PMI Thinking Tool - Plus Minus Interesting

`

PMI Tool Description:

PMI Stands for Plus, Minus, and Interesting. When a poor thinker is asked to explore an idea or topic to write an essay, he/she writes the opinion first, and they try to support the opinion throughout the essay. There is no exploration on the subject because of the previously formed false opinion on that topic. I call it a false opinion because poor thinkers allow opinions and beliefs to form based on their first impression without careful exploration or evaluation of the subject. This tool protects you from forming false opinions by helping you to explore and evaluate an idea before attitudes and beliefs are formed.

Information -> Impression -> Opinion

Information -> Exploration -> Evaluation -> Opinion

When an average thinker is asked to explore a topic, she/he tend to think about the topic and come up with the list of points related to the topic. Then we try to group these points into Plus and Minus to come to a conclusion. During exploration of the topic, our thoughts move in many directions without focus leading to poor exploration and evaluation. This tool, sets the direction for our thinking, thereby improving the accuracy of the evaluation.

How To Use PMI Tool

PMI tool directs your attention towards one direction such that your mind taps most of the relevant information from your memory. First, look in the Plus direction and note down what you think(ignore and change your direction when you get any Minus points about the topic). Then, look specifically in the Minus direction and note down what you think. Finally, look in the Interesting direction. Interesting Points are comments, observations, ideas, etc. based on your feelings about the topic.

To evaluate the statement or topic, the scoring system is used on all the points. All Plus points get 0 to +5 points. All Minus points get 0 to -5 points. All Interesting points can vary from -5 to +5. After assigning scores, we can add up the score to find out the overall score. Based on the overall score we can decide our course of action.

By employing PMI Tool, your judgments will be based on the value of the idea rather than your emotions and gut feeling at that time.

Tips for using PMI tool:

  1. First, explore in Plus direction before moving on to Minus direction. It is psychologically difficult to think about positive points after exploring negative points of the topic.
  2. Doing PMI is not listing pros and cons as judgment intervenes exploration. When you judge whether the point is positive or negative, you are not using this tool effectively.
  3. Set fixed time duration for thinking in each direction.

When To Apply PMI Tool:

  1. To Explore Topic
  2. To Evaluate an Idea individually or group.
