Using IMDB and Wikipedia to measure age bias

00:48 The stereotypes hidden in Internet images

Stereotyped assumptions about women’s ages and their perceived job suitability are enhanced by Internet imagery, according to new research. A study of hundreds of thousands of online images shows that women appear younger than men. This stereotype extends to the jobs that people perceive women do, with men being associated with roles such as CEO or head of research, while women were linked to occupations like cook or nurse. The research shows that these biases have been embedded into the training data for AI models and could affect future hiring. The researchers caution that society is at risk of creating a ‘self-fulfilling prophecy’ where these stereotypes shape the real world.
