With this regard, we stress that our reported
studies were the only ones performed (i.e. we did not keep unsuccesful
replications in the file drawer), except for a small-scale
preliminary pilot. In this pilot study, we asked participants to
perform sensory evaluations of pistachio nuts presented on red
or blue randomly-assigned plastic plates (12 participants for each).
Interestingly, even in this initial pilot we observed a significant
reduction of consumption with the red plates.
