Progressively Cognitive Bias Correction (PCBC)

• PCBC is a framework that systematically identifies, quantifies, and mitigates cognitive biases in AI through iterative, adaptive interventions.
• It incorporates mechanisms such as uncertainty-weighted losses, ensemble belief revision, and neurosymbolic semantic alignment to correct biases.
• The approach leverages modular feedback and self-correction strategies to enhance model interpretability and decision accuracy across diverse applications.

Progressively Cognitive Bias Correction (PCBC) refers to systematic strategies for incrementally identifying, quantifying, and mitigating cognitive biases in artificial intelligence systems and decision frameworks. These biases arise as the result of inductive priors, heuristics, confounder effects, iterative learning restrictions, or model-driven artifacts that distort the inference, prediction, or action outputs of AI agents and human experts. PCBC targets both computational tractability and performance reliability by embedding corrective mechanisms that evolve alongside model learning, agent reasoning, or system interactions. The concept encompasses cognitive function formalizations in universal induction, uncertainty-weighted loss schemes, causal confounder disentanglement, neurosymbolic reasoning, self-correcting LLMs, and modular feedback mechanisms.

1. Foundations: Cognitive Biases as Priors, Heuristics, and Restrictions

Cognitive bias in the context of Universal Algorithmic Intelligence (UAI) is treated as inductive priors and decision heuristics, which direct search and learning within a universal predictor's model space (Potapov et al., 2012). In the "Ideal Minimal Intelligence" (IMI) framework, cognitive functions such as perception, attention, planning, and theory of mind are implemented as structured metaheuristics. These are formally understood as representations (e.g., Representational Minimum Description Length (RMDL)), planning trees, attentional resource allocations, or communication priors, serving to guide agents toward computationally efficient learning and inference without restricting their universality. Biases must be “soft” enough to be overridden in the presence of unexpected data, balancing efficiency with representation completeness.

In practical terms, PCBC encapsulates mechanisms to correct for these biases as they manifest throughout iterative induction or decision-making. This includes:

• Decomposing input history into subtasks (RMDL principle)
• Using mutual information as adaptive priors
• Restricting search using hierarchical action abstractions
• Allocating computation resources to informative data regions
• Embedding language and social interaction patterns as communication priors

2. PCBC in Ensemble Decision Systems and Belief Revision

Iterated belief revision frameworks characterize cognitive bias formally as restrictions on update rules (Papadamos et al., 2023). Anchoring, confirmation, and framing biases are encoded as threshold functions, narrowing heuristics, or early commitment strategies. PCBC in such systems involves progressive relaxation or adaptive recalibration of these restrictions, such as:

• Dynamic stubbornness functions for confirmation bias (i.e., lowering the evidence repetition threshold Dₜ(p) with more observations)
• Time-dependent framing functions for overconfidence (broadening interpretations as more evidence accumulates)
• Transitioning from anchoring heuristics toward model-averaged or unbiased ensemble updates when sufficient data is obtained

Simulation studies demonstrate that such progressively corrected approaches can improve truth tracking rates relative to static, biased methods, particularly under resource or data stream limitations.

3. Uncertainty-Weighted Correction in Co-training and Semi-supervised Learning

In semi-supervised volumetric medical image segmentation, PCBC refers explicitly to uncertainty-guided loss mechanisms in multi-branch co-training architectures (Gao et al., 19 Oct 2025). The core algorithm computes a pixel-wise uncertainty measure ($\mathcal{U}_p$) using the $L_1$ distance between the prediction probability vectors $P_{S,p}$ and $P_{T,p}$ from two collaborative network branches. The corrective PCBC loss dynamically emphasizes pixels where branch disagreement is highest:

$\mathcal{U}_p = \| P_{S,p} - P_{T,p} \|_1$

$$\mathcal{L}_{PCBC} = \frac{\sum_{p \in \Omega} \mathcal{U}_p \left( \| P_{S,p} - y_p^l \|_2^2 + \| P_{T,p} - y_p^l \|_2^2 \right)}{ \sum_{p \in \Omega} \mathcal{U}_p + \epsilon }$$

This strategy targets regions of cognitive uncertainty, thereby mitigating error accumulation from coarse to fine decoder scales and enhancing cross-branch consistency in semantic segmentation.

