Although these systems can enhance task performance and decision-making, fairness preservation through bias reduction remains challenging. This study examines how agent-level biases shift and impact system-wide fairness. We use prompts to expose individual agents to group-favoring bias, then assess downstream impacts at the system level. To quantify the impact, we propose Favor Bias Strength (FBS), a zero-centered metric that decomposes bias alteration b","authors_text":"Paul Jen-Hwa Hu, Yuan Zhuang, Zejian Eric Wu, Zhongyi Jiang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2026-05-27T07:53:29Z","title":"Examining Agents' Bias Amplification versus Suppression in Multi-Agent Systems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.28098","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:b15871a5e171ae5f28c5ff19ddbbae4b3f830c399df84f8ff0b266ef77c1ffc7","target":"record","created_at":"2026-05-28T01:04:58Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"9fef993b5ef95f7fe69da86f03fdd4aca876300b2d148f56a7879f243de73cd8","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2026-05-27T07:53:29Z","title_canon_sha256":"421de9a9514d0bc8abec9b8d3062e84f5aa36d1a565b40b544013f4f58af1f4c"},"schema_version":"1.0","source":{"id":"2605.28098","kind":"arxiv","version":1}},"canonical_sha256":"9ef0ce759803e5c1523e101238e7e628600a9c628c3464a613803fe59403a03e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9ef0ce759803e5c1523e101238e7e628600a9c628c3464a613803fe59403a03e","first_computed_at":"2026-05-28T01:04:58.730737Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-28T01:04:58.730737Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bfMjzhav/UbMXs/MG0lbyHRoNAkO6ZNsWI67vS+bpTnVze1uzUSKGiXMi0MeqjAPqfPC3pGDLdFUb6UDQSFoBA==","signature_status":"signed_v1","signed_at":"2026-05-28T01:04:58.731194Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.28098","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b15871a5e171ae5f28c5ff19ddbbae4b3f830c399df84f8ff0b266ef77c1ffc7","sha256:29695a269ad0929c8807b871514a4ec0285a67fbfc52062137a235d554359408"],"state_sha256":"2aba267d434f15c72597ede9c3d2a1083ddcee74c2b8b054f2946c8b8655e0d9"}
