This suggests that in tasks requiring up-to-date and detailed knowledge, such as accurately classifying uncommon lung cancer subtypes (e.g., sarcomatoid carcinoma) or identifying rare driver genes (e.g., precise identification of ROS1 fusion and its association with ALK-negative status), junior doctors may be more prone to knowledge-based biases due to insufficient clinical experience or incomplete knowledge updates. This evidence concerns the gene ROS1 and lung cancer.
