The numerous studies on pseudoneglect have generated inconsistent results and disagreement concerning the underlying mechanisms. Most research supports the hypothesis that hemispheric lateralization is the main reason for the persistent leftward bias in spatial tasks. Findings on the influence of reading direction, handedness and participant age are largely contradictory. As a result of brain m...

Gender bias is an increasingly important issue in sports journalism. In this work, we propose a language-model-based approach to quantify differences in questions posed to female vs. male athletes, and apply it to tennis post-match interviews. We find that journalists ask male players questions that are generally more focused on the game when compared with the questions they ask their female co...

In randomized studies with missing outcomes, non-identifiable assumptions are required to hold for valid data analysis. As a result, statisticians have been advocating the use of sensitivity analysis to evaluate the effect of varying assumptions on study conclusions. While this approach may be useful in assessing the sensitivity of treatment comparisons to missing data assumptions, it may be di...

Integrating housing tenure in Instrumental Motivation Theory predicts a tenure gap in electoral participation, as homeowners would be more motivated to vote compared with tenants. The empirical question is whether this effect is causal or rather due to selection into different housing tenures. This question is tackled using coarsened exact matching (CEM) on data for 19 countries, allowing us to...

We derive the maximum bias functions of the MM -estimates and the constrained M -estimates or CM -estimates of regression and compare them to the maximum bias functions of the S -estimates and the τ -estimates of regression. In these comparisons, the CM -estimates tend to exhibit the most favorable bias-robustness properties. Also, under the Gaussian model, it is shown how one can construct a C...

Expansion of agriculture into new regions has often been followed by land degradation. In this paper, it is argued that the process of land development involves the selection of pioneer's with optimistic expectations about the robustness and carrying capacity of new land. Hence, there is a systematic bias towards over-exploitation and land degradation. The argument is shown to be an extension o...
