Human thinking has six levels of cognition:

The first is memory, which involves simply reciting and reproducing information; fundamentally, it is repeating other people’s viewpoints;
The second is understanding, which means being able to explain information in your own words, but it easily creates the illusion that you truly understand;
The third is application, meaning using existing knowledge to solve specific problems, yet it still mainly stays at the level of using tools;
The fourth is analysis, in which you begin to break down the structure of information, asking about logical premises, causal relationships, and implicit assumptions;
The fifth is evaluation, in which you weigh and judge among multiple reasonable but conflicting viewpoints, and take cognitive responsibility for your choices;
The sixth is creation, which involves recombining existing cognitive elements to form new viewpoints, structures, or solutions, thereby producing content that did not exist before.
So most people stay at lower levels of thinking not because they lack ability, but because the brain tends to think with minimal effort, and social media and identity recognition strengthen the habit of rapid reactions and repeating viewpoints; and to raise your thinking level, you need to slow down your responses, accept the discomfort of thinking, learn to confront contradictory information and make independent judgments, integrate and create on that basis, and continuously become aware of and correct your own thinking methods.
