Fruit machine (homosexuality test)

Last updated

The "fruit machine" was a battery of psychological tests developed in Canada by Dr. Frank Robert Wake, [1] a psychology professor with Carleton University [2] in the 1960s. It was hoped that Dr. Wake's research program would be able to help the Government of Canada identify gay men working in the Public Service or to prevent gay people from obtaining government jobs. The subjects were made to view erotic imagery; "homosexual words," as well as an early form of lie detector to measure perspiration and pulse. The so-called machine was supposed to measure the subject's pupil dilation (pupillary response test), in response to the erotic images and words. The crude apparatus was constructed by the RCMP's Identification Branch.

The research program was employed in Canada between 1960 and 1964-ish as part of a campaign to eliminate all gay men from the civil service, the Royal Canadian Mounted Police (RCMP), and the Canadian Armed Forces (CAF). Thousands of Canadians lost their jobs or resigned and many died by suicide. Although funding for the project was cut off in the late 1960s, the RCMP investigations continued, and the RCMP collected files on well over 9,000 people. [3] [4]

The machine used a chair similar to that used by dentists. It had a pulley with a camera going towards the pupils, with a black box located in front of it that displayed pictures. The pictures ranged from the mundane to sexually explicit photos of men and women. It had previously been determined that the pupils would dilate in relation to the amount of interest in the picture, in a technique termed "the pupillary response test". [5]

People were first led to believe that the machine's purpose was to rate stress. After knowledge of its real purpose became widespread, few people volunteered for it.

Faulty test parameters

The functional mechanism of the "fruit machine" was pseudo-scientific, and its results inaccurate. First, the pupillary response test was based on fatally flawed assumptions: That the chosen visual stimuli would produce a specific involuntary reaction that could be measured scientifically with 1960s technology; that homosexuals and heterosexuals would respond to these stimuli differently with enough frequency to sort them; and that there were only two types of sexuality. [6] One physiological problem with the method was that the researchers failed to take into account the varying sizes of the pupils and the differing distances between the eyes. [5] [6] Other problems that existed were that the pictures of the subjects' eyes had to be taken from an angle, as the camera would have blocked the subjects' view of the photographs if it were placed directly in front. Also, the amount of light coming from the photographs changed with each slide, causing the subjects' pupils to dilate in a way that was unrelated to their interest in the picture. Finally, the dilation of the pupils was also exceedingly difficult to measure, as the change was often smaller than one millimeter. [5]

The idea was based on an unrelated study done by an American university professor, which measured the sizes of the subjects' pupils as they walked through the aisles of grocery stores. [5]

Brian Drader's 1998 play The Fruit Machine juxtaposes the fruit machine project with a parallel storyline about contemporary homophobia. [7]

Sarah Fodey's 2018 documentary film The Fruit Machine profiled the effects of the project on several of the people affected by it. [8]

<span class="mw-page-title-main">Pupil</span> Part of an eye

The pupil is a hole located in the center of the iris of the eye that allows light to strike the retina. It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil. The size of the pupil is controlled by the iris, and varies depending on many factors, the most significant being the amount of light in the environment. The term "pupil" was coined by Gerard of Cremona.

<span class="mw-page-title-main">Pupillary light reflex</span> Eye reflex which alters the pupils size in response to light intensity

The pupillary light reflex (PLR) or photopupillary reflex is a reflex that controls the diameter of the pupil, in response to the intensity (luminance) of light that falls on the retinal ganglion cells of the retina in the back of the eye, thereby assisting in adaptation of vision to various levels of lightness/darkness. A greater intensity of light causes the pupil to constrict, whereas a lower intensity of light causes the pupil to dilate. Thus, the pupillary light reflex regulates the intensity of light entering the eye. Light shone into one eye will cause both pupils to constrict.

Fruit, fruity, and fruitcake, as well as its many variations, are slang or even sexual slang terms which have various origins. These terms have often been used derogatorily to refer to LGBT people. Usually used as pejoratives, the terms have also been re-appropriated as insider terms of endearment within LGBT communities. Many modern pop culture references within the gay nightlife like "Fruit Machine" and "Fruit Packers" have been appropriated for reclaiming usage, similar to queer.
