## Scope
- How to evaluate trustworthiness based on the article
- Not how to evaluate the trustworthiness of the data set or the code
- Usually not assuming access to the actual methods/procedure/devices themselves
- Not how to evaluate trustworthiness based on relationships between article, code, and data
- Prereg vs. article comparisons?
- Excluding some general methods like image forensics, which don't apply to psychology or health RCTs (see intended audience)
### Trustworthiness vs. credibility
- Focus is limited to trustworthiness assessment, not credibility
- "This study provides biased or partial answers to the question" - credibility, evidence strength
- "This study cannot answer the question it claims to" - middle ground, where written conclusions cannot be trusted even if the methods and numerical results can be. Misalignment related, and therefore maybe a form of untrustworthiness?
- "There is reason to believe this study did not occur as described or its results cannot really be as described" - untrustworthiness
### Nomenclature
- Error; trustworthiness vs credibility; hierarchy and meaning for purposes of book should be clarified, without getting into definition wars
- Compare and contrast with the Four Validities
## Need for this book
- The industry trusted to produce truth has very few quality assurance mechanisms
- Need for parallel systems of verification. Operationalisation of the mantra that science is self-correcting, but only when we correct it
- Useful prior steps to replication
### Simulation studies
- Simulation study on over-representation of untrustworthy articles in highly cited ones
- Untrustworthy research crowds out trustworthy research
- Simulation study on data tampering
- The trustworthiness-credibility continuum; deemphasising fraud and thinking about negligence/recklessness/fraud
- Estimating the prevalence of errors
### Purpose
- Normalisation: in terms of us not being outsiders or weirdos, and in terms of these assessments being viable scientific projects with potentially publishable outputs
- Democratisation
### Intended audience
- The INSPECT-SR extended universe: health research synthesists, psychologists, and related fields who are doing within-article assessments
