Retraction: why we removed an article about a link between exam results and ceiling height

Today we removed an article titled “Should we ditch big exam halls? Our research shows how high ceilings are associated with a lower score”, because the original research has been found to contain errors and has been retracted by the academic journal that published it.

The Conversation’s article, published on July 3, 2024, was based on a study published online by The Journal of Environmental Psychology on June 26, 2024. It looked at the impact of ceiling heights on the exam performance of Australian students, and found that even after accounting for other factors such as age or past exam experience, higher ceiling heights were statistically correlated with poorer exam results.

After the study was published, a query from a reader of the journal article led the authors to review their calculations.

The authors discovered some honest errors in their work, leading them to conclude that the relationship between ceiling heights and exam score was “more nuanced” than presented in the paper.

The revised research manuscript was reviewed by the same anonymous peer-reviewers who looked at the original research. One reviewer did not feel comfortable assessing the statistical corrections, one advised against publishing the corrected manuscript, and a third recommended revisions.

On this basis, the Journal of Environmental Psychology rejected the amended version. The journal’s response can be found here.

The authors, led by Isabella Bower, apologise for the error, and are working to resubmit their updated research to another journal.

The Conversation has decided that, in light of the current status of the research, the most appropriate option is to retract our coverage of the study. We are committed to providing accurate and reliable information, and to acknowledging errors in an open and transparent way when they occur.
