We thank Jacobs, Persson, and Gärdenfors [1] for their reply to our proposed sequence bottleneck [2], in which they contend that there is overwhelming evidence for model-based learning in animals. If true, this would reduce the scope of our suggested sequence bottleneck. However, our interpretation of the literature on animal cognition differs significantly from theirs. This raises the question: how can two readings of the same literature be so different?
