Here’s an interesting article on the psychology of communication:
Our intuitive understanding is that face-to-face communication is the most persuasive. In reality, of course, it’s not always possible to meet in person, so email wins out. How, then, do people react to persuasion attempts over email? Persuasion research has uncovered fascinating effects: that men seem more responsive to email because it bypasses their competitive tendencies (Guadagno & Cialdini, 2002). Women, however, may respond better in face-to-face encounters because they are more ‘relationship-minded’. But is this finding just a gender stereotype?
I wonder if there’s any material difference between email and blog comment forum discussions?
