Abstract:
... The gap between people’s attitude and action as regards environmental issues has been pointed out even while surveys registered an increase in people’s environmental awareness. Among the possible reasons is that people tend to automatically answer “yes”, as most surveys on environmental consciousness use positively-phrased questions or prompts. To remove the “yes-bias” in previous surveys, this pr ...
