1) The document describes an activity called "Mouse Trap" where participants had to arm and disarm a mouse trap either alone, while blindfolded with help from someone trusted, or while blindfolded with help from a stranger.
2) Discussing the activity led the group to realize that it is difficult to trust strangers because you don't know them well, but that there is also a chance of being let down by people you know.
3) The group then had an insight that instead of making people "earn" trust, a better approach is to start by "giving" trust to others without waiting for them to prove themselves worthy.
