Spreading Disinformation on Facebook: Do Trust in Message Source, Risk Propensity, or Personality Affect the Organic Reach of “Fake News”?

Open access

Abstract

There is considerable concern about the propagation of disinformation through social media, particularly for political purposes. “Organic reach” has been found to be important in the propagation of disinformation on social networks. This is the phenomenon whereby social media users extend the audience for a piece of information: interacting with it, or sharing it with their wider networks, greatly increases the number of people the information reaches. This project evaluated the extent to which characteristics of the message source (how trustworthy they were) and the recipient (risk propensity and personality) influenced the organic reach of a potentially false message. In an online study, 357 Facebook users completed personality and risk propensity scales and rated their likelihood of interacting in various ways with a message posted by either a trustworthy or untrustworthy source. Message source impacted on overall organic reach, with messages from trusted sources being more likely to be propagated. Risk propensity did not influence reach. However, low scores on trait agreeableness predicted greater likelihood of interacting with a message. The findings provide preliminary evidence that both message source and recipient characteristics can potentially influence the spread of disinformation.

Overview

Written from the paper’s full text.

TL;DR

In an online scenario study, Facebook users were more likely to say they would share, like, comment on, or react to a potentially fake news post when it came from a trusted close friend rather than an unknown contact. Risk propensity did not predict organic reach, while lower Agreeableness was associated with greater likelihood of propagating the post.

Key findings

  • The trust manipulation was effective: participants rated themselves more likely to trust information in the high-trust condition (M = 2.47, SD = 1.09) than in the low-trust condition (M = 1.69, SD = .92), t(349.65) = −7.34, p < .0005.
  • In multiple regression, trust condition significantly predicted organic reach (B = 1.55, SE = 0.36, β = .22, t = 4.31, p = .000), with higher reach for the higher-trust source.
  • Agreeableness had a significant negative effect on organic reach (B = −0.12, SE = 0.05, β = −.15, t = −2.60, p = .01): less agreeable people were more likely to extend the message’s reach.
  • Risk propensity was not significantly associated with organic reach (B = 0.00, SE = 0.02, β = .01, t = 0.20, p = .843), and the other four personality traits were non-significant; the model explained R² = .081, F = 4.33, p = .000.

Methods

  • Online study conducted via www.personalitytest.org.uk and Qualtrics; final sample was 409 participants, of whom 357 were Facebook users, with respondents from 44 countries and a majority relatively young female US students.
  • Measures included a 41-item Big Five personality questionnaire, Meertens and Lion’s 7-item Risk Propensity Scale, and an experimental trust manipulation: high-trust condition described a close friend’s Facebook post about political corruption, while low-trust condition described the same post from someone who had recently sent a friend request but was not really known.
  • Organic reach was measured as a summed scale of four self-rated likelihood items—share, like, comment, and react—with acceptable reliability (α = .80); analysis used a manipulation-check t-test and multiple regression predicting organic reach from trust condition, risk propensity, and the five personality variables.

Limitations

  • The paper states that only a single exemplar of a potential fake news item was used, so the Agreeableness effect may be specific to that item and requires replication with other materials; the election-campaign scenario also limits generalizability because trust is context dependent.
  • The paper states that the trust manipulation confounded trustworthiness with closeness of the relationship, that the truthfulness of the story was never made clear to participants, and that the study relied entirely on self-reported likelihood of interaction rather than actual behavioral observations.
  • The paper states that the measured variables accounted for only a small proportion of variance in self-rated likelihood of propagating disinformation (R² = .081), with unmeasured factors such as digital literacy, political interest, identity consistency, and general social media behavior likely playing a role; the convenience sample’s skew toward young female US students is also evident from the reported demographics.

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.

A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
