Compare it with what the researchers have to say about 'intelligence'.
While common sense views intelligence as mental alertness, ready wit, and quickness in learning, researchers define it more comprehensively. Early theorists like Alfred Binet defined it as the ability to judge well, understand well, and reason well.
David Wechsler understood intelligence in terms of its functionality for adaptation to the environment. He defined it as the global and aggregate capacity of an individual to think rationally, act purposefully, and deal effectively with the environment.
Overall, researchers view intelligence as a global capacity to understand the world, think rationally, and use available resources effectively when faced with challenges. It involves the ability to understand complex ideas, adapt to environment, learn from experience, and overcome obstacles.
Explanation
The question asks to compare common sensical notions of intelligence with researchers' definitions. The answer highlights the shift from simple attributes like mental alertness to comprehensive psychological definitions by Binet and Wechsler, emphasizing rational thinking, purposeful action, and environmental adaptation.
