Online Images Amplify Gender Bias

Reviewed by Bri

"Online Images Amplify Gender Bias" by Douglas Guilbeault et al. in Nature[1]

examines "gender associations of 3,495 social categories (such as 'nurse' or 'banker') in more than one million images from Google, Wikipedia and Internet Movie Database (IMDb), and in billions of words from these platforms"

An implicit association test (IAT) methodology was used, which supposedly reveals unconscious bias in a timed sorting task, in the researchers' words "the participant will be fast at sorting in a manner that is consistent with one's latent associations, which is expected to lead to greater cognitive fluency [lower measured sorting times] in one's intuitive reactions." The test measured times when images were presented in sets, whose individuals could be separated both into male/female and into science/liberal arts (based on their Wikipedia biographies). Those images were labeled by other humans recruited via Amazon Mechanical Turk. Both the test subject, and the labelers, were adults from the United States, and the test subjects were screened to be representative of the U.S. population to include a nearly 50/50 male/female split (none self identified as other than those two categories). The images themselves – drawn from either Google Search or from Wikipedia – represented a preselected category list; the 22 occupations included immunologist, harpist, hygienist, and intelligence analyst, as examples, all found in WordNet.

Some test subjects were given a task related to occupation-related text prior to the IAT, and some were given a task related to images. The task was either to use Google search to retrieve images of representative individuals in the occupation, or Google search to retrieve a textual description of the occupation. A control group performed an unrelated Google search. Before the IAT was performed, the test subjects were required to indicate on a sliding scale, for each of the occupations, "which gender do you most expect to belong to this category?" The test was performed again a few days later with the same test subjects.

On the second test, subjects exposed to images in the first test had a stronger IAT score for bias than those exposed to text.

The conclusion drawn by the researchers based on the different IAT scores was that of the paper title, "images amplify gender bias", both explicitly as determined by the subject's assignments of occupation to gender on a sliding scale, and implicitly as determined by reaction times measured in the IAT. The researchers also determined – using the Mechanical Turk labeling – that images shown by Google search results exhibit a strong gender bias.
