We study decisions that involve choosing between different numbers of options under time pressure using eye-tracking to monitor the search process of the subjects. We find that subjects are quite adept at optimizing within the set of items that they see, that the initial search process is random in value, that subjects use a stopping rule to terminate the search process that combines features of optimal search and satisficing, and that subjects search more often in certain focal regions of the display, which leads to choice biases.

Purpose:The COVID-19 death-rate in Italy continues to climb, surpassing that in every other country. We implement one of the first nationally representative surveys about this unprecedented public health crisis and use it to evaluate the Italian government' public health efforts and citizen responses. Findings: (1) Public health messaging is being heard. Except for slightly lower compliance among young adults, all subgroups we studied understand how to keep themselves and others safe from the SARS-Cov-2 virus. Remarkably, even those who do not trust the government , or think the government has been untruthful about the crisis believe the messaging and claim to be acting in accordance. (2) The quarantine is beginning to have serious negative effects on the population's mental health. Policy Recommendations: Communications should move from explaining to citizens that they should stay at home to what they can do there. We need interventions that make staying following public health protocols more desirable, such as virtual social interactions, online social reading activities, classes, exercise routines, etc. -all designed to reduce the boredom of long term social isolation and to increase the attractiveness of following public health recommendations. Interventions like these will grow in importance as the crisis wears on around the world, and staying inside wears on people. 1 Roma Capitale (Municipality of Rome) convened our "COVID-19 International Behavioral Science Working Group" to (i) strengthen its public health policies and guidance, (ii) suggest new policies and guidance based on rigorous behavioral science, and (iii) develop empirical evidence about behavioral change. We report here empirical results and policy interventions aimed at achieving the objectives of the national Italian Government concerning the containment of the pandemic.

People are typically thought to be better off with more choices, yet often prefer to choose from few alternatives. By considering the perceived benefits and costs of choice, it is proposed that satisfaction from choice is an inverted U-shaped function of the number of alternatives. This proposition is verified experimentally. It is further hypothesized that differences in cognitive costs affect the relative location of the function's peak. Specifically, since-in large setsperceptual costs of processing alternatives varying in shape are greater than for alternatives varying in color, the peak of the satisfaction function for the latter will lie to the right of the former. This prediction is also validated. The paper emphasizes the need for an explicit rationale for knowing how much choice is "enough."
