I could say the same for you. You have provided ZERO, nadda, zilch evidence. You only provide "article" that do the thinking for you. I on the other hand do not simply take someones word for something. I look at the data. You haven't done that, and I suspect you have no specific training in statistical analysis, which is ok, but it also explains why you're unable to offer up any opinion of your own concerning the study. Instead opting to quote the opinions of others. Statistical data, only at best gives us the ability to form conclusions based on correlative value, not causative. They can sometimes lead to the truth, but by themselves they are NOT the truth. Do you understand that concept, Redress? Statistical analysis of data sets, and variables lead us in the right direction. In other words, it tells us where we should look next.
If you don't understand that, I can't help you. You haven't provided evidence of any truth, nor have I, because there isn't any truth yet on the subject.
Let me give you an example. (And I swear I have no idea why I'm wasting my time with educating you). IN your 2010 study, I already know that seeing the data is extremely important based on what you had quoted. Know why? Because the variable used for the test scores is missing. It only says that similarly situated heterosexual parents, and children of the same age were used. It gives no other data, no variables, no screening methods, nothing.. It doesn't say ANYTHING that would suffice as evidence.
Now, do you have the study or should I go look for it myself?
