title: Comment on "Ducklings imprint on the relational concept of 'same or different'".
abstract: Martinho and Kacelnik's (Reports, 15 July 2016, p. 286) finding that mallard ducklings can deal with abstract concepts is important for understanding the evolution of cognition. However, a statistically more robust analysis of the data calls their conclusions into question. This example brings to light the risk of drawing too strong an inference by relying solely onPvalues.
