Luke 10 v 21  In that very hour he became overjoyed in the holy spirit and said: “I publicly praise you, Father, Lord of heaven and earth, because you have carefully hidden these things from wise and intellectual ones and have revealed them to young children. Yes, O Father, because this is the way you approved.
This seems to show that 'higher education' was not needed to learn, understand and teach, the truth from God, at that time. 
It seems to be a well know thing within the JW Org and by people outside of same, that JW's are 'told' not to aim for higher education. I say told, although some will say strongly advised, with a possible caution of being disfellowshipped. 
Now I've noticed on here recently that deep conversation about many things has been and is taking place. Politics earthwide. religious beliefs earthwide and the latest thing seems to be Evolution (from a very deep standpoint ). ( These things were never taught to me at school. )
I left school at 15 years old, as soon as I was able, for reasons previously mentioned. Here in UK now teenagers have to remain in education until they are 18. The three years from 15 to 18 seem to me to be almost 'higher education', but compulsory.  How much they learn at school now I've no idea. 
My feelings are, and yes ok i cannot put proof to these feelings, but, my feelings are, that all forms of higher education are advised against by the GB and the JW Org. Some of you may have some proof of this in writing. So, where does this leave JW's ?
If a young person leaves school to go into full time 'service' ministry, they do not get a higher education. Their 'basic' education may have been just that, very basic. They are then not 'qualified' to talk to others on a higher education level, and this might even be to the point of not understanding such things as are being discussed on here lately. 
( Much of what is being discussed leaves me miles behind. I'm a very simple person. Plus at 69 I forget more than i learn. Yes I do write lots of notes and have books for recording different things, but the mind boggles. )
With respect for those I knew and loved in the past, within my ex congregation, many of them were 'simple country folk'. And I think Tom said about not having the time or inclination to do research online or or otherwise. So let us go back to the scripture at the top. 
So many questions. Does God reveal more to those of a lesser education ?  Is higher education and greater knowledge a disadvantage when wanting to serve God properly?
Or is it that those of higher education are too stubborn to learn God's way ?  Too proud maybe ?   
There are many things that the Bible doesn't tell us. is that deliberate ? Does God want to keep it simple for us ? So, should we pursue more knowledge about worldly things ? 
A problem may occur when talking to others about God, in that they may have more knowledge on a certain subject than we do and therefore believe something different. Should we then educate ourselves to their level on the same subject, or just pass them by ?  Bearing in mind the scripture at the top of this page. 
There has to be a balance of course. But my feelings are that the GB would like JW's to be educated only by the Watchtower studies and by the 'workbook' evening meeting studies. And of course by personal Bible reading.   But do JW's do as they are told in this respect or do a lot of them 'educate themselves', or take further education elsewhere ?

Amazing that regardless of wealth or political system some countries give similar results. For example North Korea scored at 106 on average and South Korea did the same 106. And that is among the absolute top of the world. 
So for a good society average high IQ in it self does not guarantee that. High IQ is useful for solving tasks. But if an evil person has high IQ, then he can do much damage. I would say that a kind person with low IQ is better than an evil person with high IQ.
We are all members of the same body as the Bible says and every type of person can be valuable for the society and for God.
 

A sage quote on getting through life's transitions. "Ride the horse in the direction that it’s going." Journalist Carole Radziwill said this to me at a very transitional part of my life. I believe the quote originates from someone else, but her words hit me like a bolt of lighting. If something isn’t working, don’t force it. That applies to love, work, life, everything."

Remember your value and your values. My parents divorced when I was 3 years old, so I was raised by two women—my mother and my grandmother. They were "wellness people" before "wellness" was a commonly used word. Specifically spirituality, resilience, gratitude (and vegetables!) were things instilled in me from a very early age and have shaped who I am as a father, husband, entrepreneur, and CEO.

Summary:
Scientists have made a major advance in understanding the genetic underpinnings of intelligence. Using a large dataset of more than 78,000 individuals with information on DNA genotypes and intelligence scores, the team discovered novel genes and biological routes for intelligence.
Intelligence is one of the most investigated traits in humans and higher intelligence is associated with important economic and health-related life outcomes. Despite high heritability estimates of 45% in childhood and 80% in adulthood, only a handful of genes had previously been associated with intelligence and for most of these genes the findings were not reliable. The study, published in the journal Nature Genetics, uncovered 52 genes for intelligence, of which 40 were completely new discoveries. Most of these genes are predominantly expressed in brain tissue.
