Reviewer #1 (Public review): Endogenous Precision of the Number Sense

This important research investigates the precision of numerosity perception in two types of tasks and concludes that human performance aligns with an efficient coding model optimized for current environmental statistics and task goals.The proposed model receives compelling evidence from two numerosity perception experiments and a reanalysis of an existing dataset of risky decision-making.These findings have theoretical implications for our understanding of numerosity perception and decision-making as well as the ongoing debate on different efficient coding models.
