  The effect of user bias in fact-checking has not been explored extensively
from a user-experience perspective. We estimate the user bias as a function of
the user's perceived reputation of the news sources (e.g., a user with liberal
beliefs may tend to trust liberal sources). We build an interface to
communicate the role of estimated user bias in the context of a fact-checking
task. We also explore the utility of helping users visualize their detected
level of bias. 80% of the users of our system find that the presence of an
indicator for user bias is useful in judging the veracity of a political claim.
