My point is that this sort of studies has been done over and over again, and they repeat the same results pretty much all the time. Have you ever heard anyone say that a good relationship is due to partners not talking and not having sex?<p>Ever since the myth of the &quot;obedient and silent wife&quot; was dispelled in the &#x27;60s and &#x27;70s, it looks to me as intuition and research in this particular field overlapped fairly consistently. The interesting question would now be &quot;<i>why do people not do this already, even when rational and well-educated?</i>&quot;. <i>That</i> would be noteworthy.<p>I don&#x27;t know, maybe the point of this research was getting down to the details (which they do, a bit), but the overall structure is the same as always.
