I agree with the statement that intelligence is closely related to communication. I feel that's something younger people, myself included, often forget to think about. You can be the smartest person in the world, but if you can't put it into words and therefore fail to share your thoughts with others, you won't be perceived as such. Mastery of spelling, grammar and vocabulery are necessary for people to take a text serious. It all starts with language, and I think we need to focus on that aspect of intelligence a bit more again as a society (I can only speak for what I see happening in Belgium and that's a reduced knowledge and worsening application of the Dutch language in my opinion. Do you guys experience the same in other countries?)
