“College sophomores may not be people,” (Carl Hovland quoting Tolman) yet research done on them continues to be a significant part of all research in Social Science. The status quo is a function, not of want, but of cost, and effort.
In 2007, Cindy Kam, proposed using university staff as one way to move beyond the ‘narrow database’.
There exist two other convenient ways of expanding the database further – alumni, and local community colleges. Using social networks, universities can tap into interested student, and staff acquaintances.
A common (university wide) platform to recruit, and manage panels of such respondents would not only yield greater quality control, convenience, but also cost savings.
