Had you dug deeper, you would have found even more gold:

The data sample comprised more than 1,463 men and 1,769 women who participated in the National Longitudinal Surveys of Youth. A majority of the individuals in the study, all born between 1957 and 1965, were members of the baby-boom generation. Participants’ psychological well-being was measured in 1991 and 1994 using a seven-item scale that assessed their levels of depressive symptoms.

Yeah. This is the NLSY79 cohort, queried about everything under the goddamn sun, as reported twenty six years ago. So the first real question is why, exactly, did they go with '91 and '94 when they've been interviewed every two years since. In other words, there are twelve data sets newer than the ones they used. Especially since it's a longitudinal data survey with a customer-facing front-end. You can literally query every dataset but '94 and older.

Where it gets funnier is if you wanna see their paper, you have to ask "the news bureau" to email it to you. It's not like you can just look it up - you have to beg one by one. And if you wanna see where that paper has spread, you get only the "marriage and religion research institute." Which has a gmail address, by the way.

Yet Fox not only snatched at this, they read it wrong:

New research at the University of Illinois examined data on nearly 1,500 men and 1,800 women between the ages of 52 and 60 and found that couples who resist traditional gender roles, or who shoot for a so-called equal marriage, are less happy than those who swim with the tide.

If everybody was between 14 and 22 in '79, they were between 26 and 34 in '91 and between 29 and 37 in '94. Most people would argue that the differences in aspect between 60-year-olds and 26-year-olds are substantial... but not Fox News.
