End the search quickly: Pigeons (Columba livia) and humans (Homo sapiens) share the same bias

Comments on an article by W. T. Herbranson et al. (see record 2022-07304-001). The article by Herbranson et al. illustrates the care that must be taken, both in designing comparative research and in interpreting the findings, to understand how specific features of experimental design impact each species' choices. Herbranson et al. presented to pigeons a decision-making challenge known informally as "The Secretary Problem", a problem cast in the form of selecting a candidate for a job. The task is to make a single choice among a finite set of options when these options are presented in succession. The chooser must select a given option or pass on to the next without knowing what the remaining options are. Decisions are final-one either rejects an option when it appears or selects that option, ending the search. The authors trained pigeons to recognize the "reward value" of five different colors on keys that they could peck. Herbranson et al. subsequently replicated the study with humans, presenting humans with probabilistic outcomes (rather than the certain outcomes of varying value presented in earlier studies with humans). Their aim was to explore the consequences of altering reinforcement options on humans' choices, so as to understand more fully the ways in which pigeons and humans approach this problem. Herbranson et al.'s work is an example of the power of carefully constructed comparative behavioral experiments to expand the understanding of ourselves and other species in unexpected ways.
