Evidence synthesis, integrity, reproducibility, grading and corrections
Research, evidence and the science-policy interface

04The subject
The subject, methods and measures and debates and bodies
The field and its scope
For researchers, evidence synthesists, science advisers and the analysts who use their work, who need to judge how knowledge about risk is produced, graded, corrected and brought to decisions.
Quantities and units
Methods and their limits
Each method is listed with what it assumes and where it fails.
What the field debates
Bodies that set practice, and the data they publish
Bodies and standards are named so learners can find and apply their published work; the Academy teaches their use and links to the publisher, and no affiliation is implied.
05The method
From a prior to a published claim: why a significant finding is often false, and what that does to advice
The probability that a published positive finding is true depends on the prior odds that the hypothesis was true, the study's power and its false-positive rate; low priors and low power make most significant results wrong, which is why evidence grading reads the body of evidence rather than a single paper.
Sources: Ioannidis, Why Most Published Research Findings Are False (2005); Open Science Collaboration, Estimating the reproducibility of psychological science (2015); Guyatt and others, GRADE: an emerging consensus on rating quality of evidence and strength of recommendations (2008); Pielke, The Honest Broker: Making Sense of Science in Policy and Politics (2007); Munafò and others, A manifesto for reproducible science (2017).

11Questions
Questions, answers and key terms
Is study here free?
Yes. Every course and learning material of Risk Academy, led by the Nexus Consortium, is free to study, self-paced or with a cohort. Ordinary participation has no fee; paid work, internships and fellowships are separate arrangements.
What does completing a course give me?
A completion record: the course, its version, the date and what was assessed, private by default and shared by you. It stacks into discipline, department and programme achievements. A record states what was studied and assessed and does not certify competence; it is not a licence, a professional title or an employment status.
Where do the data and the places come from?
Every faculty teaches on a twin of a real place built from open data; each layer carries its provider, licence and date, and every result on the Academy states its source. Maps and figures are indicators for teaching, never an assessment of a place.
How do I take part beyond the courses in research, evidence and the science-policy interface?
Form a competence cell of three to seven people, study a shared pathway, take a supervised assignment in the National Working Groups, or bring a cohort from your institution. For organisations.
