Type of estimate	Instruction
Intuition	Please do not think deliberately. Answer quickly what comes to mind intuitively. Please answer within 8 s.
Deliberation	Please ignore your intuition. Think deliberately before answering. Utilize your knowledge and experience, while being aware of the basis of the estimate. There is no time limit. Please use enough time to think about the following question.
Dialectic	First, assume that your last estimate is off the mark. Second, think about a few reasons why that could be. Which assumptions and considerations could have been wrong? Third, what do these new considerations imply? Was the second estimate too high or too low? Fourth, based on this new perspective, make an alternative estimate. (The computer display shows the second estimate).
General crowd’s perspective	How do you think people, in general, estimate the following question? Think and answer how people, in general, estimate this. Please do not answer you own estimate.
Disagree-other’s perspective	Now, picture a friend whose views and opinions are very different from yours. To illustrate, when discussing politics, societies, and daily affairs, you often find yourself disagreeing on various issues. How would he or she answer the following six questions? Answer these questions now as this friend. Please do not answer your own estimates.
