Abstract: This article presents evidence strengthening the argument against comparison group strategies given the current state of knowledge. The comparison group for this study was drawn explicitly recognizing the self-selection issues. It drew youths from similar sources matched on attitudes related to California Conservation Corps (CCC) participation not usually measured and collected information explicitly designed to improve the statistical modeling of participation. Yet, as always, whether a comparison group strategy works is an empirical question. One believes the results from such a study only if they basically conform to one's prior beliefs, otherwise the suitability of a comparison group is suspect.
