I'm surprised this passed peer review. The underlying studies seem pretty iffy, for example in a few of the studies that made the assumption that "nice car" == "upper class" and in others they had students self-assess social class status rather than using any of the normal socioeconomic classification approaches used in social research. (disclaimer: I'm not a psychologist, but I've read a lot of papers on social stratification as I used to work on social mobility stuff)
