  Society is showing signs of strong ideological polarization. When pushed to
seek perspectives different from their own, people often reject diverse ideas
or find them unfathomable. Work has shown that framing controversial issues
using the values of the audience can improve reception of opposing views. In
this paper, we present Pano, an interactive system motivated by moral framing
theory that educates news consumers to think in a framework of fundamental
human values. Pano encourages users to challenge their understanding of
opposing views through collaborative annotation and discussion of moral framing
in articles and comments. We describe two iterations of Pano -- the first
covering a suite of ways to interact with news, and the second tailored toward
annotation and discussion. We find that compared to a control, Pano users more
often empathize with and re-frame arguments in the moral values of the opposing
side, showing promise toward the ultimate goal of bridging the ideological
divide.
