The author seems to be projecting their own above average intelligence onto other people. He’s imaging their inner world to be somewhat like his when it’s anything but.
> but they’re intelligent when it comes to their own lives and the areas they work and spend time in. We should expect the average person to struggle with factual questions about abstract ideas and far-off events, but not so much about what’s right in front of them day to day.
This is cosmically untrue. My cleaners can’t work my vacuum. I’ve spent a year constantly re-explaining it. They can’t put the oven racks back the way they found them, just force them in the wrong way around every time. No number of reminders seems to help. My landscaper could not work out he had our landscape wiring crossed, spent days coming back replacing bulbs, digging up wires and replacing them, randomly rewiring sections. 5 minutes with a multi-meter and I had it solved. I know a nurse who thinks deoxygenated blood is blue.
The average person tries to memorize a handful of things from someone smarter and then stays in their lane. That’s fine, I don’t think we should call them “stupid” but capable thinkers and problem solvers they are not.
The author seems to be pretending these people don't exist, and I think you made a good guess as to why.
