how can one avoid having problems communicating with his group?

The book "The Essential Guide to Group Communication" written by Dan O'Hair and Mary O. Wiemann mentions a very important concept to help improve the communication between a group and its member. The concept I chose to talk about explains how to avoid misunderstandings and problems in between group members. As the book explains, there are four things one can do in order to prevent any communication problems from occurring between himself and his group members. First off it says that it is important for people to be able to communicate with one another without feeling attacked. It is important to trust one's group members of course, but it is also important to discuss arguments and ideas in order to avoid misunderstandings or lack of communication later on. The second point made is to avoid making an issue more simple. Some people tend to want to avoid the issue completely and tend to want to make it more simple to avoid any kind of confrontation which is not good. It is important to discuss an issue fully and it is better to argue about it (in a polite manner) instead of settling for something that will later on cause an issue. My experience this summer is a perfect example to show that making an issue more simple does not work. This summer, my friends and I decided to take a road trip to Los Angeles. We had agreed that we would go to Disneyland, visit the Honda Center, attend some sporting events, etc. When the time came to discuss money issues and traveling plans, one of my friends told us to do as we pleased as she did not want to get involved in the planning. When we got to LA however, she complained that the trip was costing her too much money and that we should have gone to more places she wanted to go to. Had she participated in the planning of the trip with us instead of trying to make the issue more simple, she could have enjoyed the trip as much as we did.
Another point made, is that it is important not to overgeneralize an issue. it is very easy for people to sometimes assume that their facts are always true. For example, assuming that all American teenagers have children before the age of 18 is completely untrue and is called overgeneralizing. It is therefore very important not to do that and to make sure that one's point is actually based on actual facts and data. Lastly, it says to avoid making false assumptions. False assumptions tend to happen when there is a lack of communication between people; it is therefore important for people to keep all communications open and keep an open mind while discussing an issue.
I chose to talk about this specific concept the book brought up because I found it to be really important. It is really easy to lack communication in a group and these four points are great points to avoid this issue from happening between group members.
