Is it plausible to create a world in which the people who live inside it developed technologies like the ones we had in WW2, but after their progress came to a halt they forgot their knowledge. Meaning that they still have their weapons, tools, etc. from that time but don't know how they work, scientifically? Could it be from a nuclear apocalypse?



Example: Knowing how to drive a car but not knowing how they work.

    'Don't know how they work' means they won't last long. If nobody can repair the car, then it soon won't be drivable. It also means that nobody can build new cars. So they won't have their fancy weapons or tools after all, but instead the weapons and tools that they do understand. Nuclear apocalypses kill lots of people and poison large swathes of land, but don't really make people stupider.

It seems that what you want is something that retards human problem-solving skills. This can be done with disease or toxins.




Exposure to certain types of disease or toxins. Diseases like whooping cough, measles, or meningitis can cause intellectual disability if medical care is delayed or inadequate. Exposure to poisons like lead or mercury may also affect mental ability. (Source)




Difficulties with the idea



  • There is no such thing as something that can retard problem-solving skills for one subject but not another. What gives us the ability creatively use a tool (e.g., how to drive a car somewhere we haven't been before), gives us the ability to understand the tool.

Said another way: if you take away our ability to understand the technology behind a car (gears, friction, leverage, combustion, electricity, etc.) you also take away high-volume farming, large density water distribution, disease control, etc. The underlying technology used to maintain society at the population densities enjoyed during WWII would very quickly turn cities into death traps (starvation, sanitation, disease).



Said in yet another way: Losing the ability to design, repair, and maintain a car means losing the ability to understand why you'd use the car in the first place. You wouldn't solve the problem of getting from A to B by thinking, "I can use a car to do that!" You'd simply walk there, having never considered the car as a possible solution to the problem.



  • It takes time. Nothing can retard brain functions in a moment, or even in weeks. It may take months of lead exposure to begin affecting a child, but it would take years to begin affecting a trained adult. Why? Because cognition is very complex, involving memory, sensory processing, abstraction and association, etc. A great deal of adult behavior has transitioned from learning to do something to the habit of doing something. This is why people with forms of dementia can drive cars (they may have no idea where they ended up, but they successfully operated the vehicle). This is because the skill of driving has become so habitual that it doesn't require nearly as much thinking as it does when learning how to drive.


  • Radiation isn't selective. Radiation strong enough to destroy the brain's higher functions is destroying the rest of the brain with them, including its ability to manage autonomic functions like breathing and blood circulation.


But... plausible?



I believe forced mental retardation of a large population is plausible from the perspective of an engineered disease so long as you remember that such retardation will manifest in specific ways with very general results. Here's a few off the top of my head.



  • Poor memory recall.

  • Poor memory association.

  • Poor memory retention (very similar to recall, but not quite)

  • Poor abstraction (everything becomes very, very literal, necessary for mathematics and language)

  • Poor sensory processing

    I think that is entirely possible. It likely needs to be from some apocalypse that pretty much shuts down education. That doesn't have to be nuclear, it could also be global warming melting all the icecaps and making much of the world inhabitable, it could be a religious know-nothing apocalypse (religion takes over that rejects "science" as evil because it creates doubts about scripture, for example).



    You fictionally need to destroy the modern engineering college education, because that is how the next generation actually learns about creating machines, semiconductors, computers, etc. Up through about the Master's degrees. Then the PhDs go on to discover new principles, materials, etc to create NEW devices and machines.



    If you stop the education around the middle school level, you might have some that can fix simple cars and engines, but nobody would know how to fix modern computerized cars and engines.

            I think that is entirely possible. It likely needs to be from some apocalypse that pretty much shuts down education. That doesn't have to be nuclear, it could also be global warming melting all the icecaps and making much of the world inhabitable, it could be a religious know-nothing apocalypse (religion takes over that rejects "science" as evil because it creates doubts about scripture, for example).



            You fictionally need to destroy the modern engineering college education, because that is how the next generation actually learns about creating machines, semiconductors, computers, etc. Up through about the Master's degrees. Then the PhDs go on to discover new principles, materials, etc to create NEW devices and machines.



            If you stop the education around the middle school level, you might have some that can fix simple cars and engines, but nobody would know how to fix modern computerized cars and engines.
