A hiring manager tends to rate candidates favorably if their resumes contain no grammatical errors. This is an example of which type of selection bias?

The situation described illustrates the halo effect, which occurs when one positive attribute, such as the absence of grammatical errors on a resume, disproportionately influences a person's overall assessment of a candidate. In this case, the hiring manager allows the presence of flawless grammar to create a favorable impression, potentially overshadowing other, more relevant qualifications or skills that the candidate may possess. The halo effect demonstrates how one specific positive factor can shape perceptions in a way that affects decision-making, leading to potential bias in the hiring process.

In contrast, other biases mentioned would not directly relate to this scenario. Strictness bias usually involves a tendency to rate candidates harshly overall, while leniency bias refers to rating candidates more favorably than deserved. Similar-to-me bias occurs when an evaluator favors candidates who have similar backgrounds or traits as themselves, rather than being influenced by specific attributes like grammatical correctness.
