I took a series of online tests based on that principle: it’s too noisy. Most of the variance is almost certainly random. (I remember getting different results from taking the same test twice, but I’m unsure, and it could be explained as an attempt to deny being racist.) Answers near the end of the test are likely to be faster and more accurate as subjects get used to it. The choice of inputs is loaded: I was unable to recognize some images (photographs of people whose race I couldn’t tell, and a terrible drawing of a menorah that took several iterations to identify); connotations vary across cultures (Blacks are mostly Christian in North America and Muslim in Europe) and people (the test on homosexuality included words like “natural”, which I think of as neutral rather than good, and “perverse”, which I think of as good rather than bad).
