A review of the effects of uncertainty in public science communication
Open accessAbstract
Uncertainty is inherent to science and science communication. However, the evidence appears mixed regarding whether portraying uncertainty in science communication has positive or negative effects. We review a diverse range of experimental literature ( k = 48; from 40 searches and 8000 retrievals), summarize the extant findings, and observe how the effects vary across four different types of communicated uncertainty ( deficient, technical, scientific, and consensus uncertainty). The results indicate that most findings of negative effects (such as reduced credibility and beliefs) are from experiments that operationalized uncertainty as disagreement or conflict in science ( consensus uncertainty). In this review, consensus uncertainty was never found to have positive effects. In contrast, uncertainty in the form of quantified error ranges and probabilities ( technical uncertainty) in these studies has had only positive or null effects, not negative effects. We also highlight frequent moderators of the effects of uncertainty, such as prior beliefs and worldviews.

Written from the paper’s full text.
TL;DR
This systematic review synthesizes 48 papers containing 68 experiments and 38,947 participants on how portrayals of uncertainty in public science communication affect audience beliefs, attitudes, and behaviors. It finds that effects depend strongly on the type of uncertainty: consensus/conflict uncertainty is consistently negative, technical quantified uncertainty is positive or null, deficient uncertainty is mixed, and scientific uncertainty is rarely studied.
Key findings
- Across 48 journal articles/book chapters and 68 experiments with 38,947 total participants, uncertainty portrayals showed negative, positive, and null effects depending on how uncertainty was operationalized.
- Consensus uncertainty—expert disagreement, controversy, or conflicting evidence—was most clearly associated with negative main effects; the review found no instance of consensus uncertainty producing positive main effects.
- Technical uncertainty—quantified error ranges, probabilities, or confidence intervals—showed no negative effects and instead had positive or null effects. Deficient uncertainty had mixed effects, while scientific uncertainty had mixed but tentative effects because it was studied infrequently.
- Effects were often conditional on prior worldviews or topic opinions, trust in science/scientists, beliefs about uncertainty’s role in science, and topic. For example, expert consensus increased policy support only among people with high trust in scientists and decreased it among those with low trust; technical uncertainty lowered perceived risk relative to consensus uncertainty only among those high in deference to science.
Methods
- Systematic review of experiments that manipulated uncertainty in a public-facing science message and compared outcomes with a no-uncertainty control, measuring beliefs, attitudes, or behaviors. Excluded non-experiments, private/interpersonal communication, comprehension outcomes, multi-message designs, and visual uncertainty depictions.
- Searches used Google Scholar with 40 searches (eight uncertainty-related terms crossed with five science-communication variants), examining the first 200 results per search for 8,000 retrievals, plus reference and citation chasing. Final set: 48 journal articles/book chapters, 68 experiments, 38,947 participants.
- Studies were coded by four uncertainty types (deficient, technical, consensus, scientific), sample type, topic, main effects, and conditional effects. The first author coded manifest and latent content, consulting the second author to resolve ambiguities.
Limitations
- Stated: publication bias may affect the literature; many included studies used very small samples that may not replicate; inclusion criteria and search methods may have missed relevant experiments, including work in other fields or with different terminology; alternative uncertainty typologies or broader inclusion criteria could reveal different patterns; and heterogeneity across topics, stimuli, outcomes, samples, and years may confound conclusions.
- Evident from the text: the review is a narrative synthesis rather than a quantitative meta-analysis, so effect sizes are not pooled; coding was primarily done by the first author with consultation rather than independent double-coding, and no formal inter-coder reliability statistic is reported.

Section 2.1.1.3 explains that the accuracy of reporting uncertainty depends on whether it portrays technical or deficient uncertainty.

The Results section reports that caveats appeared in only 14–15% of press releases, so describing them as 'often' included overstates their frequency.

The Results’ internal metaanalysis reports a small reduction in trust in the source for verbal uncertainty, but not numerical uncertainty. It also reports that both verbal and numerical expressions increased participants’ perceived uncertainty about the numbers. Thus the ‘but not numerical’ distinction does not hold for certainty; the measured outcome was perceived certainty of the numbers, rather than participants’ own general level of certainty.

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 2026-10-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
