Indeed. Tanier's article in my link touched on research that said there was evidence that "conditional spanking" had some positive affect.

However, I don't think Peterson falls into this category (from Howard's article):

Dr. Baumrind described findings from her own research, an analysis of data from a long-term study of more than 100 families, indicating that mild to moderate spanking had no detrimental effects when such confounding influences were separated out. When the parents who delivered severe punishment -- for example, frequently spanking with a paddle or striking a child in the face -- were removed from the analysis, Dr. Baumrind and her colleague, Dr. Elizabeth Owens, found that few harmful effects linked with spanking were left. And the few that remained could be explained by other aspects of the parent-child relationship.
Stunning that if you remove the worst cases, the results are not as severe and "could" be explained by other factors they were unable to control for.
