A volunteer group noticed that members who shared small uncertainties early often built trust. Others could respond before a minor problem grew, so honest sharing sometimes led to stronger cooperation. The group also observed a second direction. Once trust had formed, members became more willing to share incomplete ideas that they would previously have hidden. These claims did not cancel each other. The first described how early sharing could help create trust; the second described how existing trust could encourage further sharing. Neither direction was guaranteed. The words often and could limited the strength of the claims, and once marked the time order. A reader who recorded only the repeated words sharing and trust might miss both the reversal of direction and the change in conditions. A better note used two arrows, each with its own starting point, result, and limit.
