*Intellectual skills* are defined as the methods that an individual can use to evaluate or organize information and data. In the 1950s, educational psychologist Benjamin Bloom created a model of intellectual skills that defined abilities such as application, analysis and synthesis as building on basic knowledge; since then, different psychologists have used multiple models and approaches to understand intellectual skills. However, a few types of skills, such as problem solving, are commonly used in a wide variety of intellectual disciplines.
Knowledge and Understanding
In Bloom's system, known as *Bloom's taxonomy*, the most basic forms of intellectual skills were defined as *knowledge* and *comprehension*. Knowledge is defined as the ability to memorize and reproduce information. Comprehension builds on knowledge and is the ability to understand what memorized information means. For example, memorizing that two plus two equals four is a use of knowledge as a skill. However, knowing that two of an object plus two of an object equals four of an object is comprehension -- understanding what the parts of the formula mean.
One commonly recognized intellectual skill is *critical thinking* -- the ability to analyze and interpret information to assess its context and validity. This can include multiple specific skills: asking questions about information, comparing material to known information and drawing connections between information and its context to analyze it -- for instance, to check for bias. Some psychologists connect critical thinking to an additional intellectual skill, sometimes referred to as *disinterested scholarship*: the ability to distance oneself from material or information being presented to evaluate its validity.
Another set of intellectual skills is *problem solving*. Where critical thinking involves analyzing and evaluating information, problem solving involves an individual using intellectual skills to solve situations she is not familiar with. Psychologists have connected multiple intellectual skills to problem solving: analyzing the problem, using information to come up with potential solutions and testing solutions empirically. Other skills related to problem solving include setting goals and planning different ways to approach the problem. In each case, these skills involve relating the information of the problem to multiple sets of known information and finding a way to creatively synthesize that information with the problem; this makes problem solving once of the most complex forms of intellectual skill.
While problem solving and critical thinking involve using intellectual skills to understand and solve exterior information, intellectual skills can also be used creatively. In fact, some 21st century education psychologists have modified Bloom's taxonomy to show *creating* as the most developed intellectual skill. Different intellectual skills connected with creativity involve planning, synthesis -- combining multiple sources of information -- and *fluency*, the ability to create quickly from limited information. Originality, the skill to create distinctive solutions, and flexibility, the skill to alter and revise information given changing circumstances, are also important skills in the creative process.
