However, less well understood are whether and how our communication patterns are similar or different over time and across various modes of communication. Here, we use data on the frequency of phone calls, text messages, and in-person interactions to examine the social signatures of more than 700 students in a university setting. Our analysis shows that although there is substantial turnover in participants\u2019 networks, participants\u2019 social signatures are persistent across time and consistent across\u00a0communication modes. Further, we find that communication networks that are mediated via phone calls or text messages are more stable than are in-person networks. Our results show that, likely due to limitations in cognitive and emotional resources, people maintain networks of relatively stable size and structure their communication within those networks in predictable patterns. Our findings may help with formalizing social network theories, explaining individual-level attitudes and behaviors and aggregate-level social phenomena, and making predictions and detecting abnormalities in applied fields.<\/jats:p>","DOI":"10.1007\/s41109-022-00448-0","type":"journal-article","created":{"date-parts":[[2022,2,24]],"date-time":"2022-02-24T12:03:01Z","timestamp":1645704181000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Evidence of the persistence and consistency of social signatures"],"prefix":"10.1007","volume":"7","author":[{"given":"Yue","family":"Li","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5026-2186","authenticated-orcid":false,"given":"Robert M.","family":"Bond","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2022,2,24]]},"reference":[{"issue":"6","key":"448_CR1","doi-asserted-by":"publisher","first-page":"643","DOI":"10.1016\/j.pmcj.2011.09.004","volume":"7","author":"N Aharony","year":"2011","unstructured":"Aharony N, Pan W, Ip C, Khayal I, Pentland A (2011) Social FMRI: investigating and shaping social mechanisms in the real world.
