Fritz Strack

Strack's study asked participants to hold a pen in their mouths in such a way as to make them either smile or frown, and then had them rate how funny a series of the Far Side cartoons were. In this study, participants who were smiling rated the cartoons as funnier, on average, compared to those who were frowning.^[5] In 2016, a study by a separate research team was published which failed to replicate the original study's results.^[6][7] Strack himself suggested^[8] that the negative results of the replication study may have been caused by its researchers' use of a video camera to record the participants' responses. He also took issue with the replication study's choice of the same cartoons that had originally been used in 1985.^[9] Subsequent research has supported Strack's claim that participants knowing they are being recorded by cameras led to the replication study's negative result.^[10][11] Further evidence has provided additional support for both the pen procedure and the validity of the facial-feedback hypothesis.^[12][13]
