Regarding gender differences in conversation style, Tannen draws bold conclusions which seem to get at what men and women want out of conversation, how they approach the world, and so on. For example:
I now see that my husband was simply approaching the world as many men do: as a place where people try to achieve and maintain status. I, on the other hand, was approaching the world as many women do: as a network of connections seeking support and consensus. (Tannen)
I often see the conclusions talked up with little evidence discussed. As far as evidence goes, when talking about Tannen's views in their respective textbooks, Trudgill brings up frequency of use of indirectness and of interruptions and Iwata et al. bring up frequency of jokes and of taking the floor in conversation. Surely there must be more evidence to back up the bold conclusions.
Question: What empirical evidence does Tannen offer for her conclusions regarding men and women's different approaches to conversation and the world?
