These lavishly designed doors belong to a building that sits in the courtyard of the Museum of Comparative Zoology and the Biological Labs at Harvard. Each door contain either insects or flowers in gold filigree. I use it to recognize the first and most basic categories on which the IAT was tested by Greenwald, McGhee, and Schwartz (1998) and one that often serves in our research as the baseline task to interpret data about human categories.
