  2. Use language that is neutral and does not have any negative or positive connotations that might the listener or reader assume you have a bias
  3. Use evidence and data to back up your claim from reputable sources and not just your own personal opinion

  • Skills to prevent conflicts and promote buy-ins
  1. You need to know how to listen in order to communicate effectively, pay attention to how other people respond to what you say so you can either apologize for your behavior or look out for in the future. Listening also shows that you value the other person's opinion and thus might make them more likely to treat you with the same respect
  2. Encourage other people to buy into your ideas by being confident about them and again using evidence so that people can trust what you're saying has some merit to it.
