You know what they say about assumptions right? Stop making an ass of yourself.

What do you even think "smart" means?

I know what it means. If you don't then go look it up.

Did you know that amazing innovative inventions are made my children in impoverished third world countries that drastically change the daily lives of those around them? Are they not "smart" because their families are poor and don't use contraceptives?

First wrong assumption.

Were my parents not "smart" because instead of spending their free time making money or paying universities or expensive hobbies they instead chose to dedicate their time to the kids they accidentally started having at 16?

Second wrong assumption.

Are you saying that anyone who has more children than you have apparently deemed appropriate is by default a "stupid" person, since you seem to believe smart people don't have as many kids.

Third wrong assumption.

Your comprehension of the definition of smart would seem to by default include not having lots of children.

Fourth wrong assumption.

You also seem to think that having more money per person is the ideal for betterment of humanity. That in itself is pretty telling.

Fifth wrong assumption.

You managed to wrongly assume five different things from me typing two questions. And you managed to answer neither of them. I'm not going to bother trying to explain how intelligent people have, on average, fewer children. It's really not a complicated idea but you managed to miss it entirely.
