Convergent and divergent thinking skills are both aspects of intelligence and critical thinking.

Convergent Thinking is the bringing facts and data together from various sources and then applying logic and knowledge to solve problems or achieve objectives.

The deductive logic that the fictional character Sherlock Homes used is a good example of convergent thinking. Gathering various tidbits of facts and data he was able to put the pieces of a puzzle together and come up with a logical answer to the question: Who done it?

Divergent Thinking is thinking outwards instead of inward. It is the ability to develop original and unique ideas and then come up with a problem solution or achieve an objective.

Einstein was a strong divergent thinker. He asked simple questions and then did mental exercises to solve problems. For example, as a young man Einstein asked himself what it would be like to ride on a beam of light. It took him many years of thought experiments, however the answer helped him develop the special theory of relativity.

Standard IQ tests gauge convergent thinking. Pattern recognition, testing knowledge, logic thought flow and the ability to solve problems can all be tested and graded.

There are no accurate tests able to measure divergent thinking skills. It’s not surprising that creative skills can’t be tested.

How would one construct a test to determine divergent thinking capabilities? Did Leonardo da Vinci’s creation of the Mona Lisa take more brain power than Einstein’s equation E= MC²? Is the design of the Opera house in Sydney Australia more creative than Margaret Mitchell’s novel Gone with the Wind? Is Alvin Toffler’s book Future Shock more inspired than Salvador Dali’s painting of the melting clocks?

Who’s to say which of these examples is more creative? Does public opinion decide what how much creativity was required for something, or is in the eye of the beholder?

These are interesting philosophical questions, and ones that are enjoyable to talk about at parties, however aren’t useful to discover how to creatively think.

A more useful question is: How can convergent and divergent thinking be improved and utilized to strengthen your critical thinking skills? Convergent and divergent thinking skills are both important to critical thinking. Not only that, they are interrelated.

Deductive reasoning looks inward to find a solution, while divergent reasoning looks outward for a solution. Following the facts and data to determine the answer to a problem is not significantly different than having a spark of a thought and then coming up with a solution. Some of the same mental processes are used. Both require critical thinking skills to be effective. Both are used for solving problems, doing projects and achieving objectives.


In other words, Convergent and Divergent thinking skills are two sides to the same coin—of critical thinking. One without the other doesn’t make sense. Both start with asking simple questions from a curious mind. Both can be strengthened by an insatiable curiosity and strong willingness to learn about the world and the people in it. Here is an example.
