You guys might have gotten the Lake Wobegon version?
Here's a good g-factor
Since this thread likely came about from the recent repost
, maybe I should elaborate a bit on my "position" regarding intelligence testing.
I used to be really into this stuff. I've taken every test available on the internet as of about 10 years ago. Yet now I don't think there's more insight [for me] to be found from such tests ...
From that I draw the conclusion that there are different kinds of intelligence, e.g. vocabulary, numerical, factoid, pattern, short-memory, geometric, ... depending on your strengths, you'll score higher in some tests than others just because you're better at what the test is asking for. For example, my undergraduate math/phys team took at rather elaborate test that was mostly numeric and scored between 135 and 163 ... In retrospect these freshman scores actually turned out to be rather predictive (low-end became HS teachers, high end became researchers). Now these are already 3-4 sigma scores but that is to be expected when you're asking people who made it in the hardest of the hard sciences. I.e. 1 in 1000 for that particular skill.
Second, some of this stuff is trainable even though it's not supposed to be (the g-factor argument). If you're in the habit of dealing with IQ-test like questions, you'll naturally do better on IQ-tests. In that sense, the brain is like a muscle. You have natural talents but you can also train to max out your potential.
Ultimately, I've come to the conclusion that intelligence is less about solving silly puzzles and more about making smart decisions. In that regard, having already thought things over constitutes a significant advantage over making s*** up on the fly---which essentially is what the IQ test is testing. IOW, anyone who is in the habit of pondering things and investigating a lot will have a significant advantage over someone who is merely a fast thinker. It's very hard to beat a head-start with speed. A slow thinker who has spent 4 hours pondering something will beat a fast thinker who has spent 10 minutes anytime. A slow thinker who has read 3000 books will beat a fast thinker who has read 500 books anytime.
This also suggests that as long as one is of reasonable intelligence (e.g. 120+), it's possibly to crush higher intelligence(s) in terms of making intelligent choices by simply having the right decision making system. Seems to me that most don't bother to develop such a system. Also called lattice-work. So there's your advantage ... get to work!
What g-factor measures is the ability to put together complex patterns and hold this pattern in the mind long enough to crystallize it. This is likely neurochemical! However, picking up an already crystallized thought from someone else is much easier. As long as you actually make the effort. However, even high IQ people don't tend to do that.---Which is why Mensa discussion threads tend to be rather ... unremarkable.
PS: FWIW, I scored 134 on the Mensa test above. I bet several of you can do better than that, especially JasonR
