Figure 1

An example false post. The example is from a source-credibility condition (i.e., credibility information is provided for both the post source [27 out of 100] and the participant [71 out of 100]); the participant’s response in this case was to flag the post; information on the dynamic changes (“ + 1” increasing follower number from 21 to 22; “ + 2” increasing credibility from 69 to 71) was only displayed briefly. In the example, the first comment represents a strong refutation; the second comment is a weak refutation.
