This blog post was published originally in September 2011. Unfortunately, since that time the journal of Basic and Applied Social Psychology has retracted the article. The information on that retraction a can be found on their website. It goes without saying that we can infer no information from the relationship between a woman’s name and her income from this research.
Taking her husband’s name at marriage suggests to potential employers that a woman is less intelligent, less ambitious, inclined to work fewer hours and more focused on family. Recent evidence suggests that women who make that choice can expect lower wages and fewer job offers as a result.
