The increased rate of social networking owes to the popularity of social networks among the common people and user personality has been considered as a principal component in predicting individuals\u2019 social media usage patterns. Several studies have been conducted to study the psychological factors influencing the social network usage of people but only a few works have explored the relationship between the user\u2019s personality and their orientation to spread rumors. This research aims to investigate the effect of personality on rumor spread on social networks. In this work, we propose a psychologically-inspired fuzzy-based approach grounded on the Five-Factor Model of behavioral theory to analyze the behavior of people who are highly involved in rumor diffusion and categorize users into the susceptible and resistant group, based on their inclination towards rumor sharing. We conducted our experiments in almost 825 individuals who shared rumor tweets on Twitter related to five different events. Our study ratifies the truth that the personality traits of individuals play a significant role in rumor dissemination and the experimental results prove that users exhibiting a high degree of agreeableness trait are more engaged in rumor sharing activities and the users high in extraversion and openness trait restrain themselves from rumor propagation.<\/jats:p>","DOI":"10.3233\/jifs-189864","type":"journal-article","created":{"date-parts":[[2021,3,30]],"date-time":"2021-03-30T14:37:15Z","timestamp":1617115035000},"page":"5425-5439","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["A psychologically-inspired fuzzy-based approach for user personality prediction in rumor propagation across social networks"],"prefix":"10.1177","volume":"41","author":[{"given":"V.","family":"Indu","sequence":"first","affiliation":[{"name":"University of Kerala, Thiruvananthapuram, India"},{"name":"Center for Research and Innovation in Cyber Threat Resilience (CRICTR), Indian Institute of Information Technology and Management-Kerala (IIITM-K), Thiruvananthapuram, Kerala, India"}]},{"given":"Sabu M.","family":"Thampi","sequence":"additional","affiliation":[{"name":"Center for Research and Innovation in Cyber Threat Resilience (CRICTR), Indian Institute of Information Technology and Management-Kerala (IIITM-K), Thiruvananthapuram, Kerala, India"}]}],"member":"179","published-online":{"date-parts":[[2021,3,27]]},"reference":[{"issue":"7","key":"e_1_3_2_2_2","first-page":"236","article-title":"Social Computing: The Impact on Cultural Behavior","volume":"7","author":"Almudawi N.A.","year":"2016","unstructured":"AlmudawiN.A., Social Computing: The Impact on Cultural Behavior, International Journal of Advanced Computer Science and Applications7(7) (2016), 236\u2013244.","journal-title":"International Journal of Advanced Computer Science and Applications"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0150989"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1145\/2503792.2503797"},{"key":"e_1_3_2_5_2","unstructured":"FardA.E.
