👉 The Myers Fluid Intelligence (MFI) scale, part of the broader Myers-Briggs Type Indicator (MBTI), measures an individual's ability to think abstractly, reason flexibly, and solve problems in novel situations, often referred to as fluid intelligence. Unlike crystallized intelligence, which relies on accumulated knowledge and experience, MFI assesses cognitive processes that are not tied to specific learned information but rather to the capacity for mental agility and adaptability. This fluid intelligence is crucial for tasks that require innovative thinking, pattern recognition, and quick decision-making, making it a key component in understanding cognitive flexibility and problem-solving capabilities.
