Final answer:
Problem solving is most effective in an atmosphere of personal involvement, responsibility, purpose, and belonging, as it fosters collaboration and mutual support.
Step-by-step explanation:
According to the authors of FFYM, problem solving is easiest when couples have created an atmosphere conducive to a sense of personal involvement, purpose, belonging, responsibility, challenge, comradeship, and love. This suggests an environment and lifestyle that encourages mutual understanding and support among partners. When facing coordination problems that inherently come with various transaction and conformity costs, it's vital that people of good faith collaborate effectively to overcome these challenges. Creating such an environment helps in reducing existential threats and promotes the successful resolution of issues.
