Harold Garfinkel made a name for himself as a sociologist by changing certain aspects of a social situation and seeing what the consequences would be. In this way, he was able to identify implicit social rules by breaking them. This process became known as Garfinkeling. An example would be to change the gender of a person in a certain situation (in order to highlight the gender role assumptions being made) and seeing what difference that makes. Changing age group can also be enlightening in terms of highlighting ageist assumptions. For example, I once came across a geriatrician who would challenge ageist statements by saying: ‘Would you have made that comment if this person had been 30 years younger?’. Garfinkeling, then, is a useful tool for highlighting discriminatory assumptions by reversing some aspect of the situation so that previously taken-for-granted assumptions become apparent. Try it. It can be fun as well as enlightening.
