Raising IQ != raising intelligence. If I take the same test over and over, my IQ goes up, but my intelligence stays the same. If I give testees half the answers, their IQs go up, but they didn't get smarter. You get the point. http://arthurjensen.net/wp-content/uploads/2014/06/Raising-IQ-Without-Increasing-g-Review-of-Howard-L.-Garbers-The-Milwaukee-Project-Preventing-Mental-Retardation-in-Children-at-Risk-1989-by-Arthur-Robert-Jensen.pdf …https://twitter.com/WiringTheBrain/status/928182568696143872 …

Biologically, learning literally changes the neuro network, building new and denser connections. How could it not change intelligence?
Taking the same test over and over does not increase your ability to solve new, unrelated problems. That is what general intelligence is (psychometric school). If you think so, I recommend that you spend at least an hour a day solving Raven's matrices. ;)

Basic logical argument: Intelligence is a function of brain structure and organization. Brain structure/organization can be altered via experience/stimulus. Therefore, intelligence can be altered via experience/stimulus.
-
Sound, but does not imply that it is practically feasible to increase intelligence by re-taking tests or WM training. I'm mostly hopeful for chemical interventions and gene editing of adult-active genes.

Sure, I am not saying it is, and that is a poor way to simulate "learning" (even through I routinely make my own students retake exams until material is mastered). But there is plenty of evidence that introducing the brain novel stimulus benefits brain function
-
It is. But that was precisely my point. One cannot assume that changes in IQ reflect changes in general intelligence is any simple way. Need ratio scale measurements for that. But one can examine it with fancy psychometrics.

I was more speaking to "learning" in general. What is memory if it is not a physiological change in the brain? How can building new networks not improve the ability to think?
-
Neuroplasticity is a trivial finding. Unless one believes in Cartesian souls, any change in the mind must obviously be a change in biology of the brain. Be careful about terms like "ability to think". I was talking about general intelligence.
