The model achieved a 24.79% gain in fraud recall over autonomous baselines by routing uncertain transactions to human analysts while using a dynamic shadow price to manage human attention.", "body_md": "arXiv:2607.10317v1 Announce Type: new\nAbstract: Algorithmic decision systems in financial services often rely on data proxies that inadvertently encode structural inequalities. This paper introduces a hierarchical human-AI triage model for Point of Sale fraud detection in the Nigerian FinTech sector. Adopting a We Are All Equal worldview, we address the challenge of discrimination laundering, wherein the system misinterprets infrastructure related aleatoric noise such as rural network timeouts as fraudulent intent. We implement a three-tier routing policy utilizing a calibrated ensemble model as a primary filter. The policy routes transactions characterized by epistemic uncertainty such as cold start new accounts to specialist analysts while reserving high stakes cases for a senior supervisor. To manage finite human capacity, we utilize a dynamic shadow price to ration human attention and implement a random audit mechanism to prevent human skill atrophy. Our experimental results demonstrate a statistically significant 1.88\\% complementarity gap and a 24.79\\% percentage point gain in fraud recall over an autonomous baseline. Crucially, the model reduces the regional performance gap from 19.43 to 2.88 percentage points, neutralizing structural bias. Hierarchical collaboration provides a robust mechanism for substantive equality of opportunity, ensuring that rural accounts are not excluded from the digital economy due to environmental brute luck.", "url": "https://wpnews.pro/news/neutralizing-structural-inequality-in-the-nigerian-fintech-sector", "canonical_source": "https://arxiv.org/abs/2607.10317", "published_at": "2026-07-14 04:00:00+00:00", "updated_at": "2026-07-14 04:34:41.314913+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-ethics", "ai-policy", "machine-learning"], "entities": [], "alternates": {"html": "https://wpnews.pro/news/neutralizing-structural-inequality-in-the-nigerian-fintech-sector", "markdown": "https://wpnews.pro/news/neutralizing-structural-inequality-in-the-nigerian-fintech-sector.md", "text": "https://wpnews.pro/news/neutralizing-structural-inequality-in-the-nigerian-fintech-sector.txt", "jsonld": "https://wpnews.pro/news/neutralizing-structural-inequality-in-the-nigerian-fintech-sector.jsonld"}}
