So-called twin studies ought to be understood in the first place to be faulty. First of all, all human growth begins from a single cell which then divides and then each of those cells divide and so on. Obviously, our cells are different and produce amazing and unique organisms, structures and all the different parts which make us individuals. It was assumed that identical twins had “exactly the same genes”, as you referred to it. However, that isn’t quite true. While they might share common genes, there are still differences in their genetic make-up which are significant enough to not only identify them as individuals but also to ascribe a wide range of differences from one twin to the other.

As twins continue to grow separately from one another, even conjoined twins, the same principle applies, of them continuing to grow separate, unique and further influenced and impacted by the deviations and environmental considerations of their specific life. One twin could suffer from genetic linked syndromes while the other might not. Research has shown that identical twins can have different numbers of copies of each gene. Also our DNA can change as we grow and can be affected by different factors. It’s irresponsible to assume that just because two people came from a single egg to begin with that they are exactly the same.

That’s the issue I have with all so-called scientific studies. They become so narrow-focused that they forget about the most basic principles which in my opinion should be obvious. Instead, they assume fictitious conditions devoid of anomolies which they know to be true but have tossed aside because they are inconvenient for them to use in research. In other words, if the study couldn’t be conducted without using twins, then it’s possible that there’s a bias and it wouldn’t hold up when the findings were applied to the general public.

Medical research removes conditions from the pool of test subjects so that, in the researcher’s minds, they can have a more focused study. But in doing so, they have just thrown out very real factors which do occur as adverse conditions and which cannot be ignored just to make things easier. It’s alright to remove them in preliminary studies to help try to figure out an answer. But in order to verify that a true solution has been found these removed conditions absolutely must be returned to the study and be added in with the larger group to be retested. If the same results occur as previously, then the work is done.
