preferences. As we mentioned in section 3.2, based on the expert judgments, we weighted
different information sources by their degree of enrichment and quality of information.

continuous variable and regarded it as independent variable. We made a correlation analysis
of the variable related to information source horizon and different gender, age, income,
educational level and occupation (Table 2).
