Af. Hayes et al., Willingness to express one's opinion in a realistic situation as a function of perceived support for that opinion, INT J PUB O, 13(1), 2001, pp. 45-58
We examined how people's willingness to speak their opinions in a real situ
ation varied as a function of perceived support for those opinions. When gi
ven a list of six potential topics to discuss with a real group of people,
the participants reported a greater willingness to discuss a topic if they
perceived greater support for their own opinions on that topic. The relatio
nship we observed was much larger than the average correlation reported in
a recent meta-analysis (Glynn, Hayes, and Shanahan I997). Methodological an
d psychological explanations for the discrepancy are discussed.
