Researchers propose that creativity is no longer limited by intelligence above a specific IQ level. Some studies show moderate correlations between intelligence and creativity in preschool children with IQ below 120 and a lower correlation in children with IQ above 120. Some other studies (using the WISC-R) found no significant correlations between intelligence and creativity with the exception of a positive relationship within the 131–145 IQ group. Using a different intelligence test (CAT), the correlations between CAT scores and creativity remained insignificant for most groups but were lower than those obtained with the WISC.
Which of the following, if true, most weakens the conjecture, creativity is no longer limited by intelligence above a specific IQ level, presented in the above argument?

A) Comparison of correlations of different dimensions of creativity at a particular IQ level does not show significant differences in the correlation values.
B) Evaluation of the CAT method and WISC method indicates that WISC is a more accurate measurement method than WISC.
C) A study proves that the IQ- creativity correlation is lowest for elementary school students and highest for high school students.
D) Meta-analysis to estimate the mean correlations below and above an IQ of 120 shows a significant difference between the two values.
E) A scatter-plot of the creativity scores and intelligence scores reveals a linear relation.

Let's look at each of the options one by one:

A) Comparison of correlations of different dimensions of creativity at a particular IQ level does not show significant differences in the correlation values.
comparing different dimensions of creativity at a particular IQ level rather than comparing creativity at different IQ levels makes it irrelevant.
Plus it doesn't show significant differences in correlation values.
Eliminated

B) Evaluation of the CAT method and WISC method indicates that WISC is a more accurate measurement method than WISC.
I guess author is referring either to
i) CAT being more accurate to WISC - well than it means 'creativity remained insignificant for most groups but were lower than those obtained with the WISC'
It doesn't weaken our conclusion but supports it that creativity is no longer limited to iq beyond a certain level
or
ii) WISC being more accurate than CAT - well it means creativity is showing strong correlation at a certain IQ level only (131-145) but through out it has found no correlation between the two (well IQ is measured between <20 to >140 with the extremes being an idiot (0<20) and genius(>140))
Can be questioned as other studies have shown lower correlation between the two above IQ 120.
Still let's keep this as an option till we go to others.
On Hold


C) A study proves that the IQ- creativity correlation is lowest for elementary school students and highest for high school students.
So?? We are comparing Creativity with IQ, not age/Education levels with IQ-Creativity association. Out of scope clearly
Eliminated

D) Meta-analysis to estimate the mean correlations below and above an IQ of 120 shows a significant difference between the two values.
OK. so now we have kept 120 as a wall and we compare mean correlations below 120 to those above the wall of 120. The result is a significant difference. It means they are not related. It isn't weakening that creativity is not limited to high iq
Eliminated

E) A scatter-plot of the creativity scores and intelligence scores reveals a linear relation.
This is a game changer for a simple fact that if we plot a scatter plot and we see a linear relation between variables Creativity and IQ scores, it means movement of one variable affects movement of another variable.
For the sake of argument, lets consider the the following two possibilities of linear trend:
i) Linear Trend is positive (as one variable increases the other variable also increases):
It means creativity is affected by IQ levels as it moves higher and thus correlation exists throughout
ii) Linear Trend is negative (as one variable increases, the other variable decreases):
It means creativity is negatively affected as IQ levels grow and thus again correlation exists as affect persists of one variable on another
Both the above cases give enough evidence to show that Creative has a strong correlation with IQ and will be affected with increase or decrease in IQ.
In other words we cannot claim that creativity will not be limited by Intelligence after a certain level as IQ is affecting Creativity at all levels either positively or negatively
Hence E stands to be the probable answer by the method of elimination.
