Description
Details
of Study : Researchers wanted to test whether people’s
support for animal rights activists would be influenced by the extremity of the
activists’ behaviors. In an experiment, participants were randomly assigned to
read one of two fake news reports (variable = condition) that differed in the
extremity of the activists behavior. Specifically, participants read about a
made up animal rights group that engaged in protest behavior that researchers
considered to be Moderate (the activists picketed outside a cosmetic company’s
building) or Extreme (the activists broke into and vandalized the building and
freed the animals held inside).
After reading the fake news article,
participants answered questions about 1) how extreme they thought the activist
group was, and 2) four items to measure their support of the activist group.[1]

Condition |
A categorical variable with two levels that describes which version of
the news article participants read before making their ratings of the group. ●
Moderate : the
activists picketed outside a cosmetic company’s building ●
Extreme : the
activists snuck into the building, vandalized the building, and freed the
animals held inside |
