My point was that the educational system has been tweaked to be easier for everyone across the board. Children that previously performed better still perform well, children that performed worse now perform better than before. I'm not rejecting that contraception could be a reason, it's just that you have to show convincing evidence for it. The more counter intuitive your theory is the more evidence you need to produce. Imagine I declared that all of this is correlating with the size of Big Mac menus and has nothing to do with changes in the educational system. It wouldn't be unreasonable for you to question my theory, especially if I do not provide any evidence. > Not sure why people feel a need to downvote things they don't agree with I have no problem with that. If I'm just regurgitating what everyone is already believing then my comments would be pointless. I happen to have a different opinion and I know that for some this is offending. (but thats really their problem, not mine)
