I would say that as you ride more often in groups, you get better at it, and you get more confident and steady yourself, but just because you are a steady, trustworthy rider does not mean that the rider in front of you is. What happens--in my experience--is that it becomes easier to quickly pick out which riders are good to ride behind, and which ones you want to avoid being near.

If you are lucky enough to have a small group of friends to ride with on a regular basis, you can practice your group-riding skills there before trying a group of people that you don't know. In both cases, though, a large amount of trust is required, and I guess the trusting does come more easily the more you do it.
