Not Correcting for Restriction of Range can be Advantageous.

Gross, Alan L.; Kagen, Edward

Educational and Psychological Measurement, v43 n2 p389-96 Sum 1983

This paper compares an uncorrected with a corrected correlation between a selection test and a test-criterion in terms of expected mean square error (EMSE). It presents evidence that although the uncorrected may be more biased than the corrected correlation, it may have a smaller EMSE value, especially in small samples. (Author/PN)
