How can FRM optimise risk and uncertainty communications at the professional interface?
Why the reluctance to use uncertainty tools ....barriers?

Stakeholders in information pathways
As webs of influence vary, agendas vary, information needs vary,
risk communication strategies & appropriate tools will be totally different

BARRIERS?

The implication of this is that scientific uncertainty is an relatively unwelcome part of the risk message they are charged with translating for the public
PROFESSIONALS experience BINARY DECISION UNCERTAINTY (Decision rule uncertainty)
BARRIERS?
SCIENTIFIC UNCERTAINTYUncertainty in the science of flood forecasting and runoff prediction models are largely associated with their assumptions, structure, and boundary conditions, and confidence in validation procedures given uncertainties about climatic and societal futures
SCIENTIFIC AND DECISION MAKERS DIFFER IN THEIR UNDERSTANDING OF THE SOURCES OF UNCERTAINTY
Funders: EPSRC Grant: EP/FP202511/1www.floodrisk.org.uk
THE LANGUAGE OF SCIENCE IS OPAQUE TO THE NON-SCIENTIFIC PROFESSIONAL
BARRIERS?
If originally formulated in Bayesian terms, the language may be too opaque for translation to be effective – do professionals have sufficient statistical familiarity?
• Bayesian statistics ?• Prior probability
distributions?• fuzzy set methods ?• info-gap methods ?• NUSAP?
match tool to communication interface
The implication of this is that the language used to communicate the uncertainty must match the needs and agenda of the agencies involved in the communication being undertaken

THE WAY FORWARD: TRANSLATIONAL DISCOURSES?
Funders: EPSRC Grant: EP/FP202511/1www.floodrisk.org.uk
Our research (Faulkner et al 2007;McCarthy et al. 2009), both the interviews undertaken with professionals and from the ‘experiment’ undertaken at the co-location workshop in Exeter, found that :The power of VISUALISATIONS AND ANIMATIONS in realising the
uncertainty estimates was potentially great;The professionals questioned initially struggled to comprehend
scientifically defined flood forecast uncertainties (probabilistic and/or ensemble forecasts) without FURTHER TRANSLATION OF THE SCIENCE. When this was available as perhaps a ‘translational discourse’, the preparedness to embrace a more sophisticated expression of the model’s uncertainties was welcomed.
Better DECISION-SUPPORT TOOLS are needed.
