White guilt might be one explanation, but there are others. It could be that the advertisers are pandering to the negro community by vastly exaggerating documented levels of negro intelligence. It might also be that advertisers are so afraid of the professional racialists such as Jesse Jackson, Al Sharpton and their associated organizations that they are so careful not to portray a negro in an inferior light that they go to extreme measures to show the negro as intellectually superior beings, contradicting what we all know to be true.
