Interesting paper (even if it has gratuitous references), perhaps a suggestion to make IQ tests higher-stakes without changing the tests is to make the results publicly announced in front of a peer group.
Nevertheless IQ isn't useless and I'm still skeptical that the underlying g-factor, crystallized intelligence, and fluid intelligence can be changed very much--N-back training is always fun to read about. To quote Dr. Rob: "There are countless criticisms of I.Q. testing, some valid and some asinine, and it’s more important to think of I.Q. as a scoring range rather than a specific number. That said, few could reasonably argue against the notion that a score of 51 suggests severe intellectual impairment." http://shrinktalk.net/?p=515 http://shrinktalk.net/?p=515
- aik 16y agoHave you done much n-back training? Notice a difference? I've spent a little time and can see how it could help, but haven't spent enough time yet.
- Jach 16y agoI haven't spent that much time on n-back training either, though I am planning on doing a before-and-after comparison with a run of at least a month doing it daily, I'll start that in a couple weeks once things settle down here. I do think what I've done sporadically though helped with a recent C design involving lots of linked lists. http://www.gwern.net/N-back%20FAQ.html http://www.gwern.net/N-back%20FAQ.html is the best reference/about I know of for the subject. Some people report improvements in daily life like grokking math better, others report nothing even after months of training.

Or met a chronic alcoholic? Fluid intelligence can definitely be changed. It's just a lot easier to do harm than good.
- Jach 16y agoTouché. I'll just pretend I said "changed upward". ;)
- xiaoma 16y agoActually there are a few things that have a measurable upward effect. One of the better documented ones is running an hour a day. Not only does it show measurable improvements on intelligence tests (for both rats and humans!), but it increases the rate of neurogenesis. Slightly less certain, but still very compelling is the research related to taking up a musical instrument as a child. I'm confident that it's just a matter of time before we have more targeted training regimens and smart drugs that are both powerful and safe.
