While only a small minority of the participants think that Jennifer’s answer in the Chemistry scenario is true, 12.50% (95% CI (5.21%, 19.79%)), participants were split in the Party case with 51.25% (95% CI (40.23%, 62.27%)) answering “true.” The difference between both conditions was highly significant ( \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$t = 6.163, p < 0.001$$\end{document} t = 6.163 , p < 0.001 ), and a large effect size Cohen’s d of 0.908. 34 participants selected “wahr” in the Party case and “falsch” in the Chemistry case, indicating that true is ambiguous not just in English but also in German.
