Jack Naglieri, research professor at University of Virginia:

improved theirِ IQs), whatِ they’reِ reallyِ doingِ is toِ makeِ people function better.

Richard Nisbett, professor of psychology at the University of Michigan:

But IQ] tests give youِ theِ sameِ answer toِ a veryِ substantial extent, evenِ over a period ofِ year.
Also, theِ average IQ ofِ people isِ changing overِ time.
Stephen Ceci, professor of developmental psychology at Cornell University:
Absolutely. And there’s plenty of evidence documenting this.
An article inِ November inِ the journal Nature byِ Price andِ her colleagues isِ one example.
Price andِ her team gave themِ IQ tests, tracked themِ forِ four years, andِ then gave themِ IQ tests again.
These changesِ in IQ scores wereِ notِ random — theyِ tracked veryِ nicely withِ structural andِ functional brain imaging.
Alan S. Kaufman, clinical professor of psychology at the Yale University School of Medicine:
There’s noِ such thingِ asِ anِ IQ.
But asِ soon asِ you goِ to a differentِ IQ test, thenِ theِ range isِ evenِ wider, becauseِ different IQ tests measure slightly differentِ things.
But whileِ thereِ isِ no single IQ – it’sِ a range ofِ IQs – youِ canِ still pretty muchِ determine whetherِ a person isِ goingِ to score roughly atِ a lowِ level, orِ anِ average level, orِ a high level.
First I thinkِ itِ isِ important toِ distinguish betweenِ atِ least threeِ differentِ meanings ofِ the word intelligence.

Your cognitive functions canِ beِ made toِ work moreِ efficiently.
