Ladder of Inference: The Definitive Guide

Ladder of Inference
The Definitive Guide

Have you ever found yourself in a situation where you have been misunderstood and left wondering why someone else has interpreted something you said or did, and put a meaning on it that you never intended? Or have you ever been accused of jumping to conclusions? 

Then chances are you have been climbing the ‘Ladder of Inference’ too fast.

The Ladder of Inference is a theory that implies every person has a different perspective and understanding of the same given situation.

Understanding your own and others’ "Ladder of Inference" can help us make better decisions and also help evaluate the quality of a decision.

In this article, I will explain the Ladder of Inference in more detail, and show how you can use it.

So if you want to:

• Avoid jumping to conclusions
• Catch yourself before you act out of bias  
• Save yourself from unwise choices.
• Avoid falling prey to confirmation bias.
• Take appropriate fact-based action.

You’re going to find this guide super useful!

I have put together well-researched tips in this guide so that you can avoid jumping to conclusions.

The Fundamentals of Ladder of Inference

What is the Ladder of Inference?

​​The Ladder of Inference is a mental model describing how we move from a piece of data through a series of mental processes to reach conclusions and take actions. It highlights how we select data, make assumptions, and draw conclusions that reinforce our existing beliefs. 

The Ladder Of Inference provides a 7-step process, just like the steps of a ladder, that we use to make sense of situations to act. It describes the thinking process that we go through, usually without realizing it, to get from a fact to an assumption and action.

What is the origin of the Ladder of Inference?

The Ladder of Inference was developed by the American organizational psychologist Chris Argyris, a former professor at Harvard Business School, in 1970. Argyris developed the “Ladder of Inference” to describe how people form and sustain mental models. According to Argyris, people make assumptions in their daily lives. Those assumptions are necessary. 

However, these assumptions could be wrong, especially when these assumptions are about the intentions or beliefs of others. In 1992, the Ladder of Inference became popular after being described in the bestseller The Fifth Discipline: The Art and Practice of the Learning Organization, by American scientist Peter M. Senge.

History of Opinion-forming Models

To understand the ‘Ladder of Inference,’ in its entirety we must understand the prominent theories which were precursors to the model and also get an understanding of similar theories which are often confused with the Ladder of Inference.

Fixation of Belief- Charles Sanders Pierce

One of the earliest research on opinion formation was done by American philosopher and mathematician Charles Sanders Peirce.

In his 1887 article, titled “The Fixation of Belief,” Peirce introduced the process by which he observed how individuals hold beliefs and opinions. Pierce identified and defined four basic methods people use to fixate on their beliefs.

1. Method of Tenacity: Individuals resist other principles, opinions, viewpoints, dogmas, or attitudes that challenge their belief and waste no time in trying to make up their mind. 

2. Method of Authority: Individual looks up to a figure such as an individual or institution he or she deems as an authority to determine which beliefs they are going to accept.

3. Method of Taste: Individual chooses principles, opinions, viewpoints, dogmas, and attitudes that sound good to him or them or that could bring forth personal benefits. 4.

4. Method of Science: Individuals accept an assumption as true for the simplest reason that it sounds logical or reasonable, although it remains untested or unproven.

Abstraction Ladder- Hayakawa

The Ladder of Abstraction was created by linguist S. I. Hayakawa. It is a mode to understand how people think and communicate. In ‘Language in Thought and Action’, published in 1939, he explained how the ladder of abstraction works. 

His theory argues that humans can reason at four language levels ranging from concrete words to abstract words. The concrete words are the base of the ladder and the abstract words are at the top of the ladder.

The higher up one goes on the ladder, the more abstract the idea, language, or thought becomes and the lower one goes on the ladder the more concrete the idea, language, or thought becomes.

For instance, if you stay on the top of the ladder, you will end up just talking of concepts that aren’t backed by any fact. On the other hand, if a person is on the bottom of the ladder, he/she will end up only talking about facts and not explaining them. 

Both scenarios are ineffective while communicating. That is why understanding the Ladder of Abstraction and finding your balance on the ladder becomes critical.

Four Rungs of Hayakawa’s Ladder of Abstraction

Level 1- Specific, (Concrete words)

The first level of the ladder is concrete words. These sit at the bottom of the ladder. These are less complex and very concrete words defining people, things or places.

Examples: the Channel 5 perfume, BLT sandwich, a Tesla car, the Traveller’s Palm plant, etc.

Level 2- Definite groups

The second rung of the ladder consists of words that are less concrete and little more abstract. 

Examples: house plants, perfumes, sandwiches, electric cars, etc.

Level 3- Broad groups
