Sternberg and Grigerenko Studied the Effects of Parasitic Infections on Cognitive

Sternberg and Grigerenko studied the effects of parasitic infections on cognitive functioning in several field sites around the world. They argued that field research offers several advantages over laboratory research. All of the following are advantages they cited except

A) some conditions (e.g., extreme heat) could never be duplicated in the lab
B) discoveries that result from the research can have immediate beneficial effects on people
C) field research can correct misconceptions that might arise from laboratory research
D) field research automatically allows the experimenters greater experimental realism
