Judgmental confidence 
On the basis of a one-way ANOVA with the pre-decisional disposition as the independent variable and the 
difference score between pre-decisional judgmental confidence and post-decisional judgmental confidence as the 
dependent variable (F(2, 270) = 11.12, p<0.001), simple comparisons were performed by a two-tailed least 
significant difference test. As predicted, respondents with no established pre-decisional disposition showed greater 
increase of post-decisional judgmental confidence than the respondents with an established pre-decisional 
disposition of “leaning toward booking the hotel” (

the “leaning against” group, the direction of the increase in post-decisional judgmental confidence in the 
“undecided” group was as predicted but the difference in increase failed to achieve conventional statistical 
significance (
