In a good faith contract, how do the parties involved behave?

In a good faith contract, the parties involved behave with honesty and fairness towards each other. The essence of good faith in contract performance means that each party is expected to cooperate and uphold their obligations while also considering the interests of the other party. This leads to a more flexible interaction, where parties may adjust their behaviors to accommodate the contract's spirit, even if they are changing independently.

This independent adjustment doesn't imply that one party can act arbitrarily or in bad faith; rather, it suggests that each party has the freedom to adapt their actions as necessary while still honoring the underlying agreement that binds them. Good faith fosters an environment where parties can work towards a mutual understanding, maintaining the integrity of the contract without being restricted solely to rigid interpretations of the written terms.

The other options suggest behaviors that are not aligned with the concept of good faith. Acting based on public interest or through collective negotiations implies a level of intervention that may not be necessary in every good faith situation. Similarly, being bound by written agreements to change indicates inflexibility, which contrasts with the more cooperative and responsive nature expected in good faith dealings.
