Showing the Correlations between Various Measures of Intelligence
| 25 Juniors | 25 Seniors | |
| Correlation of psychological tests with estimated Intelligence | .70 | .53 |
| Correlation of psychological tests with Academic Records | .42 | .57 |
| Correlation of Academic Records with estimated Intelligence | .22 | .37 |
The most striking result here is the rather low correlation of the academic records with the other measures of intelligence. The psychological tests agree closely with the results of the estimates by associates. The correlation of the tests with the records is considerably lower, while the correlation of records with estimates is exceedingly low. The full significance of these results will of course depend on the attitude one takes toward the various measures. One who has faith in the value of academic records must of course reject the estimates of associates and be very sceptical of the value of the mental tests. But vocationally the estimates of associates must always have value, since these determine or indicate the reactions of others toward a given individual, and vocational success will depend to a considerable degree on these reactions. The ultimate value of the mental tests is still to be determined; in fact, it was partly in order to aid in their evaluation that these experiments were performed. Inasmuch as the tests and the estimates agree closely, the tests and the records less closely, while the records do not correlate to any marked degree with either of the two other measures, the significance of the academic marks, or their reliability in this instance, must be seriously called into question.

VI. Does the ability to judge the traits of others (judicial capacity) stand in any relation to proficiency in mental tests or to success in college work? The following table shows the correlation of judicial capacity in the case of each trait with standing in the tests and with academic records.
In the case of academic records there is seen to be absolutely no correlation with judicial capacity, in any of the traits estimated. In the case of the mental tests, only two of the traits yield high coefficients. In intelligence and in humor there is fairly high correlation (.55 and .48). The suggestion here is that those who do well in the mental tests are good judges of the intelligence and the humor of their friends, but that in the case of the other traits there is no necessary or probable relation.
Question VII. Is the individual who is a good judge of others also one whose self-estimates have high reliability? If the individuals are placed in an order of merit with respect to their judicial capacity in estimating the characteristics of their friends, and placed also in another order of merit on the basis of the accuracy of their self-estimates, what relation will be found between the two arrangements? The following table gives the coefficients of correlation when such arrangements are compared in the case of each of the traits.
