Men and women speak different languages, shows study

New research finds how power dynamics shape the speech of men and women.

Surprising Science
  • A new psychology study finds differences in speech patterns between men and women.
  • Men tend to use more abstract language, while women focus more on the details.
  • This tendency is due to power dynamics that can be changed, concluded the researchers.
