Read this first","body":[{"value":"\u003Cp\u003EHaving more choices is generally considered a good thing \u2013 until you actually have to choose that one cell phone, one prescription drug plan or one car model from among a dozen or so options. Economists call that problem choice overload, and the frustration it causes can lead to poor decisions.\u003C\/p\u003E\u003Cp\u003E\u201cStandard economic theory will tell you that more choice is always better,\u201d said \u003Ca href=\u0022http:\/\/www.econ.gatech.edu\/people\/faculty\/besedes\u0022\u003ETibor Besedes\u003C\/a\u003E, an associate professor in the \u003Ca href=\u0022http:\/\/www.econ.gatech.edu\/\u0022\u003ESchool of Economics\u003C\/a\u003E at the Georgia Institute of Technology. \u201cTheoretically, that works out, but when you have to apply it, that\u2019s very different. When you give people a lot of options, they can get bogged down and, at some level, become unwilling to consider anything because it just gets too complicated.\u201d\u003C\/p\u003E\u003Cp\u003ETo help people make better choices when confronted by a large number of options, researchers have studied two decision-making strategies that break down the options into smaller groups that can be evaluated more effectively. One approach, analogous to a sports tournament, increased by 50 percent the likelihood that volunteer study subjects would make the best choice.\u003C\/p\u003E\u003Cp\u003EYet this tournament approach was the least liked by the study subjects, perhaps because it forced them to make more choices and to abandon decisions they had already made. On average, the tournament process also required more time than the other two approaches studied.\u003C\/p\u003E\u003Cp\u003EA paper describing the study has been published online by the journal \u003Cem\u003EThe Review of Economics and Statistics\u003C\/em\u003E, published by MIT Press. The research was sponsored by the National Institute of Aging, part of the National Institutes of Health.\u003C\/p\u003E\u003Cp\u003ESpurred by concerns over the large number of Medicare Part D prescription plans available, Besedes and collaborators from the University of Arkansas, Louisiana State University and the University of Connecticut initiated the study to compare strategies for making choices from large groups of options. They set up an online experiment that allowed them to study decisions made by 111 volunteers. The study subjects were asked to choose one option that would provide the best payoff from among 16 choices, and were rewarded by as much as $25 if they made optimal selections.\u003C\/p\u003E\u003Cp\u003EThe study evaluated three decision strategies:\u003C\/p\u003E\u003Cul\u003E\u003Cli\u003E\u003Cstrong\u003ESimultaneous choice\u003C\/strong\u003E, in which all 16 choices were considered together.\u003C\/li\u003E\u003Cli\u003E\u003Cstrong\u003ESequential elimination\u003C\/strong\u003E, which began with choosing one option from among four choices. Three additional choices were then added to the one chosen from the first group, and the process continued through five rounds until all but one option was eliminated.\u003C\/li\u003E\u003Cli\u003E\u003Cstrong\u003ESequential tournament\u003C\/strong\u003E, in which four groups of four options were randomly chosen by a computer, and the subjects were asked to choose one option from each group. The options chosen from the first four groups were then put into a finalist group from which the final selection was made. \u0026nbsp;\u003C\/li\u003E\u003C\/ul\u003E\u003Cp\u003EStudy subjects were allowed to use all three approaches, and were asked to specify their preferences. Overall, the sequential tournament approach produced the best decisions, but was the least popular of the methods, Besedes said. Considering all of the options together was the most popular, but produced the worst outcomes.\u003C\/p\u003E\u003Cp\u003E\u201cWe know from all the studies that we\u2019ve done that if you have a smaller choice set, you tend to do better,\u201d he explained. \u201cThere is a lot of information that you have to go through, and you have to understand what all of those things mean, and from that information, figure out what\u2019s best for you. You can\u2019t do that while choosing from 16 options at a time.\u201d\u003C\/p\u003E\u003Cp\u003EThe sequential elimination approach, in which volunteers were asked to repeatedly eliminate new options added to a choice they had already made, didn\u2019t perform any better than simultaneous choice. Besedes suggests that\u2019s because people tend to avoid making new decisions by sticking with their first choice \u2013 even when offered potentially better options.\u003C\/p\u003E\u003Cp\u003EThe experiment was done using a network of online volunteers enrolled by Vanderbilt University. The respondents were asked to choose from a group of cards that had different probabilities of payoff. This generic choice scenario was used to eliminate personal biases that might have arisen in choosing between real-world options such as insurance plans, Besedes said.\u003C\/p\u003E\u003Cp\u003EThe results of the study could be applicable to a wide range of decisions in which many options must be considered, Besedes said. While the initial focus was on choosing prescription drug plans, the approaches studied could be used for choosing retirement programs, health care insurance, automobiles, homes, cell phones and other products or services with many choices.\u003C\/p\u003E\u003Cp\u003E\u201cThis approach could apply to any situation in which you have a lot of options,\u201d he said. \u201cThe difference between choosing a Medicare Part D plan and picking a cell phone is that the cell phone decision is less important financially. If you choose the wrong retirement or prescription drug plan, the cost of making a mistake can be considerable. And by the time you realize you\u2019ve made a mistake, it may be too late to correct it.\u201d\u003C\/p\u003E\u003Cp\u003EBesedes offers advice to anyone trying to choose from many options:\u003C\/p\u003E\u003Cp\u003E1. Divide the options into piles of four \u003Cbr \/\u003E2. Choose the best option from each pile \u003Cbr \/\u003E3. Put the winners from the first round into a new finalist pile \u003Cbr \/\u003E4. Choose the best option from winners of the earlier four selections.\u003C\/p\u003E\u003Cp\u003EIn addition to Besedes, authors of the paper include Cary Deck from the University of Arkansas and Economic Science Institute; Sudipta Sarangi from Louisiana State University, DIW Berlin and the National Science Foundation; and Mikhael Shor from the University of Connecticut.\u003C\/p\u003E\u003Cp\u003EThis research was supported by the NIH National Institute on Aging under grant R21AG030184.
