One family member's mood and behavior influence the others. System thinking goes beyond blaming others to seeing how things are for the whole group. All systems have characteristics of being open systems or closed ones. Systems can be placed on a continuum from open to closed. Most family systems fall somewhere in the middle between open and closed.
Systems vary from time to time in their ability to be open and closed.
When more stressors come down on the system, they become more closed and rigid. The quality of life in your family, job or spiritual group system is generally based on the overall mental health of the most dominant member. Certain behaviors and attitudes in system members make a system open. People are treated with love, respect and caring in open systems. Their needs are acknowledged.