4. Causal Deconfounding, Contradiction Attention, and Disentanglement

In knowledge tracing for Intelligent Tutoring Systems, PCBC is achieved through the separation of student abilities (familiar/unfamiliar), causal effect subtraction, and the introduction of a contradiction attention mechanism (Zhou et al., 4 Mar 2025). The confounder—student historical correct rate distribution over question groups—can mislead internal representations (M) and predictions (Y). Disentangling this confounder through progressive, counterfactual interventions isolates true knowledge states and reduces amplification of bias.

The contradiction attention mechanism further shields the modeling of student abilities from transient guessing or mistakes, ensuring the system adapts as more data and feedback accumulate. Integration with Item Response Theory enhances both interpretability and resilience to data bias.

5. Modular Feedback and Iterative Debiasing in Expert Judgment

PCBC principles are embedded in modular interfaces for managing cognitive bias in expert domains (Whitehead et al., 2022). Here, a system of monitoring, output visualization, feedback, and action modules—collectively expressed as $$\text{MICE} = \{ \text{Monitoring}, \text{Output}, \text{Feedback}, \text{Action} \}$$—provides layered, context-sensitive interventions during interpretation tasks. Progressive correction is facilitated through repeated cycles of feedback and re-assessment, with modules addressing anchoring, confirmation, overconfidence, availability, and representativeness biases.

This architecture enables tailored, minimally disruptive bias correction across a range of expert group sizes and problem domains, with case examples in seismic interpretation, hazard assessment, and resource estimation. Iterative applications and expansion of the module libraries are poised to extend its reach.

6. Neurosymbolic PCBC and Semantic Alignment in Deep Learning

In convolutional neural networks, neurosymbolic frameworks embody PCBC by mapping internal filter activations to symbolic ASP representations and employing semantic similarity loss (Padalkar et al., 24 May 2024). Here, the semantic similarity loss function encourages the correlation of learned features with high-level desired concepts and discourages association with undesired ones:

$$L_{SS} = \sum_{i=1}^N \sum_{j=1}^K \left[ \lambda_b \sum_{b \in B} \text{cos\_sim}(r_j^i, r_b) - \lambda_g \sum_{g \in G} \text{cos\_sim}(r_j^i, r_g) \right]$$

Periodic recalibration of concept vectors ensures a dynamic, progressive approach, with experimental results confirming reduced bias and improved interpretability through successive retraining cycles.

7. Self-Correction and Explicit Debiasing in LLMs

PCBC paradigms extend to LLMs through self-correcting mechanisms based on “System-2” cognitive strategies (Anantaprayoon et al., 8 Mar 2025, Lyu et al., 5 Apr 2025). Both intent-aware self-correction and self-adaptive cognitive debiasing (SACD) enforce multi-aspect feedback and iterative refinement:

• Explicit debiasing prompts clarify the intention to avoid stereotypes
• Chain-of-Thought (CoT) reasoning explicates the cognitive process
• Structured feedback (e.g., metrics on coherence, comprehensiveness, objectivity) identify biased reasoning and direct iterative revisions

SACD decomposes prompt inputs, determines bias at the sentence level ($S = \{s_i, d_i\}$), analyzes bias types ($a = \text{Analysis}(x^*, S)$), and applies selective debiasing ($x_{db} = \text{Debiasing}(x^*, a)$), repeating this process until convergence. Experimental results in finance, healthcare, and legal tasks show substantial accuracy improvements under both single and multi-bias scenarios, validating the role of progressive correction.

8. Programmable Bias Induction and Regulation in Social Agents

In agent-based social simulations, PCBC can also encompass explicit quantification and control of cognitive bias (Liu et al., 16 Sep 2025). The CoBRA toolkit introduces a Cognitive Bias Index (CBI) derived from responses to standardized social science experiments and a Behavioral Regulation Engine that operates over input, activation, and parameter spaces. Control mechanisms include prompt numerical specification, representation engineering (RepE), and fine-tuning vectors (LoRA task vectors), allowing precise alignment of agent bias levels to prespecified targets. Evaluation reveals monotonic and smooth modulation of bias across different agent architectures and tasks.

PCBC comprises a spectrum of algorithmic and system-level solutions that continuously or periodically correct cognitive biases in real-world AI and human-in-the-loop settings. The common principle is adaptive intervention—whether through uncertainty quantification, causal disentanglement, structured feedback, symbolic alignment, or explicit parameter steering—to preserve generality and reliability while ensuring pragmatic efficiency and accuracy. Each adopted methodology tailors progressive correction to the particular data, model, and application context, as confirmed by empirical performance gains and enhanced interpretability across recent benchmarks.
