People generally go in, not really believing that they will match. They think it only happens to others. Their attitude usually changes when this abstract possibility becomes a tangible reality. Before taking the test: "Ah! I probably won't even be a match. Why bother?" After being matched: "Shit! Is this for real? A life now depends on ME?" There's a similar phenomenon when a competitor starts winning and the possibility of him actually becoming champion materializes. Believers come out of the woodwork. That's why the goal isn't to convince them to give bone marrow, but rather to just see if they match first.
