Correlation is not causation. Every study like this, that fact should be in bold red caps at the top and the bottom of each page.

For all we know it is just as possible that the correlation exists because happiness tends to lead to marriage (who wants to get hitched to a sourpuss?), as marriage leads to happiness. Or some other factor might cause an increase in both happiness and marriage (such as, oh, say, having a sane/conservative perspective on life), but not link marriage and happiness together directly.

Therefore, if they use data like this to push for gay "marriage," that would be irresponsible and unfounded.

We really need to be giving kids basic logic in elementary school, I'm tellin' ya...

Correlation is not causation.

Absolutely correct. But in this case there are strong common-sense reasons to believe that there's a causative component. People spend billions of dollars trying to attract and keep mates, and presumably they have some idea what they want, so it would be very surprising if finding a partner didn't increase happiness.
