Pro-environmental behaviors correlate with delay discounting
A total of 138 participants were recruited via Amazon Mechanical Turk to evaluate the relationship between temporal discounting and pro-environmental behavior. Pro-environmental behavior was assessed by using a modified version of Whitmarsh and O'Neill survey. Temporal discounting was assessed by Kirby's 27-item delay-discounting measure. The results showed a positive trend correlation between pro-environmental behavior and temporal discounting; i.e. the more discounting of the future was correlated with less pro-environmental behavior. This trend became much more significant when we just analyzed those participants who answered "Yes" to the question "Do you think climate change is something that is affecting or is going to affect you, personally?" to which 98 out of 138 participants of our study answered "yes". For this upper %70 of participants the Pearson correlation coefficient was r = 0.28; p = 0.006. We also analyzed different demographic traits to see whether there is any difference between sub-groups regarding differential pro-environmental behaviors. Two features turned out to be highly predictive of the pro-environmental behavior: education and marriage. Married and higher educated tend to act more pro-environmentally than single and lower educated.
