) -- Go to a dating site and you'll see a zillion lonely hearts who yearn for long walks on the beach and cuddles before a fire, and the sites' new-member questionnaires are full of queries on exercise habits, political views, feelings about children and other, well, irrelevant issues.

Because what really matters is credit scores.

At least, that's one implication of some


on what makes for a solid marriage. People who enter a marriage with similar credit scores have a much better chance of going the distance than partners with scores that are very different, according to a study by two Federal Reserve Board researchers, Jane Dokko and Geng Li.

It's long been understood that money and children are hot-button marital issues, but until now there's been no rigorous academic research on credit scores.

"Credit scores convey unique and often unobserved information about consumers, including their loan payment histories and default behavior, as well as their levels of indebtedness and tastes for debt," the researchers conclude.

All those other characteristics, such as political and religious views, do matter. But the research suggests that even spouses compatible on many levels face a bigger chance of trouble if they aren't financially simpatico.

A poor credit rating, for example, can be the result of sloppy bill-paying habits rather than a true lack of trustworthiness. You can make your credit score better, and that's a lot easier than making yourself taller or more exotic.

So any prospective couple would be well advised to discuss financial habits and philosophies, savings habits and so forth. And it pays to set up an

What do you do if you cling to the romantic notion that opposites attract? Before the wedding, the researches suggest, get some counseling -- the financial kind.
