Choosing, rejecting, and closely replicating, 30 years later: A commentary on Chandrashekar et al.

Abstract

Abstract In a ‘very close replication’ study using the same attributes as the original, Chandrashekar et al. (2021) report a failure to replicate some choose–reject problems documented in Shafir (1993). We find that several of the original attributes have changed their valence three decades later, and we compose new versions with updated attributes that fully replicate Shafir’s (1993) original findings. Despite their apparent exactitude, ‘very close replications’ across contexts or time, when stimuli may have changed their meaning or valence, can be highly misleading, further exacerbating replication concerns.
