The medium is the means

IN THIS fast-paced world, we seldom have time for face-to-face meetings. You are just as likely to conduct your personal and business negotiations by email, or some other electronic medium, as you are in person. How does this impact your powers of persuasion?

The question intrigued Rosanna Guadagno of the University of Alabama and Robert Cialdini of Arizona State University, who have been comparing the persuasive power of online communication with face-to-face meetings.

In a study published in 2002, Guadagno and Cialdini had a group of students discuss the introduction of new exams (Group Dynamics: Theory, Research and Practice, vol 6, p 38). The group was split into same-sex couples. Unbeknown to the subjects, each pair included an accomplice of the experimenters whose role was to provide arguments in favour of the idea. Half the discussions took place in an online chatroom, the other half sat face-to-face.

While overall men rated the proposals similarly whether they participated in the electronic or face-to-face sessions, women in face-to-face sessions rated them more highly than those who only took part online. Guadagno and Cialdini suggest this is because groups of women tend to form communal bonds and reach agreement. Electronic communication disrupts the exchange of social cues women use to establish a communal bond and is therefore less conducive to persuasion.

On the other hand, groups of men typically try to establish their competence and independence, which can lead to competitive encounters. When two men who have not met before debate a point, online interaction is about as effective and persuasive as face-to-face.

But if they have met and had a competitive exchange, subsequent face-to-face meetings are less productive, whereas online exchanges fare far better. So while online communication can prevent women "connecting", it can help men suppress competitive urges that hamper persuasion.

So, if you're a woman and want to persuade other women you'd be better off meeting face-to-face, while men are less confrontational if contacted by email. The researchers are now studying these effects in mixed couples.
