People need information in order to make effective choices and to feel
competent in managing their own affairs. Decision-making research pro
vides tools for identifying and addressing these informational needs.
The tools allow formal analyses of what information is critical to par
ticular decisions, as well as descriptive analyses of how well those f
acts are understood. Communication should be focused on critical infor
mation that is either missing or available but not understood. Decisio
n-relevant situations range from ones posing well-formulated, imminent
choices to ones in which people are trying to understand what choices
are even possible. This article reviews briefly the formal and descri
ptive approaches to dealing with such decisions. Including these appro
aches in behavioral interventions might help people to be as systemati
c as they would like in their decision making. It might even make them
want to be more systematic.
