Reference excerpt

Ward Edwards (1927–2005) was an American psychologist, who is prominent for work on decision theory and formulation and revision of beliefs.

Biography

Childhood Edwards was born on April 5, 1927 in Morristown, New Jersey. His family moved twice during his childhood first to Woodbury, Connecticut, and then to Washington D.C. Edwards' father, Corwin D. Edwards was an economist.

Education and career After serving in the U.S. Navy from 1945-1946, Edwards earned his BA in psychology from Swarthmore College in 1947. Edward earned both an M.A. in psychology (1950) and a PhD in psychology (1952) from Harvard University. Edwards' major interests in graduate school were psychophysics which later became known as experimental psychology, and probability. Following his time at the University of Michigan, Edwards came to the University of Southern California in 1973.

Awards Frank P. Ramsey Award from the Decision Analysis Society, 1988 Distinguished Scientific Contributions Award in Applied Psychology, American Psychological Association 1996 2004 class of Fellows of the Institute for Operations Research and the Management Sciences "The Association for Psychological Science named Ward Edwards as a James McKeen Cattell Fellow in recognition of his sustained and seminal contributions to the technology of decision making and to behavioral decision theory", James McKeen Cattell Fellow Award, 1995.

Research 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.

Worked examples

Example 1 — a first encounter with Ward Edwards

Start with the simplest possible case. Write down what Ward Edwards claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ward Edwards before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ward Edwards ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ward Edwards

In research: Ward Edwards appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ward Edwards in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ward Edwards is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1927 births, 2005 deaths, 20th-century American psychologists, so understanding it makes those chapters shorter.
In everyday life: Look for Ward Edwards outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
