Interpretation

Interpretation of an experiment to test the effects of different formats of communication of indirect uncertainty around the COVID-19 R number on a public audience

This experiment set out to investigate the effects of the communication of indirect uncertainty (the level of consensus between different estimates) in combination with direct uncertainty (the statistical range around a point estimate) in a pair of experiments within a single online survey. The first experiment presented people with a text form of the information (...

Analysis

Analysis of an experiment to test the effects of different formats of communication of indirect uncertainty around the COVID-19 R number on a public audience

The R code for this analysis can be found in the OSF repository: https://osf.io/ypf6c/For each outcome, responses were analysed with a mixed two-way ANOVA, treating format as between-subjects factor and R range as a within-subjects factor. The Greenhouse-Geisser correction was applied when within-subjects factor violated the sphericity assumption (i.e., Mauchly's t...

Interpretation

Interpretation: what the public already know, want to know and need to know, about their personal risks from COVID-19

This Interpretation is based on work published in: https://doi.org/10.1098/rsos.201721 The interviews and the survey responses combined help give us an overall view of the public’s information needs regarding their personal COVID-19 risk, as of July 2020.The majority of participants clearly showed a desire for quantitative information about COVID-19 (much of which...

Interpretation

Interpretation of an analysis of the effects of different numerical formats on people’s perception of their risk of dying from COVID-19

This Interpretation is based on work published in: https://doi.org/10.1098/rsos.201721 The analysis of the data - from 2,500 members of the UK general public who were asked to rate how risky they felt five different numerical risk levels were (0.1%, 1%, 5%, 12%, 20%) when presented to them in a random order - confirms the collected findings of previous studies.

Rationale / Hypothesis

Finding out what the public already know, and want to know, about their personal risks from COVID-19

This Hypothesis/Theoretical rationale is based on work published in: https://doi.org/10.1098/rsos.201721One method of approaching risk communication is the ‘mental models’ approach, whereby researchers use both qualitative and quantitative methods to build up an understanding of the audience’s intuitive model of causality in a situation, as well as the probabilitie...

Research Problem

What information do the public need and want to know about their personal risk from COVID-19?

This Problem is based on work published in: https://doi.org/10.1098/rsos.201721Different communicators might have different aims when approaching the communication of personalized risk from COVID-19. Some may feel it important to encourage people to take mitigating actions, and hence to ensure that risks are perceived as relatively high to increase motivation [1,2]...

Research Problem

When presenting people with their personal risk from COVID-19, what format should they be shown the numbers in?

This Problem is based on work published in: https://doi.org/10.1098/rsos.201721Probabilistic information can be represented numerically in different ways, and research has shown that these different formats can affect the perception of likelihoods as well as affecting the ease with which people can make mental comparisons and manipulations of the information [1-5....
