Judith ter Schure


Judith ter Schure's interests lie in foundations of statistics as well as in applied work. She divides her time between research and consultancy (before at CWI and significanthelp.nl, now at Amsterdam UMC), together with board membership (treasurer) of the Netherlands Society for Statistics and Operations Research (vvsor.nl). Her general motivation is the effect of statistics on society, which also inspires occasional writing for a wide audience – previously published by De Correspondent – and participation in popular science events like Nacht van de Wetenschap, ScienceBattle and Pint of Science.


Judith completed her Ph.D. dissertation on ALL-IN meta-analysis at CWI, which she defended successfully at Leiden University on April 7th 2022. A news article about her defense can be found on the Leiden University website (in Dutch) and on the CWI website (in English). The complete dissertation can be found in the Leiden University Repository and the CWI Repository.

ALL-IN meta-analysis helps scientists to prioritize research, interpret findings and design new studies – so efficiently accumulate scientific knowledge. The ALL-IN approach is bottom-up, especially suited to combine studies that have no common (top-down) stopping rule.


"Scientists need to make sure that all relevant trials are in when they hedge their bets on future research."


The research is motivated by the 'replicability crisis' in empirical science and the movements to reduce Research Waste (http://rewardalliance.net/) and make Research itself more Evidence-Based (https://evbres.eu/).
