defining fluid

a physics analogy.

distance:velocity:acceleration

knowledge:means of knowledge acquisition:fluid

this makes some sense to me... does this make sense to anyone else?

I believe the physical analogy is not regarding motion, but about the state of matter, as in the possibility of motion.

The counterpart of "fluid" in "fluid intelligence" is "crystallized" in "crystallized intelligence." In a way, this corresponds to "working" in "working memory," versus the declarative and episodic memories. One adapts rapidly to its surroundings (liquid), while the other is stable even when the environment is not (solid).

It seems like there is too much crossover between the different types of intelligence to make any general distinction.

I think Chase's (or was it Erickson's) research on chess players indicates that preexisting knowledge, crystallized, provides the basis of the difference between experts and novices. Since neither can recall the nonsensical patterns with ease but the experts can remember a legal board of chess pieces with incredible speed, it seems expertise is more a function of purposeful practice than fluid intelligence.

If we accept that working memory is a function of both crystallized intelligence and fluid intelligence, directed practice a better researched and more promising pursuit than increasing fluid intelligence.

To continue with our analogy: for the price of a slightly more efficient engine, we can probably by enough gas to get us far enough. All we need is persistence and hundreds of hours alone on the road.

Gc is positively correlated with Gf and Time.

Gc is obtained through the agency of Gf.

Increasing fluid (if possible) is the way to maximize efficiency. Low Gf with "purposeful practice" = inefficiency. Or as Biden so articulately put it in the VP debate, "the ultimate bridge to nowhere"... or at least somewhere not-very-quickly.

Time is the ultimate resource. Gf saves it.

But what is "intelligence"? ;-)

Is it that little o with a j -- a g? or something else? A number based on comparative population analysis of test-taking (where mathematicians are easily flung to the top of the scales) as it has been for more than a century?

Anyway, if you (OP) want the crux of the definition of fluid intelligence by way of comparison to crystallized intelligence (as cognitivefun kindly touches), go ahead and do a search on Wikipedia and follow up with more in-depth research elsewhere.

have little basis to understand "the ability to solve new problems independently of previously acquired knowledge"... gF

analogy attempts to understand how it surfaces

Gf..

As an analogue, I can see what you are trying to say.

Here's my version as a kind of variation on your theme:

Distance * Velocity = Acceleration as Knowledge * Ability to Gain Knowledge = Fluid (Intelligence)

But, when all is said and done, it is arbitrary and does seem helpful in cornering the question of what intelligence is in the first place.

Erratum; sentence should read: "...does NOT seem helpful..."

no, fluid is no acceleration
