Binet’s method focused on practical assessment of reasoning, problem-solving, and adaptive abilities, making it applicable for large groups. This is an important historical application of psychology often tested in PPSC exams, emphasizing how scientific research can be applied in practical, societal contexts. 10 PPSC-Relevant Facts: 1.
