see better. Your hearing gets sharp. You exhale hard to clear your lungs of carbon dioxide. Your heart accelerates and you breathe in deep to oxygenate your body for action.
Love - [...] We establish "closeness" by mutual physical contact. The kinds of contact depend on the relationship. The closer you are to another person the more you feel the emotion. Your eyebrows rise, your pupils widen, you smile and laugh and feel happy. You use open and dominant body language. You are more childlike: playful and uninhibited. You seek more contact. You need less sleep.
All of the descriptions are like this, and I think an excellent source when looking for mechanisms that facilitate the recognition of the more abstract patterns.
I fully second this approach. It is very close to what we do and has worked very well. The oldest of our four boys is now 18, they have three parents, two homes and probably a dozen contexts from parents, grand parents, friends to school that they are comfortable in.
I'm not sure which section I like better but I definitely like that there are these two. They complement.
I liked your "Making sure that the balanced life is prioritized." I'm also FindingTheMiddleWay.
I like the flow of the post though it didn't tell me much now - but that's more because I'm an old magician. It may be good for apprentices.
There could be more about a sparkling way of being. I only found clothing-for-men which goes a bit in this direction.
