Abstract

This study used choice experiments of different variable ranges to investigate the optimal number of variables to be used in choice experiments. Too many variables for a choice experiment can increase participants’ cognitive load to the point that it becomes a burden, leading them to make choices that aren’t in line with their actual beliefs. Choice experiments allow researchers to assess participants’ preferences regarding mining projects in their community. An online-based tool called Qualtrics was used to collect data. Results indicate that participants exerted more mental effort as the number of variables increased. They rated each level as significantly more difficult than the previous level. There is evidence that four variables is the optimal number of variables to use in choice experiments. These results suggest that mining communities using choice experiments for community consultation should be aware of the demands of cognitive load and limit choice experiments to four variables.

Biography

Jordan Verslues is a senior in Mining Engineering at Missouri University of Science and Technology. As a current member of the Missouri University of Science and Technology Mine Rescue Team, he is knowledgeable of the hazards and inner workings of mining operations. The mine rescue competitions require team members to collaboratively research and solve the simulated mine disaster problems during the competition. He is also enrolled in the Army ROTC program and understands the importance of healthy interactions between people.
