A decision maker is characterized by two binary relations. The first reflects decisions that are rational in an “objective” sense: the decision maker can convince others that she is right in making them. The second relation models decisions that are rational in a “subjective” sense: the decision maker cannot be convinced that she is wrong in making them. We impose axioms on these relations that allow a joint representation by a single set of prior probabilities. It is “objectively rational” to choose f in the presence of g if and only if the expected utility of f is at least as high as that of g given each and every prior in the ...
with a yes-or-no answer, depending on the values of some input parameters. For example, the problem "given two numbers x and y , does x evenly divide y ?" is a decision problem. The answer can be either 'yes' or 'no', and depends upon the values of x and y . Decision problems are closely related to function problems , which can have answers that are more complex than a simple 'yes' or 'no'. A corresponding function problem is "given two numbers x and y , what is x divided by y ?". They are also related to optimization problems , which are concerned with finding the best

The opportunity for opportunity analytics — JT on EDM
Some time ago Neil Raden and I did some research on analytics. It was clear as we did this that there were two main threads of analytic use in companies – risk analytics and opportunity analytics. I blogged before on the use of analytics to manage risk one risk at a time so I thought I would write about opportunity analytics. Risk analytics are about using historical data to make a prediction about the risk of a particular customer, a particular transaction going or being bad in some way. Risk analytics help you estimate and account for the downside risk of a decision – if I get this wrong, what’s the worst ... market research, surveys and trends

Evolution Poll Gallup
PRINCETON, NJ -- Although most scientists subscribe to the theory of evolution as the best explanation for the origin of human beings, a recent Gallup poll shows that the American public is much more divided in its own beliefs. Americans choose "creationism" over "evolution" when asked which of these two terms best describes human origins, but slightly larger numbers of Americans choose one of two evolutionist explanations than choose a strict creationist explanation when given a choice between three specific views. At the same time, only about a third of the public say that Charles Darwin�s theory of evolution ... industry trends, business articles and survey research

Is Google far too much in love with engineering?
It's nice if a pilot has a background in flying. It's really quite special if a colonoscopist has a background in medicine. But does everyone who heads up a department at Google really need to have a background in engineering? I should be lying in the sun rather than pondering this existential mind-twister, but I was moved past reluctance by a blog post written by Don Dodge , developer advocate at Google. Dodge, who used to perform advocacy at Microsoft, wrote this post to celebrate surviving--I'm sorry, I mean enjoying--six months at Google. In a section titled "Engineering Rules!," Dodge offered the ... market trends, news research and surveys resources

Beyond statistical inference: A decision theory for science
Traditional null hypothesis significance testing does not yield the probability of the null or its alternative and, therefore, cannot logically ground scientific decisions. The decision theory proposed here calculates the expected utility of an effect on the basis of (1) the probability of replicating it and (2) a utility function on its size. It takes significance tests—which place all value on the replicability of an effect and none on its magnitude—as a special case, one in which the cost of a false positive is revealed to be an order of magnitude greater than the value of a true positive. More realistic ... technology research, surveys study and trend statistics

What is the Psychoanalytic theory of consumer decision making ...
Psychoanalytic theory—One of the initial approaches to the study of consumer behaviors in marketing used Freud’s Psychoanalytic Theory as its basis. This approach viewed consumers as having complex, subconscious motivations for purchasing. Motivation research in marketing—While very popular in the late 1950s, this area of study—known as motivation research—received much less attention through the 1960s and 1970s.
