Improving human performance in deepfake detection: limits of aggregation and human–AI collaboration

Source record kramer-2026-aggregation-human-ai · 2026 · Cognitive Research: Principles and Implications
Evidence tier: B (peer-reviewed-journal) · Verification: verified-abstract (compiler confidence: medium)
Bottom line: Individuals detected deepfake videos above chance but modestly; whole-sample aggregation helped, but confidence did not discriminate correct from incorrect trials, confidence-weighted pairing reduced accuracy, and gains from accurate AI guidance were offset by following incorrect advice.

Study design

Field Value
Design Four experiments, real-vs-deepfake video judgements. Exp1: response aggregation across the sample. Exp2: confidence ratings, metacognitive sensitivity, confidence-weighted fusion of participant pairs. Exp3-4: decisions before and after simulated algorithmic guidance, varying guidance accuracy and deepfake prevalence
Modality video
Stimuli YouTube clips and their corresponding deepfakes (generator not in abstract)
Participants (N) not recorded
N detail not in abstract
Topics human-detection, crowds, aggregation, metacognition, human-ai-teaming

Results

Metric Value Note
Individual accuracy above chance but modest and error-prone no values in abstract
Aggregation across full sample (Exp1) reliable accuracy gains wisdom of the crowd
Metacognitive sensitivity (Exp2) no evidence confidence modestly higher for correct decisions but did not reliably discriminate at trial level
Confidence-weighted fusion of pairs (Exp2) reduced accuracy
Simulated AI guidance (Exp3-4) helped when highly accurate; offset by following incorrect advice reliance unaffected by deepfake prevalence
