The fundamental idea here is that some people learn how to learn, and others need to always be taught.
Learning "huh, when I hit this switch my wifi turns on or off" is pretty simple. Some people need to be told, and even then it's just a rote mechanical process - no thought as to why, how, or even that the switch is connected to anything. It's all magic.
I wanted to learn to lift even though I've never stepped foot in a gym. I did my research and bought the right books. I went into a gym and did exactly what I set out to do.
I need to replace my windshield wipers. I look up the information for it - it's right next to the new blades in Walmart. Dead simple. I bet a lot of people go to Pepboys for that.
It's as if the scientific method never existed, life is magic, and knowledge can only be gained by truly extraordinary humans.
