Audio long read: So you got a null result. Will anyone publish it? 17:44

2M ago17:44

17:44

The 'file-drawer problem', where findings with null or negative results gather dust and are left unpublished, is well known in science. There has been an overriding perception that studies with positive or significant findings are more important, but this bias can have real-world implications, skewing perceptions of drug efficacies, for example. Mu…

AIs built on Large Language Models have wowed by producing particularly fluent text. However, their ability to do this is limited in many languages. As the data and resources used to train a model in a specific language drops, so does the performance of the model, meaning that for some languages the AIs are effectively useless. Researchers are awar…
