Two obvious figures (black ink) facing each other. Butterfly-shaped red blot between the
figures; an elongated red blot behind each figure's head.
Naughty bits: penises and breasts (at anatomically appropriate positions for each figure).
This is the blot that supposedly can determine sexual preference. Most people see the two human figures. Both figures have prominent breasts and an equally prominent penis. If you don't volunteer the gender of the figures, you'll be asked to specify it. By the traditional interpretation, seeing the figures
as male is a heterosexual response (for test subjects of both sexes). Describing the figures as female or acknowledging the androgynous nature of the blot is supposed to be a homosexual response. Does it work? Not
really--many straights describe the figures as women, and not all gays give a gay response. A 1971 study at Mount Sinai Hospital in New York showed the traditionally heterosexual response (two male figures) to be declining in popularity.
