Hi Mike
first of all, I would be interested if you can build a measurement model between both sets of items – either all of them load on
an overall g-factor, or the test items load on a g-factor and the g-factor has an (regression) effect on the g-perception-factor.
It is this relationship which is, in my view, interesting. Further, in case you have a very good and large sample, information about this
relationship could be used n further studies to set up a model of g by just relying on self-reports (by fixing error variances in such a way
that you measure actual g with the self-report.
Best,
Holger

Betreff: [OB-LIST] Self knowledge as a discrepancy between objective and self-report data
For a sample of respondents, I have a self-report measure of cognitive ability (sample item: I have a better vocabulary than most people I know) and scores on a cognitive ability test. I am trying to locate a literature relevant to discrepancies between the two measures.
My questions are as follows:
1) What is the best way of expressing the discrepancy between self-reported and objectively-assessed cognitive ability?
2) What is the best way to characterize the meaning of the discrepancy? Some discrepancy would be expected from random measurement error in the two measures (both have alpha reliabilities near .80). If the discrepancy is not all measurement noise, I assume that it indicates a systematic error in the self-report measure. Is this error best characterized as a lapse in self-knowledge? If one's self-reported cognitive ability underestimates one's actual cognitive ability, is one modest, or both modest and lacking in self-knowledge? If one's self-reported cognitive ability is higher than one's actual cognitive ability, is one clueless (or perhaps a teenager)?
3) If one lacks self knowledge, would one's scores on a personality test be less predictive of a criterion than if one has accurate self knowledge (i.e., self knowledge as a moderator)? If degree of self-knowledge is an indicator of contamination in the measurement of personality, would self knowledge and the personality measure result in a regression suppressor situation when used to predict a criterion of interest (i.e., self-knowledge as an indicator of systematic error in another measure)?
4) Is one's degree of self-knowledge concerning cognitive ability a good indicator of the level of self-knowledge concerning other personal characteristics?
Comments on any of the above would be appreciated.
Mike
