Additional message strategies will be investigated (gain vs. loss, and process vs. outcome framing) in order to understand what type of messaging will result in the highest portfolio risk scores, and how portfolio risk mitigating strategies can be developed. An advanced metric for calculating portfolio risk known as the Risk Index Factor (RIF) is developed, which is the primary dependent variable of both Study 1 and 2. Two experiments will be conducted, separated into two studies. Practical and theoretical implications of anticipated results of the studies are discussed.
