The purpose of the present study was to test the effectiveness of three different types of appeals in changing participants’ perceptions willingness and likelihood to consume MSG, a commonly stigmatized food ingredient. The rational appeals (2 MSG Facts and 4 MSG Facts) were selected as corrective strategies because existing research shows factual information facilitates the correction of misperceptions when cognitive processing is employed ( Schwarz et al., 2007). Findings from the present study reinforce that rational appeals are more effective than emotional appeals in increasing willingness and likelihood of consuming MSG, a commonly stigmatized ingredient.
