Poles of both sexes (on the far left) have the highest overall digit ratios in this sample, and Finnish men (far right) the lowest. Poles also show the least within-sex variance in ratios, and Finns and Hungarians the most. Intersex comparisons show that Polish women and men have nearly identical digit ratios and variance, and Finnish women are significantly more feminine relative to their male co-ethnics.
The chart suggests a low variance in the genetic fitness of Polish males, thus leading women to choose mates based on reasoning that has less to do with the man's genetic fitness. Speculation about this study on the Internet (heartiste.wordpress.com/2012/03/09/is-finger-length-ratio-evidence-of-a-womans-fidelity/)
Given that the study notes that reproductive success correlates with partners where the man has a lower 2D:4D ratio and the woman has a higher one, the implied conclusion is that Polish women are advantaged by mating with foreigners. This is suggested because amongst all the samples. Polish men apparently have 2D:4D ratios that are the most similar to those of Polish women -- which, according to the researchers, has a negative correlation with reproductive success.
Check out the study PDF as well as the blog post linked above... it's quite shocking!
