The g-factor Paradox

If IQ is heavily influenced by genes, then how do we explain the Flynn effect? Either we are improperly quantifying g or improperly measuring environmental factors.

 "Idiocracy" is a Problematic Anti-Poor Film

Unlike other films that satirize the media and the soul-crushing consequences of sensationalized entertainment (my personal favorite being 1951's Ace in the Hole), Idiocracy lays the blame at the feet of an undeserved target (the poor) while implicitly advocating a terrible solution (eugenics). The movie’s underlying premise is a fundamentally dangerous and backwards way to understand the world. The origin story for Idiocracy’s future world of half-wits is that uneducated people in the e...

 Why Correlate IQ and Race?

...the question of the relation, if any, between race and intelligence has very little scientific importance (as it has no social importance, except under the assumptions of a racist society) … As to social importance, a correlation between race and mean I.Q. (were this shown to exist) entails no social consequences except in a racist society in which each individual is assigned to a racial category and dealt with not as an individual in his own right, but as a representative of this catego...

 Scientific Reasoning Explains Increases in IQ

The bombshell is that the Flynn Effect is almost certainly environmental. Natural selection has a speed limit measured in generations, but the Flynn Effect is measurable on the scale of decades and years. Flynn was also able to rule out increases in nutrition, overall health, and outbreeding (marrying outside one’s local community) as explanations for his eponymous effect.241 Whatever propels the Flynn Effect, then, is likely to be in people’s cognitive environments, not in their genes, d...

 The Biggest Gains in g

It is one thing if a child’s IQ is elevated over time because she is drilled daily on vocabulary and basic number facts (two of the subtests of major IQ batteries). But Flynn and others have shown that these are not the areas where IQ has risen much. It is in what Flynn refers to as “on-the-spot reasoning” about relations between objects that are either totally familiar to everyone, hence no one can be claimed to have a prior advantage (e.g., arranging familiar pictures so they tell a c...

 <em>g</em> Presumes Unidimensionality

 In a multidimensional set of interrelations among tests, one axis can be found that accounts for as much of the interrelatedness as possible, even when it is known that more dimensions are required. The g-men have defined that largest dimension as g. They haven’t discovered it, as they are fond of saying, any more than the Greenwich Meridian was discovered by the International Meridian Conference in 1884. Any set of interrelated tests has to have a largest dimension, so under this d...

 BIDS Approach to Understanding Intelligence

There is nothing really the matter with the concept of g; it is just that we have misused it by making it the omnipresent concept in our study of cognitive abilities. Intelligence is important on three levels, namely, brain physiology, individual differences, and social trends (collectively, BIDS). The core of a BIDS approach to intelligence is that each of those levels has its own organizing concept, and it is a mistake to impose the architectonic concept of one level on another. We have to ...

There is one way in which individuals can make their own luck. Internalize the goal of seeking challenging cognitive environments — seek intellectual challenges all the way from choosing the right leisure activities to wanting to marry someone who is intellectually stimulating. The best chance of enjoying enhanced cognitive skills is to fall in love with ideas, or intelligent conversation, or intelligent books, or some intellectual pursuit. If I do that, I create within my own mind a stimul...

 Rolling Triggers and Social Multipliers Explain the Flynn...

The most potent facet of our environment is other people. When something, perhaps the popularity basketball got from television, triggered greater participation in basketball, the average performance rose as individuals played more and got better. Initially, a few people learn to shoot with either hand, then others imitate them. The rise in average performance feeds back into a new challenge for each individual. Those who want to excel have to learn to pass with either hand and this spreads a...

 Flynn-Dickens Model for IQ Gains

Take those born with genes that make them a bit taller and quicker than average. When they start school, they are likely to be a bit better at basketball. The advantage may be modest but then reciprocal causation between the talent advantage and environment kicks in. Because you are better at basketball, you are likely to enjoy it more and play it more than someone who is bit slow or short or overweight. That makes you better still. Your genetic advantage is upgrading your environment, the am...

If g-factor is inherited, then how do we explain the Flynn Effect? This model suggests genetic advantages translates into environmental advantage, the environment feeds back to become more challenging.

 IQ is Malleable

IQ is malleable. IQ has been shown to vary over one’s life span, and it is surprisingly vulnerable to environmental influences. It can change if one is stressed, old, or living in a different culture from the testing majority. A child’s IQ is influenced by his or her family, too. Growing up in the same household tends to increase IQ similarities between siblings, for example. Poor people tend to have significantly lower IQs than rich people. And if you are below a certain income level, ec...
