Personality tests are assessments designed to measure and evaluate an individual's personality traits, behaviors, and preferences. These tests often categorize people into different personality types or profiles, helping to understand how they think, feel, and interact with others. Common examples include the Myers-Briggs Type Indicator and the Big Five Personality Traits. These tests can be used in various settings, such as in the workplace for team building, in education for career guidance, or for personal development. While they can provide valuable insights, it's important to remember that results are not definitive and should be considered as one of many tools for self-discovery.
