Final answer:
The win-win conflict-handling method is problem solving, which seeks solutions benefiting all parties. It is distinct from, and often more effective than, compromise, where each side sacrifices some of their goals.
Step-by-step explanation:
The conflict-handling method best described as win-win is d. problem solving. This approach involves friendly interactions and open dialogue, where all parties work collaboratively to find a solution that satisfies everyone's interests to the greatest extent possible. It contrasts with methods such as avoiding, accommodating, or compromising, where there may not be a mutually beneficial outcome. Problem solving aims to go beyond compromise by not just splitting differences but by generating new solutions that can provide a win-win scenario.
In collective decision-making, there is often a bias toward b. majority rules, which means the decision tends to follow the preference of the majority of the participants. However, when participants generally agree on goals but have minor disagreements, compromise becomes a likely outcome. Compromise is not ideal as a win-win approach since each party gives up part of what they want, but it may still result in an agreement.
