Data Level: Uncovering Hidden Heterogeneity
Endogenous bias at the data level often stems from neglecting inherent spatial structures like heterogeneity, leading to misleading aggregate conclusions.

Case Study: Simpson's Paradox & Demographic Diversity in Cook County
The study highlights how aggregate statistics (e.g., total population hospital accessibility) can mask critical disparities within subpopulations. Using parallel coordinates and spatial distribution maps, it was revealed that different racial groups in Cook County face distinct healthcare accessibility challenges. For instance, White individuals showed higher accessibility in central/southern areas, while Black individuals had higher accessibility in northern areas, differing significantly from the county-wide average. Ignoring this inherent heterogeneity leads to ethically indefensible outcomes and misallocation of resources.
Value/Impact: Ensures equitable resource allocation by revealing sub-population specific needs.
Relevance: Critical for fair urban planning and public health policy.
Modeling Level: Auditing Algorithmic Assumptions
Bias arises when model assumptions (e.g., linearity) are inconsistent with geographic reality or when parameters are improperly set.

Errors at Boundaries
GWR fitting errors are concentrated in regions where estimated coefficients change abruptly, indicating violations of local linearity assumptions.
Case Study: Dynamic Parameter Adjustment for KDE
Parameter settings, such as bandwidth in Kernel Density Estimation (KDE), critically influence the accuracy of spatial pattern extraction. An inappropriate bandwidth can obscure local details (too large) or exaggerate noise/create false centers (too small). Dynamic visualization allows analysts to interactively adjust bandwidths in real-time, observing the impact on spatial patterns. This helps in selecting optimal parameters, reducing endogenous bias, and ensuring that derived patterns accurately reflect underlying data, preventing misdirection of resources.
Value/Impact: Prevents creation of 'false centers' and ensures accurate resource targeting.
Relevance: Essential for reliable crime mapping, urban density analysis, and environmental monitoring.
Interpretation Level: Mitigating Grouping-Induced Bias
Bias at this stage stems from subjective choices in aggregating, classifying, and visualizing results, which can create misleading narratives.

Case Study: Multi-Grouping for Healthcare Accessibility
The Modifiable Areal Unit Problem (MAUP) demonstrates how spatial analysis results vary significantly based on how a study area is partitioned. This study applied multi-grouping visualization to reveal that classifications across different grid resolutions yielded inconsistent results for a significant portion of the area. In the Cook County healthcare accessibility case, separately visualizing accessibility for different racial groups, instead of just the aggregated total, revealed significant disparities. Black and American Indian communities experienced lower accessibility than the overall average, highlighting how non-spatial grouping choices profoundly impact conclusions and ethical outcomes.
Value/Impact: Ensures policies are based on realistic, granular insights, not misleading aggregates.
Relevance: Crucial for equitable public service provision, resource allocation, and social justice initiatives.
