Please read my prior comments on this subject. You are confused.

While I do not think the "constant competition" suggestion is a good idea for schools (per my initial reply), it is obvious that someone will always lag behind, with or without competition in schools. Humans do not and cannot perform equally. When students exit their schools, they will face...

The cognitive demands of scholastic items vary according to the process involved in learning the underlying material (learning by eduction is highly g-loaded) and the nature of the extent of g-loading for the category of the test items. In all cases, the drift in raw scores has been zeroed out...

Let me remind you of the prior dialog: The proper use of a preposition includes the use of an object of the preposition. In the ugly sentence, the preposition "at" does not have an object. This is a grammatical error. Do you read books that use the word "at" without an object? If so, do...

I am not sure what it means for g to be adaptable. At the individual level, g is highly heritable, ranging from about 70% of the variance in middle age to 80% in the elderly. The only environmental factors that influence g in adults are those that are chemical or biological (the intrauterine...

I assume you are referring to the Lynn-Flynn Effect. The secular increase in IQ scores has not been shown to reflect an increase in psychometric g and is apparently entirely the result of gains in specificity in some group factors. “When the g loaded test is composed largely of...

punishing students for low intelligence And the winners and losers would be determined by their respective IQs. Your idea would have some merit, if we had a multi-rail educational system that would separate students according to ability. A person with an IQ of 85 has no chance of equaling a...

More myelin usually means faster NCV, which in turn means higher intelligence. Among the mechanisms that may cause that gain are the reduction in neural noise and increased efficiency of brain transmissions (explaining why more intelligent brains consume less energy). Faster NCV is presumed to...

What is your point? Do you wish to have us believe that the genetic lines of US blacks are depressed because their ancestors were less intelligent than other blacks? Is it your belief that blacks in the US are less intelligent than blacks in the countries where their genetic roots lie? What...

It would be helpful if you quoted my exact words. I don't recall which message contained the comment, but I believe I did not state that this was a universal situation, nor did I say that repeated use of a test was necessarily going to give higher specificity. I believe I commented that some...

Neural noise presumably causes the brain to work harder to perform any given function, as is demonstrated by observing glucose uptake. As problem complexity increases, the brain has to call upon more resources, thereby increasing its neural noise load. When retransmissions are required, Miller...

Wrong. I read the paper you referenced when it was published and have met the author. While accusing me of ignoring material, you elected to edit out the following: The Flynn effect comprises elements that you apparently do not wish to take into consideration or which you have not...

myelination The hypothesis that was referenced bases a significant part of its explanation on the role played by myelin in reducing the impairing role of neural noise in cognitive activities. The findings that RT as measured by ECTs correlates negatively with intelligence can be interpreted...

When someone tells me that something I have presented from established findings has been refuted, that person must understand both the material he is challenging and the material he believes refutes it. Otherwise, he is guessing. You are guessing. So, list for us the evidence that makes the...
