How reliable are those tests that tell you what personality type you are?

Personality tests can provide insights into traits and preferences, but their reliability can vary significantly. Tests like the Myers-Briggs Type Indicator (MBTI) are popular but criticized for lacking scientific rigor and stability over time. While they may offer a general framework for understanding oneself and others, results should be taken with caution and not be used as definitive assessments of personality. Ultimately, individual differences are complex and cannot be fully captured by a single test.
