on the dimensional nature of a point of IQ score

A question from a correspondent:
Hoping you can provide guidance or reference with respect to the scale upon which IQ points are enumerated.
I have been unable to locate any reference that can tell me if a 10 point difference in measured IQ is the same relative difference across the entire range.
In other words, is the IQ scale linear or not? the 10 point difference between an IQ of 60 to 70 the same intellectual difference in a 10 point difference between 125 and 135 for example?
I have never been able to find anything that would provide me insight into the measurement along these lines.

abelard has replied:
It is impossible to say. IQ is not a measure in the same manner as an inch is a measure.
Further, you cannot claim that any particular IQ [test] question measures the 'same' amount/quantity of IQ as another question.
There is no such thing as IQ, only scores marked from a sheet of questions - and then comparisons made between varied scores.

Whilst statistical modelling suggests that the strength of the data is Category 4 in this list (Comparing predicates, relational strengths), this is very far from the case in the real world.

IQs are assumed to fall at random, that is on a normal distribution curve.

See also intelligence and madness
             (with calculations described in great detail here:
              writing down stats - distribution of a random variable : using the standard normal distribution table),
     and statistics and intelligence

You might like to familiarise yourself with the statistical meaning of the terms 'validity' and 'reliability'.

Much of the blithering about IQ is somewhere between dubious and vanity.

why god became man - "I believe in order that I may understand"

Said by Anselm, circa 1080.

The statement, "I believe in order that I may understand", is interesting logically.

Anselm was a brilliant early logician, but no modern empiricist.

Anselm was the inventor of the ontological argument (primarily expounded in Proslogion), which many still try to defend to this day.


Notice that the belief in why god became man (to redeem us from sin) is not questioned by Anselm. Instead, he makes every effort to support the belief by logic.

You will meet logic used in this manner every day, as humans try to rationalise their beliefs and interests.


Precised from Davies, Evans, p. xviii:

Anselm's argument was that god had been dishonoured by human sin.

God's being was challenged by the falling away of humanity.
Because god is all-powerful, he could not let that continue without doing something about it. Otherwise he would not be what he should be.

[Notice this concept of 'honour', projected from feudal concepts of human honour.]

God could have restored humanity to sinlessness by his own action from his infinite power, but that would not have restored right order because the sin was humanity's, not god's.

Humanity could not put things right because, although it owed the debt, it lacked the power.

Anselm then considered whether an angel could have acted on behalf of humanity but rejected it because,
1) the angel would not be the debtor and
2) angels are individually created, whereas humans are linked by birth.
Thus, a man can act on behalf of humanity, but an angel cannot.

Thus, the only remaining possible solution is for god to become man. For the god man would both have the power and the position to redeem humans.


In view of responses from readers, here is another way of describing this. The points are:

  1. Logic and predicates (assumptions) are entirely different animals.

    Predicates are better tested by empirics, not by 'logic'.


  1. Most people still don't understand that difference.
    For instance, they base reason on Marx's (socialist) many flawed assumptions and try to built 'logic' on that unsound foundation..

Going beyond this, even the 'logic' used in Western society is deeply flawed inasmuch as it contradicts empirics.
See Why Aristotelian logic does not work.

political correctness is stunting free speech

Donald Trump's statements concerning the street violence is reasonable and correct, so every lefty rushes to distort his comments.

Now in the UK, we have a Socialist politician who says that jihadi Islam is 'right wing', a perfectly reasonable statement. So she is drummed out of her position in the Socialist Party!

Monopolistic business:
A google employee was sacked for correctly stating scientific research concerning sex differences.

In each case, Lefties are falling over themselves to shut down free speech and to lie about the speakers.

Unfortunately, some right-wingers are foolishly pandering in each case. Such is the chaos in 'education' generated by the Blob.

Down the memory hole is it conflicts with the agenda.

Socialists seek to shut down free speech as the seek their 'people's' dictatorship.

"In a time of universal deceit - telling the truth is a revolutionary act."

don't worry too much about jihadi loons—short skirts and hot pants now everywhere in spain

"Nan Farrow was born in Beeston, near Nottingham, in 1904. Her father had been a manager of a factory and after he lost his job the family lived in poverty.

"At the age of fifteen she found work in an insurance office. Nan became interested in politics and joined the Fabian Society. She met and married George Green, a musician. The couple had two children. Her father was furious with her for "tying herself to a wandering musician".

"In the early 1930s Nan and George Green joined the Communist Party of Great Britain. On the outbreak of the Spanish Civil War George Green joined the International Brigades.

"In 1937 Nan arranged for her two children to go to Summerhill and she went to Spain as an administrator with the British Medical Aid Unit, an organization that had been set-up by the Socialist Medical Association and other progressive groups. Nan served under Len Crome, chief medical officer of the 4th Army.

"She later recalled that on her arrival in Spain "I was introduced to my job: Assistant Secretary. The chief Administrator was British, as were the surgeon in charge, theatre sisters, ward sisters (who included three New Zealand nurses) and one or two ambulance drivers."

"Nan Green worked at the convalescent hospital at Valdeganga. She helped to organize Saturday night dances for the patients and local people: "Half or more of our patients were sufficiently mobile to dance, but there was great difficulty about partners for them. Village girls in those days could not be touched before marriage by any man other than their fathers or brothers, and to have danced with a stranger was likely to ruin their chance of a husband."

exploding snowflake heads

A google employee has been sacked for honesty and fact-founded analysis.

He counters the leftist (google) heresy that men and women are equal:

"On average, men and women biologically differ in many ways. These differences aren't just socially constructed because:

They're universal across human cultures
They often have clear biological causes and links to prenatal testosterone
Biological males that were castrated at birth and raised as females often still identify and act like males
The underlying traits are highly heritable
They're exactly what we would predict from an evolutionary psychology perspective

Note, I'm not saying that all men differ from women in the following ways or that these differences are "just." I'm simply stating that the distribution of preferences and abilities of men and women differ in part due to biological causes and that these differences may explain why we don't see equal representation of women in tech and leadership. Many of these differences are small and there's significant overlap between men and women, so you can't say anything about an individual given these population level distributions."

Warning - do not fight the leftist agenda with facts and analysis.

Modern snowflake analysis is founded on 'feelings', not facts. Feelings are worth far more than facts.

Be modern and stop thinking and reasoning. Raise personkind to a new higher level of consciousness, where facts can be abolished to the empowerment of us all.

Vote for Hiliary and Corvyd - and google.
