Something I find interesting is how utterly different society was a mere fifty years ago. One of the great failures of most SF is that it assumes the world of the future will be technologically different, but that society’s attitudes will be more or less the same as ours. Maybe that’s because we want to believe that we are enlightened and superior beings—we don’t like the idea that in fifty years, people will look back at our worldview and say “What a bunch of bigoted little troglodytes.”
Not all the advice in the linked article is bad, mind you; #9 is worth noting. Men do seem more able to distinguish between “That’s a really dumb idea you just suggested” and “You must be really dumb to have suggested an idea like that”. I once spent a frustrating time trying to convince my ex- that those two statements really weren’t equivalent.
