How to think logically
Let us look at the question of logical thinking and contrast it to every other type.
Logic is a system of thought (and communication).
Logical thought (and communication) are different from all other types.
Logic is not guessing, nor wishing, or hoping.
Logic is a special kind of thought process, which is distinguished by the following characteristics:
- Logic is based upon facts, not feelings.
- Highly structured.
- Systematic, inductive and deductive.
- Self-consistent, (Coherent / non-contradictory).
- All key concepts have clear definitions.
- Logic is the method of reason.
"Fix reason firmly in her seat, and call to her tribunal every fact, every opinion. Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason, than that of blindfolded fear". Thomas Jefferson.
Structure your message like a tree
Knowledge is hierarchical in nature, or at least it should be.
Nature loves heirarchical branching structures.
This shape suggests that there are two fundamental ways of logical thinking: Analysis and synthesis.
- Analysis (is the act of mentally deconstructing a problem).
- Synthesis (is the act of mentally reconstructing solutions).
In any situation, we need to understand:
- What is the fundamental issue? (The trunk of the tree)
- What is NOT our fundamental issue? (This fact pertains to a different tree)
- What are the main subset elements? (Main branches)
- What are the minor subset elements? (Derivative branches)
- What are the details? (The leaves on the tree)
Common errors to not thinking logically
It is a common error not to think logically, for example:
- Failing to sort things into categories, sets and subsets.
- To think all on one plane, as if all the pieces were equally important.
- To act emotionally, without reference to logic.
- To be unstructured.
- To be disorganised.
- To be self-contradictory, (to say one thing and do another).
- To misidentify the fundamental issue.
- To focus on a trivial issue and therefore to miss the main point.
- To fixate on one thing to the exclusion of other parts of the system
- To concentrate on solving individual details, whilst ignoring their major causes. (Not recognising that the underlying cause of the leaves is the roots of the tree).

What are the painful long-term consequences suffered by anyone who is habitually illogical, unsystematic and disorganised?
What happens to their own work performance?
What is their effect on the others around them?
Problem Solving Training
Problem solving relies mainly on two forms of logic.
- Analysis: Deconstructing the logical structure of the problem
- Synthesis: Constructing Logical solutions.

logical thinking
Logical thinking is a work skill where you use facts to shape a clear, ordered line of thought. You split the issue into parts, rebuild answers in a tidy way, keep every step free from clash, and give each key idea one set meaning.
CG4D Definition
Context: Business
Genus: Skill
- Relies on facts, not feelings
- Follows a fixed, step-by-step structure that uses analysis and synthesis
- Keeps all steps self-consistent and clash-free
- Gives every key idea one clear meaning
Article Summary
Logical thinking is the skill of sorting facts, breaking a problem into clear parts, then building a reasoned answer; when you use this structured mix of analysis and synthesis, you avoid common errors and make faster, better choices.
