• Prior research found extremeness aversion effects to be common and robust. Nevertheless, most research neglected the spatial arrangement's influence on a consumer's choice and placed the compromise option of a choice set simultaneously in the spatial middle. Following these findings, five bachelor theses were conducted to investigate both aspects by analyzing numerical and spatial choice architectures – their data comprised three online surveys and three field experiments. This study aimed to compare their findings and analyze their data sets to search for overarching effects. Therefore, we hypothesized that there is either information-format compatibility or a general tendency towards the spatial middle of a choice set. To research this hypothesis, we brought the data sets into a comparable format, analyzed our findings, and conducted t-tests to test for statistical significance. Even though the study could not find overarching effects across the data, it supports the notion that a choice set's spatial arrangement, like the numerical one, can influence consumer behavior. Furthermore, it led to valuable insights for future research approaches concerning expanding extremeness aversion into a spatial dimension.
