The graphic above illustrates that LOGIC takes place primarily in the LEFT-FRONT region of the cerebral cortex. The cortex is the thinking part of the brain. The LEFT side uses language as a system for storing and sorting information. So thinking on the left side is sequential, systematic and objective. The FRONT part of the left brain takes data from the back part—information such as names, numbers and definitions—and draws logical conclusions.

For example, when you consider the words "chair" and "table," you know they're related. They're both part of the larger concept of "furniture."

LOGIC is the mindframe of problem solving. It enables you to:

  • Analyze the significance of data
  • Discover trends in facts and information
  • Do research using scientific methods
  • Evaluate current assumptions
  • Make a new assumption
  • Think of a reason why something happens
  • Decide which formula or principle applies to a given situation
  • Predict a future event based on a cause-and-effect principle
  • Draw conclusions based on evidence
  • Examine evidence to verify whether a conclusion is supported by the facts
  • Use a proven principle as a guideline
  • Use data to compare the pros and cons of several options
  • Use critical judgment to decide what to do
  • Set a goal to fulfill a purpose
  • Design a strategy to achieve a goal
  • Create an action plan to implement a strategy

LOGIC is concerned with "connecting the dots" step by step to make sense of information. When you think about the measurement, "3 degrees below zero," you compare it to other measurements and your personal experience. Using logic, you reason that this is a cold temperature, cold enough to cause ice and snow.

LOGIC seeks the answers to questions such as, "Is this realistic?" "Why did this happen?" and "How does this work?" For instance, a friend tells you that if you always turn off the engine of your car at stoplights, you can improve your gas mileage. You decide to test the technique. You already know that your car has been averaging 31.5 miles per gallon. After two months of calculating your mileage, your new average is 30.5 miles per gallon. You decide that your friend was wrong. This conclusion is the result of logical thinking.

LOGIC is a key mindframe for engineers, doctors, lawyers, legislators, planners, and programmers. The ability to reason is also crucial to conducting scientific research, managing money and writing reports. It allows you to apply principles and solve problems. When you examine evidence and draw conclusions, the knowledge you gain is grounded in reality.

These instances show the logical part of your mind at work, performing critical and intellectual thinking tasks. What role does the LOGIC mindframe play in your thinking?
