Some Neuroeconomics Tips for Improving Investment Decision Making
Neuroeconomics — using neuroscience to study economic and social decision making — may often be associated with gambling, poker, and slot machines, but is increasingly being applied to more fundamental economic questions. Revolutions in science have and continue to inform our perceptions and decisions. Indeed, Robert Shiller, professor of economics at Yale University and co-creator of the Case-Shiller Index, said with regard to the “neuroeconomic revolution” that “a field of science can turn barren if no fundamentally new approaches to research are on the horizon.”
Scott Huettel, professor of neuroeconomics at Duke University, notes that neuroeconomics adds another page to the story of behavioral finance and its cousin behavioral economics. These two fields, he says, have operated as “bodies in isolation” that can predict general sets of biases. By further utilizing underlying features of human biology and the human brain, however, neuroeconomics enables Huettel to “predict whole sets of biases that turn out to be interrelated.”
So, what does this developing field offer to investment professionals? In an interview with Jason Zweig, the investing and personal finance columnist for the Wall Street Journal, Huettel explains how the brain’s natural processes affect financial decision making: the brain encodes in terms of reference points and in relative terms, inviting investors to overanalyze recent market trends — a dangerous temptation. In addition to discussing other common investor pitfalls and how emotions can impede investment decisions, he notes the findings of neuroscientists can also be helpful in simulating future situations and in setting aspirational levels to calibrate with current investments.
