{"doi":"10.31234/osf.io/vtxza","title":"Algorithm aversion or appreciation? Three randomized field trials of personalized risk-communication nudges to encourage flu vaccination","abstract":"Artificial intelligence (AI) is increasingly used in healthcare to identify high-risk patients needing intervention. Communicating AI-derived personalized risk information is an untested health behavior change intervention; laboratory studies are mixed regarding patient favorability toward AI use. We ran a field test comprising three large-scale preregistered randomized controlled trials with over 90,000 unique patients. Nudge messages encouraged influenza vaccination in patients identified by a previously validated machine-learning algorithm to be at high risk for flu and flu-related complications. For patients informed they were at high risk, vaccination was 1.1–1.4 percentage points (3.3%–5.4%) higher vs. those not told they were at high risk, and 1.7–3.5 percentage points (3.3%–14.7%) higher vs. non-messaged patients. Therefore, informing patients of personalized risk may effectively encourage their acting on AI-derived information. Vaccination was similar across message arms that did vs. did not disclose the “algorithm,” indicating patients are neither averse to nor appreciative of recommendations that cite an algorithm.","journal":"PsyArXiv (OSF Preprints)","year":2023,"id":396746,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":2,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9543,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":618154,"name":"Amir Goren","orcid":"0000-0002-4388-8869","position":1,"is_corresponding":false},{"id":397760,"name":"Maheen Shermohammed","orcid":"0000-0002-4780-7325","position":2,"is_corresponding":false},{"id":430872,"name":"Donna M.
