I took the Project Implicit Age test, and my results showed a strong to moderate automatic preference for younger people over older people. A large percentage of respondents had similar results, which made it clear that this type of bias is fairly common. I wouldn’t say I favor one age group over another, but this result shows that bias can still influence my decisions without me realizing it.
In hiring, this matters because implicit bias can affect both reliability and validity in the selection process. Reliability refers to consistency in how candidates are evaluated, and bias can lead to inconsistent judgments even when candidates provide similar responses (W5 Lecture 2 – Introduction to Selection). For example, an older candidate might be perceived as less adaptable or less comfortable with technology, even when their experience shows otherwise. Validity is also affected because the selection process may not accurately measure job-related skills and qualifications. Instead, decisions can reflect assumptions rather than actual ability, which reduces how well the process predicts job performance (Selection Outline; Chamorro-Premuzic & Steinmetz, 2013).
This connects to structured interviews. Unstructured interviews allow more room for bias, while structured interviews use standardized questions and scoring criteria, which helps reduce bias and improve consistency (W5 Lecture 4 – Increasing Interview Effectiveness). Research also shows that standardizing hiring processes and focusing on job-related criteria can help minimize unconscious bias (Knight, 2017).
One way I could reduce implicit bias is by using structured scoring tools tied directly to the job description. This keeps evaluations focused on relevant qualifications instead of impressions. Overall, this test showed me that even unintentional bias can affect hiring decisions, which is why structured processes are important.
