Fluid intelligence refers to the capacity to think logically and solve problems in novel situations, independent of acquired knowledge. It is a key component of general cognitive abilities and is often considered to represent a person's reasoning capabilities in tasks requiring abstraction, pattern recognition, and problem-solving. When considering the average person's reasoning capabilities, fluid intelligence serves as a benchmark, reflecting the underlying cognitive processes that contribute to reasoning, such as the ability to analyze and work through new problems without reliance on previous knowledge or experiences. Thus, saying that fluid intelligence is the same as the average person's reasoning capabilities accurately captures the essence of these cognitive functions, indicating that fluid intelligence serves as a measure of those reasoning skills. This understanding stands in contrast to the other options, which either introduce concepts (like emotional decision-making) not directly tied to the definition of fluid intelligence, or suggest changes over time (such as a decrease with age) that do not align with the foundational concept of fluid intelligence as one aspect of reasoning capabilities.
