Yet again, the prophetic documentary "Idiocracy" is unfolding before our eyes.
Americans’ IQ scores drop in four of five measurements
IQ scores significantly increased from 1932 through the 20th century all over the world, with differences ranging from roughly three to five IQ points per decade. This phenomenon is known as the “Flynn Effect.” Now, however, a new study out Northwestern University suggests a “reverse-Flynn Effect” of sorts may be taking place in the United States.
This reverse-Flynn Effect was present across a large U.S. sample covering between 2006 and 2018 in every category — except one. Still, there were consistent negative slopes among three out of four cognitive domains.
Ability scores pertaining to verbal reasoning (logic, vocabulary), matrix reasoning (visual problem solving, analogies), and letter and number series (computational/mathematical) all dropped over the course of the study period. However, scores of 3D rotation (spatial reasoning) generally increased between 2011 to 2018.
Composite ability scores (single scores derived from multiple pieces of information) were also lower across the more recent samples.
These score differences persisted regardless of age, education, or gender.
{That's all??}
Despite the observed decline in IQ scores, corresponding study author Elizabeth Dworak posits people shouldn’t read these findings and think, “Americans are getting less intelligent... “It could just be that they’re getting worse at taking tests or specifically worse at taking these kinds of tests.”.
.

.
This project did not attempt to determine the reason for the decline in IQ scores. That being said, researchers add there is no shortage of possible explanations and theories in the scientific community, ranging from poor nutrition, and worsening health to media exposures and changes to education.
.
.
.
A change in societal values may have also affected IQ scores, Prof. Dworak adds. “If you’re thinking about what society cares about and what it’s emphasizing and reinforcing every day, there’s a possibility of that being reflected in performance on an ability test,” she continues.
.....
{Yeah, I don't think measurements of verbal reasoning, matrix reasoning and basic math take into account diversity, equity, inclusion, virtue-signaling, one-way tolerance, anti-colonialism, critical-race-theory or dismantling the systemic institutional imperialist white cis-male supremacist capitalist patriarchy.}
Original article here... includes the statement, "The steepest slopes occurred for ages 18–22..."
Funny, if the data showed a great increases in IQ scores, I'm quite sure the academic pin-heads would be patting themselves on the back for showing how better our culture and education is.
But the opposite? "Gee, we need more money to see what might be causing this".
