This influence acts as an external field, and it is introduced in the model by means of a probability $p$ of the agents to follow the media opinion. We performed Monte Carlo simulations on square lattices with different sizes, and our numerical results suggest a change on the critical behavior of the model, with the absence of the usual phase transition for $p>\\sim 0.18$. Another effect of the probability $p$ is to decrease the average relaxation times $\\tau$, that are log-normally distrib","authors_text":"Nuno Crokidakis","cross_cats":["cond-mat.stat-mech","cs.SI"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.soc-ph","submitted_at":"2011-11-24T13:17:16Z","title":"Effects of mass media on opinion spreading in the Sznajd sociophysics model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1111.5750","kind":"arxiv","version":2},"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":"sha256:163177ed39b27c44182939cbc4fc4109d53ea98bedd30bb1fe2422c6f9e29fb7","target":"record","created_at":"2026-05-18T04:05:48Z","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":"26b37571f4f9d3ece55b2a32b7c1a0373415965fc3d79943f7509b33e11594ac","cross_cats_sorted":["cond-mat.stat-mech","cs.SI"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.soc-ph","submitted_at":"2011-11-24T13:17:16Z","title_canon_sha256":"9f00bb846c52083ba02150311b5c551db5468b64b758142e31525f4bb99ecd6c"},"schema_version":"1.0","source":{"id":"1111.5750","kind":"arxiv","version":2}},"canonical_sha256":"5fc3b959701f374bc92ce9a8a31b71308b58b163b5ff95176d6a6eb4c2f1f995","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5fc3b959701f374bc92ce9a8a31b71308b58b163b5ff95176d6a6eb4c2f1f995","first_computed_at":"2026-05-18T04:05:48.144274Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:05:48.144274Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XFRjAFnsik/FuhjQpoThc+qr09cDr+jsiN7qpzEK80wMFPia9ZJ418XvEhjiiKnVYzE5SYiviFiZcfrrITiPAw==","signature_status":"signed_v1","signed_at":"2026-05-18T04:05:48.144948Z","signed_message":"canonical_sha256_bytes"},"source_id":"1111.5750","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:163177ed39b27c44182939cbc4fc4109d53ea98bedd30bb1fe2422c6f9e29fb7","sha256:5ed5559c82a762fb171ee62bdad8be33935849bfcc3a3b8307bdbdd0f3efbc90"],"state_sha256":"c2b27d90883bc3d1685681d1fb174fb69cdf1f605038e2cd426856ef818c1fa0"}
