Some bad at math chinaman confused a chart that showed how different combinations of interracial couples made up the percentage of total interracial couples as being a chart that showed how likely different combinations of interracial relationships would end up in divorce. The article is protected and I don't have a wikipedia account to fix.

Here's the study he cites: http://onlinelibrary.wiley.com/doi/10.1111/j.1741-3737.2008.00582.x/full
I'd just delete the whole section as being pointless, but the relevant information is in table 3.
