A key concern is low inter-reader reliability (IRR) seen between experts when interpreting challenging cases. While teams-based decisions are known to outperform individual decisions, inter-personal biases often creep up in group interactions which limit non-dominant participants from expressing true opinions. To overcome the dual problems of low consensus and inter-personal bias, we explored a solution modeled on bee swarms. Methods: Two separate cohorts; three board certified radiologists (Cohort 1), and five radiology residents (Cohort 2) collaborated on a digital swarm platform in real time and in a blinded fashion, grading meniscal lesions on knee MR exams. These consensus votes were benchmarked against clinical (arthroscopy) and radiological (senior-most radiologist) standards of reference using Cohen’s...

ABSTRACT We classify which complete multipartite graphs are intrinsically chiral.
