What was believed to be true about including a photo in job applications?

Including a photo in job applications may lead to bias against less attractive candidates because it can influence hiring decisions based on appearance rather than qualifications or skills. Research has shown that unconscious biases can affect how hiring managers perceive applicants based on various physical attributes, including attractiveness. When a photo is included, it may shift the focus from a candidate's experience and competencies to their appearance, which can disadvantage those who do not fit conventional standards of attractiveness or may otherwise be prejudged based on visual impressions. This understanding encourages candidates to consider the implications of including a photo and how it may impact their chances of being evaluated fairly based on merit.
