IQ Distribution in the United States- Batman and Robin

This posting is inspired from the behavior of my two pet cats- Batman and Robin. These two are Tuxedo cats, Domestic American Breed. Both are neutered male and almost over two years old. Robin is 2 months younger and smaller, but more dominant. Batman is older and slightly heavier but is the less dominant of the two. Robin loves the outside patio watching the squirrels, whereas Batman like to stay indoor and just stare the outdoors from the patio screen door.  Robin is a smart Cookie, meows frequently for attention and like to cuddle. Batman is the exact opposite. 

One event illustrating the difference in the intelligence between the two. Last year, I have a contractor installed a cat door in my apartment. In about 2 weeks, Robin learned how to use it both ways. On the other hand, Batman just learned how to use the cat door, one way just the other day.  I am still hoping, he learned to use it both ways when the warm weather kicks in the next few months. 

I kept wondering how many people are smart like Robin. how many are slow like Batman and How many are in the middle-just average.  As a result of this observation and behavior from my 2 cats,  I search on the IQ of Americans. Here's what I learned from my search. 

Our analysis of the available data covering educational achievement and test scores found that the smartest U.S. state is New Jersey, and (sorry to this state) the dumbest one is Idaho.

New Jersey’s total score of 337.8 was safely ahead of No. 2 Utah, with its score of 324. Idaho had the lowest score at 79.5, with the next lowest being Oklahoma at 97.8. Among all states, the average score was 221, and 27 states scored above that mark. For Details visit,  https://www.safehome.org/smartest-americans/

My Question: Are IQ and income correlated?

Answer: People with higher incomes also score higher on IQ-tests -- up to a point. At high incomes the relationship plateaus and the top 1% score even slightly lower on the test than those whose incomes rank right below them. This suggests that one cannot infer high intelligence from high income. Here's 

A brief review of IQ average by state

Conclusion: The vast, vast majority of Americans (83.9% in fact) fall between 85 and 145 IQ which is average to super genius. A fairly small portion of the population trails behind in the 55 to 85 category so I think we can safely conclude that the average American is a pretty smart cookie.

Lastly, My Joke and Food For Thought for Today!  and Here's information on Holy Week. 

Holy Week commemorates the seven days leading up to Easter. It begins with the commemoration of Christ's triumphal entry into Jerusalem on Palm Sunday, marks the betrayal of Jesus on Spy Wednesday, climaxing with the commemoration of the Last Supper on Maundy Thursday and the Passion of Jesus on Good Friday. Wikipedia  Date: Sun, Apr 13, 2025 – Sun, Apr 20, 2025
