Thinking Outside the Box: How Unconventional Thinking Leads to Breakthroughs




We recently had a lively discussion on the radio about the fascinating concept of "unconventional thinking," or "assumption reversal."


What is "Unconventional Thinking"?

"Unconventional thinking," also known as Assumption reversal,  is a creative problem-solving technique. Proposed by American consultant Stephen Grossman, this method helps find solutions to problems that are difficult to solve with conventional approaches by intentionally adopting unconventional perspectives. For example, if we have the fixed idea that "hot pot dishes are for sharing with a group," then reversing that assumption to "there should be hot pot dishes for one person" is the basic principle of this method.


Steps to Unconventional Thinking:

This method consists of the following three steps:

  1. List existing assumptions and preconceptions: First, list existing "common sense" or "preconceptions." For example, "hot pot dishes are for sharing" or "being eco-friendly is troublesome." The key is to review assumptions we hold unconsciously.

  2. Reverse the assumptions: Next, flip those fixed ideas. For example, "hot pot dishes should be enjoyable by one person" or "being eco-friendly should be convenient and easy." Here, it's important to question conventional wisdom and encourage free thinking.

  3. Concretize the unconventional ideas: Finally, translate the reversed ideas into realistic plans. At this stage, temporarily set aside thoughts like "that's impossible" and refine the ideas from a new perspective. Bizarre ideas born from bold thinking can surprisingly transform into ideas that meet people's needs.


Unconventional Thinking and the SDGs?

On the radio, we had an engaging conversation about trying this "unconventional thinking" approach with the Sustainable Development Goals (SDGs). The SDGs present ideals that the entire world should strive to achieve, but these goals are sometimes so grand that many people wonder, "Are they even achievable?"

For example, consider the goal of "protecting life on land." If we dare to reverse this to "it's okay not to protect life on land," it might conversely clarify its importance and what we should originally aim for. Precisely because achieving the goals is difficult, incorporating unconventional perspectives can lead to new solutions and approaches.


Innovation Born from Unconventionality:

Unconventional thinking and assumption reversal are extremely effective methods for generating innovation. When bound by conventional perspectives, we can make improvements and refinements within existing frameworks, but it's difficult to generate entirely new ideas. As we discussed on the radio, innovation "doesn't exist on the extension of the existing," and unconventional thinking is required.


This method can be applied not only to business but also to our daily lives. For example, if we think a little unconventionally about things we normally consider "obvious" in our daily lives, we might find unexpected solutions. Small changes and reversals can open the door to new discoveries.
