I'd like to place the blame on the level of pollutants in the world, they transfer to the fetus, and it doesn't develop well, but that can't take the blame, because statistics show that I.Q.'s are on a rise and child development is better than ever. so i blame it on laziness. all the tards out there who refuse to even bother knowing anything useful, or using their minds for some sort of constructive purpose, because it's simply easier not to. the "why read a book when i can watch the movie" attitude.

now to find the source of the laziness.

of course that doesn't explain the lack of common sense, which is now uncommon sense. i have no explanation for that.
