genetic interpretations of MZ/DZ differences are premised on the assumption that the environments of MZ’s are no more similar than those of DZ’s - that assumption is false, so the heritability (49%) is shared environment

Wrong. That assumption has been tested several times and is valid. https://www.sciencedirect.com/science/article/pii/S0049089X13001397 … https://link.springer.com/article/10.1007/BF01067551 … https://idp.springer.com/authorize/casa?redirect_uri=https://link.springer.com/article/10.1007/s10519-013-9602-1&casa_token=aQuccrI2zgYAAAAA:qeSMSVjpX8ie2KithSwN6bbUa8xo4KRmCoUBMiBP_iJst7ifn7Qf2YdKIdZq1LRdGOcwZ0F1l8hWnino1w … https://link.springer.com/article/10.1023/A:1026549417364 …

Thanks
@salonium — I hadn’t had a chance to get links together to respond yet! -
No worries! I had some saved because I wrote an essay on twin study assumptions earlier this year
-
Is it published somewhere?
-
Nope.

A sceptical analysis of that study. Or maybe more the larger context of metastudies, what heritability means etc.. I think is quite goodhttps://scientiasalon.wordpress.com/2015/06/01/heritability-a-handy-guide-to-what-it-means-what-it-doesnt-mean-and-that-giant-meta-analysis-of-twin-studies/amp/?__twitter_impression=true …
