I participated as a subject in a research study at Stanford involving race and stereotype threat in the early 2000s. The details are hazy, but the final readout was the distance I put my chair to a group of chairs that students of a particular racial group were supposed to sit. Evidently I put them in a position that was contrary to the effect the researcher was seeking. She intensely asked me a ton of questions about my background and eventually tossed my data point for having lived in a racially diverse area growing up. This wasn't a pre-inclusion criteria, but a possible act of scientific fraud. Huge bummer since there are honest people in every profession, and I imagine a lot of them didn't succeed the way that the fraudsters thrived.
