When offered spinach or a cookie, how do you decide which to eat? Do you go for the healthy choice or the tasty one? To study the science of decision making, researchers in the lab of Caltech neuroeconomist Antonio Rangel analyze what happens inside people's brains as they choose between various kinds of food. The researchers typically use functional magnetic resonance imaging (fMRI) to measure the changes in oxygen flow through the brain; these changes serve as proxies for spikes or dips in brain activity. Recently, however, investigators have started using a new technique that may better tease out how you choose between the spinach or the cookie—a decision that's often made in a fraction of a second.

When making decisions based on multiple interdependent factors—such as what combination of stocks and bonds to invest in—humans look at how the factors correlate with each other, according to a new study by researchers from Caltech and University College London.

The sky is gray, but you're not sure if the clouds will clear or rain will pour. Do you grab an umbrella when you go outside? Such decisions are filled with ambiguity, and we're faced with them daily. "Almost every decision has some ambiguity," says Kota Saito, an economist who develops empirical and mathematical models on how people make decisions—insight that can inform socioeconomic policy. This fall, he joins Caltech as an assistant professor and the newest faculty member of the Division of the Humanities and Social Sciences.

We've all heard the predictions: e-commerce is going to be the death of traditional commerce; online shopping spells the end of the neighborhood brick-and-mortar store. While it's true that online commerce has had an impact on all types of retail stores, it's not time to bring out the wrecking ball quite yet, says a team of researchers from Caltech.

Parents pursuing adoption within the United States have strong preferences regarding the types of babies they will apply for, tending to choose non-African-American girls, and favoring babies who are close to being born as opposed to those who have already been born or who are early in gestation. These preferences are significant and can be quantified in terms of the amount of money the potential adoptive parents are willing to pay in finalizing their adoption.
