Many of us are inclined to share more than we actually do. But the opportunity to know what others need seldom presents itself. Sometimes we find out by chance. Can I borrow your ladder? In addition to the limited opportunities, we also harbor valid concerns. What if it breaks or gets misplaced? These concerns vary depending on who's involved and the information or object shared.
Sharing among neighbors is interesting because some of the necessary ingredients are in place (proximity and goodwill) and the benefits are great (convenience and reciprocity). Yet there is still a high hurdle to get over. The risks seem more immediate and tangible than the benefits. We say to ourselves, "if I share, I know what I might lose, but I don't yet know what I might gain." However, if everyone starts sharing, we start looking at the situation differently, and say "I see what I can borrow, so what do I have to lose?"
In micro-economics, collective action dilemmas explain why a group's efforts to take action often fail, despite the motivations and good intentions of its organizers. At rBlock, we have designed the first share engine to help a group of neighbors on a block share information that will help them to prepare for any kind of emergency, be it an accident, a medical problem or a natural disaster.
