Peer pressure can serve good causes

Bad ideas will consolidate if they circulate inside a group of people. Individuals will fear losing their membership in their group. An idea does not stand for itself. The identity of the person plays a big role in keeping a specific idea at the center. If you would overthink this idea from a neutral standpoint, you would probably come to a different conclusion after some time has passed. But because other people repeat the same points, you keep on believing.

You don't want to sacrifice things or leave your community behind. You want to belong. And you don't want to get shamed for stating something that is contrary to the group's beliefs, because that risks rejection or exclusion from the group.

But the same is also true for good ideas that are worth keeping at the center. It is helpful to have people around you who could potentially look down on you or shame you for changing your opinion or dropping your activities towards a good cause. Good ideas can be hard to follow through. In moments of weakness, we question why we should even try. Examples that come to mind include being vegan, refusing the use of technology from shady businesses, and avoiding products that cause harm. Discipline is needed. A good community around you is definitely helpful. But with no one to judge you it is easier to make exceptions to the rules you have set for yourself. These are rules that align with your beliefs. These rules are worth upholding.

Even if your community or friends do not actually shame you for dropping a good idea, the fact that you think they will does support the upkeep of good values. The fear of rejection can protect your ethical commitment.
