After answering the above questions and seeing the responses from your classmates, think about how you responded. Did this differ from how your classmates responded? Try to give reasons for how you chose your responses to the above questions. Ask classmates for their reasons for responding as they did. It can be particularly useful to share your answers with someone who chose a different response from you. You can summarize the various reasons for volunteering and not volunteering in the activities below.
Activity 4.5.2. Volunteer or not.
After answering the questions, were you likely to volunteer or unlikely to volunteer? For example, were you likely to be the one to call the power company or get eaten by sharks, or were you generally hoping someone else would do it? If it depended on the situation, explain under what circumstances you were likely to volunteer.
Activity 4.5.3. Always a volunteer.
After sharing your answers as a class, did each situation have a volunteer? In other words, was there always someone willing to call the power company or take fewer points? If there was a question with no volunteer, can you suggest why?
Activity 4.5.4. Unlikely to volunteer.
For which questions was it unlikely that there would be very many volunteers? Did you take that into consideration when deciding if you were going to volunteer?
Activity 4.5.5. Reasons to volunteer.
What are some reasons for volunteering? What are some reasons for not to volunteer?

4.
Although our experiment did not change the number of participants, think about what you predict would happen if we now played this experiment with the entire school or community. As the number of participants goes up, it becomes likely that there is a volunteer.
more
Generally, if there are more people, we can predict that there will be someone who volunteers.
less
Generally, if there are more people, we can predict that there will be someone who volunteers.
5.
Although our experiment did not change the number of participants, think about what you predict would happen if we now played this experiment with the entire school or community. As the number of participants goes up, it becomes likely that any specific individual volunteers.
more
Generally, if there are more people, there is less pressure on any one person to volunteer. People are more likely to let someone else volunteer.
less
Generally, if there are more people, there is less pressure on any one person to volunteer. People are more likely to let someone else volunteer.
6.
True or False: In trying to get the best outcome for yourself in this experiment, it is useful to consider how likely it is that other people volunteer.
True.
For example, if you think there are likely to be other volunteers, you may not to volunteer. You can get the benefit without the cost of volunteering.
False.
