Trustworthiness Assessment
Using Forensic Meta-Science
Introduction

This is the skeleton of a book we are slowly writing. For the moment, you should not expect any meaningful content here.
This Open Source eBook provides materials for the semester-long Master’s seminar course “Estimating the Credibility of Past Research” that Ian delivers at the University of Bern’s Institute of Psychology.
This book is split into four parts:
- Concepts.
- Methods.
- Organising.
- Exercises.
How to use this book
This book is made up of individual Quarto (.qmd) files. Many of the exercises are easiest to complete in your own local copy of these .qmd files.
We suggest that you download a .zip of the contents of this book’s code and data from GitHub to run the code locally, complete the exercises, etc.
You can also copy and paste the code for any chapter directly from the website. Click the “</> Code” button on the top right of each page to see the full .qmd file’s code. You can copy and paste this into a .qmd file. However, it’s probably easier to download all the .qmd files and data as mentioned above.
Other learning resources
There are many excellent Open Source resources to learn simulation studies in R and {tidyverse}. Readers are encouraged to seek them out to support the materials already provided in this book. I can particularly recommend the following ones:
- Forensic Meta-Science: A hub for open-source forensic meta-science methods for assessing the trustworthiness of scientific research. Discover available guides and tools, or contribute to development.
- Heathers, J. (2025) An Introduction To Forensic Metascience eBook
