Edwards published more than one hundred journal articles and books, including, Decision Analysis and Behavioral Research and Utility Theories: Measurement and Applications. In the introduction to a festschrift for Edwards, Barbara Mellers states,
- Decision Science and Technology is a compilation of chapters written in honor of a remarkable man, Ward Edwards. Among Ward's many contributions are two significant accomplishments, either of which would have been enough for a very distinguished career. First, Ward is the founder of behavioral decision theory. This interdisciplinary discipline addresses the question of how people actually confront decisions, as opposed to the question of how they should make decisions. Second, Ward laid the groundwork for sound normative systems by noticing which tasks humans can do well and which tasks computers should perform.
In 1962, Edwards founded the Bayesian Research Conference with the aim to incorporate and apply Bayesian statistical methods and ideas to decision theory. This conference was renamed the "Edwards Bayesian Research Conference," in his honor, in 2005. In the field of statistics, he is well known as lead author of the review article "Bayesian Statistical Inference for Psychological Research," which introduced the notion of 'stable estimation,' and was the first to note that a p-value of 0.05 in the normal linear model corresponded to a lower bound on the Bayes factor of 0.26.
