 Distinguishing decision‐making phases

Decision‐making phases	Description	Measurement elements
Deliberation	1. Information search 2. Knowledge gain 3. Appraisal of knowledge sufficiency 4. Imagining counterfactuals 5. Affective forecasting 6. Preference construction	Perceived sufficiency of information gain, knowledge gain, perceived clarity about the nature, loss and gain of counterfactuals based on preference construction.
