Which type of evidence is based on opinions of individuals?

• A. Empirical Evidence
• B. Gender Harassment
• C. Unwanted Sexual Attention
• D. Testimonial Evidence

Answer: (D)

The key idea is distinguishing types of evidence by how they’re produced. Testimonial evidence is evidence based on what people say—individuals’ statements about their experiences, observations, or beliefs. This is opinion-based because it comes from personal accounts, which can be influenced by memory, perspective, and bias, but they provide direct insight into what someone experienced or believes.

Empirical evidence, in contrast, comes from observable data, measurements, experiments, or physical facts that can be verified independently of personal opinions. The remaining options describe behaviors or misconduct (gender harassment and unwanted sexual attention), which aren’t categories of evidence sources.

So, when evidence is based on what individuals say about their own experiences or opinions, it’s testimonial evidence.
