Research output: Contribution to journalArticlepeer-review


The criticisms of Falk et al. (2010) are addressed, and the question of whether claims made by Falk et al. (2007) are valid is revisited. This rebuttal contends that Falk et al. (2007) misconstrue Popper's role in philosophy of science and hence do not provide a strong test of their hypothesis. Falk et al. (2010) claim that they never made causal statements about the impact of zoo and aquarium visits in their 2007 study. Yet, this commentary shows that Falk et al. (2007) draw several unsupported, strong causal conclusions. The criticism that primary documents were not used in Marino et al. (2010) is also addressed, as this refutation demonstrates that the analysis was based on all available documents. Finally, this commentary aims, through its criticisms of Falk et al. (2007), to catalyze better-quality research on the effects of zoo and aquarium visits.
