The American psychologist Joy Paul Guilford (1897-1987) introduced
the terms divergent and convergent thinking in 1946. The divergent and convergent thinking are two natural
forms of thinking (two sides to the same coin) that produces solutions to problems
(production type of thinking). “Convergence”
refers to thinking that leads to a single correct solution. “Divergence” refers to thinking that
leads to number of correct solutions. Both divergent and convergent thinking
are necessary for problem solving, decision making, creativity and innovation. Divergent
thinking is used to create ideas and convergent thinking is used to judge
ideas. Convergent thinking is opposite of divergent thinking. In divergent
thinking, one thought stimulates many others and the thinking branches or
broaden out (multi-directional thinking).
In convergent thinking, many thoughts are reduced to a single one and the
thinking funnels in (linear thinking).
In divergent thinking, a problem can be solved with different approaches
whereas in convergent thinking, there is one answer for any given problem. Divergent
thinking is generating options without judgement and convergent thinking is
judging the options.
Creativity
= “diverge before you converge
Creativity = Divergent thinking (“thinking up
ideas”) + convergent thinking (“assess the effectiveness of the ideas”)
Creativity = Generating many ideas +
converging on the best idea
Definitions and
explanations
Convergent thinking is the ability to apply logic and
knowledge to narrow down the number of possible solutions to a problem.
Convergent thinking is more rigorous and analytical and is associated with
focused attention. Consideration,
improving and fine – tuning of ideas are part of convergent thinking. Convergent
thinking focuses on ‘screening, selecting and evaluating alternatives’ (Puccio
et al. 2006). The goal of convergent thinking is to find the one correct answer
or the best answer of the options available.
Divergent thinking is the ability to think along many paths
to generate many solutions to a problem. Brain storming is a typical example of
divergent thinking. Divergent thinking is essentially open-ended thinking
involving non-logical processes which allows using one’s imagination to explore
all sorts of new possibilities. The goal of divergent thinking is to come up
with many possible solutions, answers or options. Divergent thinking typically
occurs in a spontaneous, free-flowing manner and many ideas are generated in a
random, unorganized fashion. J.P. Guilford (1950, 1967) described divergent thinking
as a primary method of achieving creative ideas.
Divergent thinking à thinking
outwards—centrifugal movement-- broad focus of attention—less goal bound—gathering
diverse points of view—suspending judgement-- idea generation—creative process.
Convergent thinking à thinking inwards –centripetal movement--narrow focus of attention –more goal bound -- sorting ideas into categories—exercising judgement – idea analysis—evaluative process.
Convergence and
divergence
Convergence means bringing together and moving toward one
point. Divergence means developing in different directions. Divergence is a
mode of thinking in which one uses the right brain to explore ideas or
solutions without judging them. In convergence thinking mode one uses the left
brain to analyse ideas and think them through logically. Convergence and divergence are two necessary
types of thinking for being creative. In any problem solving situation from the
beginning to the end, individuals are shifting their thinking modes between
divergence and convergence. The ability to switch from one type of thinking to
other is called pivot thinking. Pivot
thinking is a cognitive problem solving style that easily pivots or shifts between
divergent or convergent problem solution possibilities. One of the key
indicators of an innovative process is the alternation between divergent and
convergent thinking modes of thinking with frequent pivots between the two
modes. A “converger” would tend to
prefer convergent problem solving techniques while a “diverger” would tend to favour divergent problem solving
techniques. A “pivot thinker” would
display problem solving preferences that easily pivots or shifts between
divergent and convergent approaches.
Rules of divergent
thinking
A divergent thinking involves imaging, reframing and seeing
issues from different perspectives. Divergent thinking is complex, associative
process of bringing alternative, novel, and original ideas to emergence.
Divergent thinking allows one’s imagination to produce variability and
encourages the production of multiple answers. It involves thinking laterally,
not just in or convergent ways. Divergent thinking usually occurs in a
spontaneous, free-flowing and non-linear manner. Einstein was a strong
divergent thinker. The strategies for encouraging divergent thinking include
brainstorming, keeping a journal, free- writing and mind mapping.
1. Expand ideas and defer judgement
2. Create and accept plenty of ideas
3. Combine ideas and consider novelty
4. Break paradigms and generate strange ideas.
Commandments of
divergent thinking (M.D. Jones)
- The more the ideas, the better – “Quantity breeds quality.”
- Build on other ideas –expand the range of options, perspectives and elements.
- Seek wild and unusual ideas –wacky ideas incite humour and open up many paths.
- Don’t evaluate ideas – suspend judgment.
- Fluency –generating many ideas.
- Flexibility – generating different types of ideas.
- Originality – generating novel ideas.
- Elaboration – building on and developing ideas.
Convergent thinking
processes move from data, clues or parts of a problem to a specific idea. Convergent
thinking involves analysis of ideas and synthesis in to concepts, evaluation
and prioritization of concepts. Convergent thinking narrows down a large number
of ideas through the process of analysing, sorting, judging, eliminating and
selecting (directed thinking). Convergent
thinking emphasizes accuracy, correctness and effectiveness. In convergent
thinking, there is usually one conclusion or answer that is regarded as unique
and thinking is channelled or controlled in the direction of that answer.
Convergent thinking allows us to use our knowledge to examine concepts.
Convergent thinking is particularly appropriate in science, maths and
technology. Convergent thinking is essentially about traditional problem
solving.
- Be systematic and analyse the objectives
- Evaluate the ideas using rules of logic
- Use intuition
- No paradigm breaking and draw a best answer.
Advantages
Convergent and divergent thinking
skills are both important to critical thinking. Convergent and divergent
thinking tools are extremely helpful when making decisions. Creative
achievement requires a complex combination of both divergent and convergent
thinking. In the generation stage, teams or individuals use divergent thinking
to develop novel ideas. In the application stage, they use convergent thinking
to make those ideas useful. Divergent thinking is the wellspring of invention.
In academic settings, when a student takes a multiple choice exam, he tries to
find out the right answer from a set of incorrect options. Most training in schools
encourages convergent thinking.
