I’m increasingly convinced that worldviews / mental models are not simply modeling devices, but information rejection tools. Borrowing from Clay Shirkey's "It's not information overload, it's filter failure", the world is a surprisingly information-rich space, and humans (or any other information-processing system, biological or otherwise) simply aren't equipped to deal with more than a minuscule fraction of it.
We aim for a useful fraction. It paints an incomplete, but useful picture.
Even a bad model has utility if it rejects information cheaply: without conscious effort, without physical effort, and without lingering concerns or apprehensions. It's a no-FOMO mechanism.
Usually, what happens is that we apply our bad models to a given scenario, act, process the new resulting scenario, and notice that that is obviously not favourable, and take appropriate actions to correct the new circumstance. Net loss: one round of interaction. Net gain: not succumbing to analysis paralysis or having to hunt for a new and improved worldview (especially: a new concensus worldview shared with numerous others, creating a large coordination problem).
Sometimes that doesn't work out and people (or companies, or governments, or cultures) get stuck in a nonproductive rut, often characterised by "doing the one thing we know how to do, only harder".
The big problem comes when there's a recognition that a former large-scale world model no longer applies. I'm leaning strongly to the notion that this is behind many psychological conditions: Grief, denial, meloncholia, depression, PTSD. Possibly burnout and ADHD.[1]
Classic grief is triggered by the loss of a loved one, or in the "five stages of grief" study, news of the subject's own impending mortality (a fatal disease prognosis). That is, an invalidation of a previously-defining mental model. This triggers denial, anger, bargaining, depression, and eventually, for some, acceptance of a new world view.
It's a pattern once recognised that one sees repeated across numerous scenarios, and scales, from individuals to groups to entire countries --- almost any disaster, epidemics, global catastrophic risks, wartime attacks, business failures, relationship breakups, and on. The phenomenon intersects with the problem-solving success (or failure) chain.
What's curious to me is what the threshold for grief or denial is. There are some surprises which don't elicit this response: almost all humour is based on the principle of surprise, and horror films and thrill rides are based on the premise of surprise or extreme experience, but rarely result in a traumatic response. We go through our daily lives experiencing small and medium-sized suprises and disappointments all the time. The grief/denial response seems to be triggered only above a magnitude or repetition threshold, though that can differ markedly between individuals.
Notes:
- I'm not claiming that all PTSD, burnout, and ADHD are grief responses, but rather that there are at least strong similarities. Early psychologists linked grief and melancholia (itself then considered a much stronger longing, to the point of mental illness). The mechanisms for overload might be internal --- chemical, physical, illness, injury, or genetic in origin --- or external. But there's a common thread that seems to run through these conditions, ultimately an inability to cope with a level of change.
