I was 2/3 the way through a Masters degree program when I made a life decision to abandon education for other pursuits. While I agree that advanced college degrees are often attributed to the more intelligent of society, that is not the only qualifier of personal intelligence. Much like a Masters degree holder would more than likely not be able to install plumbing or electrical in a new construction home, a plumber or electrician more than likely would not be able to perform surgery.......not because of a lack of intelligence but rather a lack of proper training for training is more the precursor of professional outcome than intelligence.
I’d agree with most here. Mechanical and industrial services definitely require trained skills . But not the extended education and intelligence of say a doctor or engineer, maybe even a lawyer or accountant for example.
That doesn’t mean a skilled mechanical person doesn’t have some level of intelligence and in many cases more common sense.
But they haven’t dedicated themselves to the extended education needed . And that doesn’t mean they wouldn’t have the ability to educate themselves if they dedicated the time and energy to gain such knowledge .
Ultimately intelligence is defined by knowledge which is normally gained thru education and extensive training. However there are some exceptions with people who have gifts and god given abilities who simply don’t utilize or develop them.
Ive known a few who didn’t fulfill their education and didn’t meet their potential . Our society is full of under achieving slackers who have basic intelligence but didn’t further themselves with knowledge and training.
