Judith C. Waller said this quote

Advertisers as well as political leaders long ago found that it is easier to appeal to the people through the heart than through the mind. Programs built with an emotional people are sure to draw the largest audiences and the biggest response. Workers in the field of educational radio are loath to acknowledge this truism, maintaining that certain programs must be built to appeal to the intellect. Of course, they are right, but that is the minority appeal.
