Brad, since you mentioned the risk of sounding like a broken record, I understand you belong to the camp of non-believers (just using your term, hoping this way you can understand better), and I will take this risk for once more. Whether it is for my amusements, or for trying to prove an already very evident point I will leave this with you (certainly if you would bother to). I propose for all the non-believers a very simple exercise. Tossing a dice can result in only 6 outcomes. Just give it a try to find any bias tossing a common dice 1000 times, or 10000 times. It is something worthy to do because this way one can understand how the “bias” works in a very, very simple case compared to the gigantic almost 14 million outcome case of 6/49 lottery. After that, if, and I am emphasizing if, anybody would be able to improve the odds of predicting the dice outcome, the first step in understanding how the bias in a 6/49 lottery works can be considered as achieved.
There is one more point, which is not clear for me. When you say “bias”, do you mean something that is inserted intentionally by the lotto corporation (s), or do you mean a natural, spontaneous and uncontrollable bias strictly related to the non-perfect apparatus that is used to draw the lottery. This is important, because, though the result would be the same (the impossibility to predict the lotto outcomes even knowing what the bias is) the statistical explanation would be different.
If being a non-believer and thinking and hoping that somewhere, sometime, somebody will handle the so called bias, works like a joint of pot, I am very sorry to have disturbed the whole camp of non-believers, although as you Brad say: “…most likely won't listen to someone who tells them they know better ...”
PS To avoid any confusion, "non-believer" is somebody who thinks that there is a bias in the lotto draws, according to Brad terminology used in the previous post
