title: Replication data for: "Application of thermography for monitoring stomatal conductance of Coffea arabica under different shading systems"

description: The primary objective of the data collection was to analyse the relationship between leaf temperatures and stomatal conductance. Data were collected under both environmentally controlled (laboratory) conditions as well as field conditions. Major variables studied and produced include thermographic indices derived from temperature measurements and stomatal conductance indices derived from a leaf porometer.

title: Replication Data for: How Do Indifferent Voters Decide? The Political Importance of Implicit Attitudes

description: A hallmark finding in the study of public opinion is that many citizens approach the political realm with one-sided attitudes that color their judgments, making attitude change difficult. This finding highlights the importance of citizens with weak prior attitudes, since they might represent a segment of the electorate that is more susceptible to influence. The judgment processes of citizens with weak attitudes, however, are poorly understood. Drawing from dual process models in psychology, I test the idea that citizens with weak explicit attitudes rely on implicit attitudes as they render political judgments. I find support for this conjecture in experimental and observational data. There are two main contributions. First, I show that an important and understudied segment of the electorate arrives at political decisions via automatic (but nonetheless predictable) mental processes. Second, I characterize the conditions under which implicit political attitudes matter more and less.

title: Replication data for: Estimating Individual Causal Effects

description: Most empirical work focuses on the estimation of average treatment effects (ATE). In this dissertation, I argue for a different way of thinking about causal inference by estimating individual causal effects (ICEs). I argue that focusing on estimating ICEs allows for a more precise and clear understanding of causal inference, reconciles the difference between what the researcher is interested in and what the researcher estimates, allows the researcher to explore and discover treatment effect heterogeneity, bridges the quantitative-qualitative divide, and allows for easy estimation of any other causal estimand. The framework I develop for estimating ICEs starts from the potential outcomes framework and then combines existing methods for matching in causal inference with a Bayesian model to impute missing potential outcomes. Researchers can use the resulting posteriors for the ICEs to derive the posterior for any other causal estimand by simple aggregation. In my dissertation, I first lay out the basic framework and estimation strategy. I then compare various models via simulation to test the effectiveness in recovering the true ICEs. Finally, I apply the model for estimating ICEs to two applications: a randomized field experiment on monitoring corruption from Olken (2007) and an experiment on the effectiveness of job training programs. I show the flexibility of the model in estimating ICEs for different types of outcome and treatment variables as well as with two-stage models using instrumental variables. I also show the various ways one can use the model to detect treatment heterogeneity and estimate a large number of different causal estimands.

title: The Value of Precision in Probability Assessment: Evidence from a Large-Scale Geopolitical Forecasting Tournament

description: Scholars, practitioners, and pundits often leave their assessments of uncertainty vague when debating foreign policy, arguing that clearer probability estimates would provide arbitrary detail instead of useful insight. We provide the first systematic test of this claim using a data set containing 888,328 geopolitical forecasts. We find that coarsening numeric probability assessments in a manner consistent with common qualitative expressions—including expressions currently recommended for use by intelligence analysts—consistently sacrifices predictive accuracy. This finding does not depend on extreme probability estimates, short time horizons, particular scoring rules, or individual attributes that are difficult to cultivate. At a practical level, our analysis indicates that it would be possible to make foreign policy discourse more informative by supplementing natural language-based descriptions of uncertainty with quantitative probability estimates. More broadly, our findings advance long-standing debates over the nature and limits of subjective judgment when assessing social phenomena, showing how explicit probability assessments are empirically justifiable even in domains as complex as world politics.

title: Replication Data for: More Human than Human: Measuring ChatGPT Political Bias

description: A standing issue is how to measure bias in Large Language Models (LLMs) like ChatGPT. We devise a novel method of sampling, bootstrapping, and impersonation that addresses concerns about the inherent randomness of LLMs and test if it can capture political bias in ChatGPT. Our results indicate that, by default, ChatGPT is aligned with Democrats in the US. Placebo tests indicate that our results are due to bias, not noise or spurious relationships. Robustness tests show that our findings are valid also for Brazil and the UK, different professions, and different numerical scales and questionnaires.

description: Guess the number is a simple P300-based brain-computer interface experiment. Its aim is to ask the measured participant to pick a number between 1 and 9. Then, he or she is exposed to corresponding visual stimuli and experimenters try to guess the number thought while observing event-related potential waveforms on-line. 250 school-age children participated in the experiments that were carried out in elementary and secondary schools in the Czech Republic. Electroencephalographic data from three EEG channels (Fz, Cz, Pz) and stimuli markers were stored. Additional metadata about the participants were collected (gender, age, the number thought by the participant, the guess of the experimenters, and various interesting additional information). The data are stored in the Brain Vision format.

title: Replication Data for: Urbanization Patterns, Information Diffusion and Female Voting in Rural Paraguay

description: We use a field experiment to evaluate the impact of two informational get-out-the-vote (GOTV) campaigns to boost female electoral participation in rural areas of Paraguay. We find that public rallies have a small and insignificant effect either on registration or voter turnout in the 2013 presidential elections. Households that received door-to-door canvasing treatment (D2D) are 4.6 percentage points more likely to vote. Experimental variation on the intensity of the treatment at the locality level allows us to estimate spillover effects, which are present in localities that are geographically more concentrated, which may favor social interactions and diffusion of information. Reinforcement effects to the already treated population are twice as large as diffusion effects to the untreated. Our results underscore the importance of taking into account urbanization patterns when designing informational campaigns.

These are based on individual-level ideal point estimates described fully in that article. Estimates are all in Shor-McCarty NPAT common ideological space to facilitate explicit comparisons across time and between states. The data spans 1993 through 2020, with 2,519 chamber-years of data (compared with 2,268 in the previous release).
