Provocative premise of familial genetics influencing field of study - PLoS ONE article

It took me a few steps to get to the original source in the PLoS ONE online publication,
but along the way the "headlines" in the social media and mainstream caught my attention with 
their own (over)statments;

in any case, this article should be sure to generate dialogue and discussion >>>>

so here is the title in PLoS ONE:

"Familial Linkage between Neuropsychiatric Disorder and Intellectual Interests" 
http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030405

and then the other interpretations:

"Grandma's mental health may have shaped your interests" = http://goo.gl/MnpOQ

and this commentary in the NY Times:

"College Major and Family Mental Illness"  = http://goo.gl/XntQI

What intrigues me is the methodology and the statistical accounting in the PLoS ONE article, and
the implications for ASD and the supposed connection with STEM academic areas, but it also
raises the notion of CP Snow's " Two Cultures" (again ?) - see Scientific American article = 
http://www.scientificamerican.com/article.cfm?id=an-update-on-cp-snows-two-cultures

but at another level it also reminds me of the way in which "headlines" are generated 
from the original source - and then "creatively" organized in a slightly different statement as
it unfolds from primary to secondary and then to ripples outward with signal to noise ratio
affected - and the specificity of information suffering from degree-of-separation decay.
