[This is the transcript of my regular KVMR commentary broadcast on 20 June 2018.]

Listeners to these commentaries over the years have heard me report on the advance of America’s national dumbth – a term coined by the late Steve Allen to describe the overall state of our understanding, interests, and intellectual acumen.  The reasons for this have been many, but mainly due to the de-emphasis of rigorous academics in our public schools over the last fifty years or so.  In any event, I was surprised to receive from a correspondent news of recent studies on the decline of IQs reported by our National Academy of Sciences, and other similar organizations in the developed world.

Ongoing longterm studies in Denmark, Britain, France, the Netherlands, Finland, and Estonia all corroborate the “downward trend” observed here in America.  First, let’s be clear that what we are talking about is not how much people know – people’s so-called knowledge base, which, of course, has also been declining over the same period.  But IQ is a prime measure of a person’s ability to process data, acquire knowledge, and make decisions.  This human attribute is critical to a society, especially technologically advanced societies, in that it directly impacts people’s ability to participate in our rapidly changing job markets.

During most of the last century our IQ scores were found to be increasing, something that came to be called the Flynn Effect by psychologists and people who keep track of such things.  IQ scores for men kept increasing until about 1975, and then something unexpected happened.  Continued testing showed that IQ scores started steadily decreasing among men born after 1975.

Detailed analysis showed that the decline was not due to a “long-believed theory known as the dysgenic fertility theory, which states that unintelligent people have more children, leading to a ‘dumbing down’ of society.”  No, research shows that the dumbing down was identified as caused by “environmental factors (which) could range from nutrition, changes in the educational system, less reading and more time spent online, (and) to changes in the media environment.” (more here, here, and here)

Others have acknowledged that we may also need to adapt IQ testing and “other traditional methods of measuring intelligence”, since times have changed and today “people are exposed to different intellectual experiences, such as changes in the use of technology, for example social media” which indicate that “educational methods need to adapt to such changes.”  But the bottom line is still that, in the aggregate and compared to their older generations, today younger people cannot do and/or readily learn to do the things that need to be done to operate a civil society.

These observations across a broad swath of developed western countries should sound an alarm that something has gone wrong with the way we as parents raise kids, and then how we as a society educate them to become the next generation of a productive, competitive, and advancing civilization.  However, there is also a danger that these warnings will be ignored or actually denigrated by political factions for reasons ideological that dictate a more homogenous world.

One political vulnerability of such research is that it continues to corroborate the longstanding differences in IQ based on race, showing that the mean IQ scores of Asians rank highest, followed by Caucasians, with the Negroid scores being significantly lower.  The American Psychological Association acknowledges these rankings despite “the absence of any adequate explanation of it, either environmental or genetic.”  (more here)

Finally, a strong corollary of all this is the increase of mental illness among young people in developed countries.  Alarming fractions of our youth are now regularly diagnosed and medicated for clinical depression and behavioral problems. (more here and here)  Statistics on the need for remedial education and teen suicide rates all tell different parts of the same story.  Among things like our public education system, we may also want to reexamine and change the way that well-to-do parents are today required to monitor and restrict our children’s activities, and how among the poorer strata, where broken families abound, kids are turned loose to find their own way on the meanest streets in town.

My name is Rebane, and I also expand on this and related themes on Rebane’s Ruminations where the transcript of this commentary is posted with relevant links, and where such issues are debated extensively.  However, my views are not necessarily shared by KVMR.  Thank you for listening.
