Or, after committing crime do you think you might decide to treat yourself to a cone?

This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships.

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally.
