Intelligence and IQ have nothing to do with education. It wouldnt have anything to do with leadership because ones mental intelligence has nothing to do with that either. Nor does technology, it has no bearing on how a person is wired. People are not understanding and getting confused with another definition of "intelligence". Information gathered by say one of the alphabet companies.
Intelligence - how the person uses information, logic and application of reason, the ability to learn skills and obtain knowledge and process it.
Education - the content, knowledge or information that one can use and apply.
Neither are really related.
The lowering of the IQ, just a guess off the top of my head... inbreeding, legalizing weed, substance abuse, big pharma, the American diet, all these people on prescription drugs and other drugs breeding. Idiots breed more because they are more impulsive and poor planners. And free healthcare prolongs their lives, idiots used to not live so long, now they live longer because of modern day medicine and healthcare. So naturally there will be more idiots and why you see the average dropping.
The highest IQ people vote Democrat. Let that sink in.
A statement like that I would assume is created to sway the low IQ people to follow suit. IF there is any merit to it, its likely because more intelligent people (higher IQ) are more busy (they have good jobs, hobbies, families) and dont saturate themselves with the news which we all know is bought and paid for propaganda. So they skim the headlines and are just misinformed and unaware, the way most the country was about politics pre-internet. Today, statistics and the outcome of all surveys, polls, are greatly influenced and determined by who funds them. Also there is a flood of things going on, purposely flooded, distractions, mass information, more than than most want to take in.
