Two social lives: how differences between online and offline interaction influence social outcomes

Open access
Lieberman, Alicea, Schroeder, Juliana·2020·Current Opinion in Psychology

Abstract

For hundreds of thousands of years, humans only communicated in person, but in just the past fifty years they have started also communicating online. Today, people communicate more online than offline. What does this shift mean for human social life? We identify four structural differences between online (versus offline) interaction: (1) fewer nonverbal cues, (2) greater anonymity, (3) more opportunity to form new social ties and bolster weak ties, and (4) wider dissemination of information. Each of these differences underlies systematic psychological and behavioral consequences. Online and offline lives often intersect; we thus further review how online engagement can (1) disrupt or (2) enhance offline interaction. This work provides a useful framework for studying the influence of technology on social life (119/120).

TL;DR

This review proposes a framework organizing the psychological and behavioral consequences of online versus offline interaction around four structural differences: fewer nonverbal cues, greater anonymity, more opportunity to form and bolster ties, and wider dissemination of information. It further reviews how online engagement can either disrupt or enhance offline social connection.

Key findings

  • Four structural differences between online and offline interaction each carry systematic consequences: text-based communication reduces observers' accuracy in judging communicators' thoughts and feelings and makes communicators appear less thoughtful and emotional (i.e., potentially dehumanizing), while hearing a voice uniquely humanizes.
  • Anonymity licenses disinhibition and aggression, but can also inhibit connection: in a field experiment randomizing 100,000 online daters to anonymous versus non-anonymous profile viewing, anonymized users viewed more profiles but ended up with fewer matches.
  • Online media expand network size (average 338 Facebook Friends) but do not appear to change the number of significant contacts, which remains around 5 intimate friends, 15 close friends, 50 general friends, and 150 acquaintances; larger networks (>40) mean less time spent with each contact.
  • Wider dissemination cuts both ways: in an analysis of 126,000 stories from 2006–2017, false stories spread more widely and quickly than true ones, and machine learning models identified users' political affiliation (Democrat vs. Republican) with 85% accuracy.

Methods

  • Narrative review / conceptual framework paper (Current Opinion in Psychology), not an empirical study; no primary data collection or analysis is reported.
  • The authors synthesize prior findings, including cited experiments and field studies (e.g., the 100,000-dater anonymity experiment; the 126,000-story diffusion analysis; smartphone-use experiments on parental attention and navigation), to illustrate each structural difference.
  • Organization is thematic: four structural differences, then a section on how online interaction disrupts or enhances offline interaction, followed by proposed future research questions.

Limitations

  • The paper states no limitations; it declares only "Nothing declared" under Conflict.
  • Evident from the text: this is a selective narrative review rather than a systematic one, so the cited evidence is illustrative rather than exhaustive, and the four-difference framework is proposed rather than empirically tested.
  • Several claims rest on single studies or working papers (e.g., the voice/paralanguage working paper, individual field experiments), and the authors themselves flag open questions about how evolving technologies (video chat, customizable voices) may blur the online–offline distinction.

The “Greater anonymity online” section separately discusses moral outrage on social media. Neither passage says that missing cues exaggerate the perceived intensity of users’ outrage.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
