The use of intelligence in many senses makes =

your problem a little confusing. In a real grid
we might find such construct labels. For now,
let's refine the labels a little for clarity's sake, =

understanding that in an actual grid the labels =

would be irrelevant- as far as the math goes. If =

we were conducting a grid study we would not =

need to refine these labels but for illustative
purposes it will help.
Lets change "Intelligence vs Foolish" to =

"Wise vs Foolish".
change "Foolish vs Careful" to =

"Careless vs Careful".

change "Intelligent vs Incompetent" to =

"Competent vs Incompetent"

keep "Intelligent vs Stupid"
The causul model is"( leaving off the contrast poles =

for illustrative purposes)
+ =3D Wise
Or =

Intelligent + Careful=3D Wise

with competent not entering the equation. =

Note that the configuration does not require that =

Competent be uncorrelated with Wise. It may or =

may not be. Both Wise and Competent may =

share a common source in a fourth variable; =

Educated. If they are so rooted in Education, =

Wise and Competent would be correlated =

dependent variables. They would be correlated =

but without any causal connection between the two. =

In grid form we might ask a person to rate or rank =

50 persons (elements) along the 5 constructs.
Grid Elements (N=3D50)
Mary Willie Joseph ........ Mike
Intelligent 1 5 4 3
Competent 3 7 1 1
Careful 7 6 2 5
Wise 5 5 1 4
Educated 1 4 7 7
These numbers are just random and not meant at this =

time to simulate real formal causation. =

In the real world we would be interested in discovering =

if the client is implicity synthesizing any of the =

constructs from the other constructs. We could also =

concatenate many peoples grids, so long as they =

all rated using the same constructs. Their elements =

could differ. If we contrasted two groups of people, =

say academic failures and the academically successful, =

we might find the two groups synthesize the constructs =

in different ways. =

Of course we would not be limited to human elements.
We could use musical compositions, commercial =

products, works of art, feelings, or what ever.
Does this help set the stage?
