Okay, let me make the connection for you. You made a completely unsubstantiated claim, "rarely do the spouces (sic.) have same STEM occupation". When others offered personal evidence refuting it, you hypocritically demanded empirical proof.
I offered an article which bolstered the anecdotal evidence ("A new working paper by an international team of economists finds that better educated people are increasingly more likely to marry other better-educated people while those with less formal schooling are more likely to choose a less well-educated partner."
This means that those with degrees, including STEM degrees, tend to pair with persons of similar levels of education (STEM and non-STEM). By reducing the number of non-degreed persons from the pool of potential mates, the chance of people pairing with a STEM degreed person increases. It's called assortatative mating.

So here is what you need to do. If you still think that STEM folks behave like the poles of magnets and repel each other, then you should find an article directly showing it, an article that implies it, or perhaps conduct your own research.
