Linear Thinking Bias

by

Last updated: August 8, 2018

When assessing the validity of problem solutions, we regard them as more valid if their discovery stories are logical, than we would if they're other than logical. This can lead to erroneous assessments, because the discovery story is not the solution.
Srinivasa Ramanujan

Srinivasa Ramanujan (1887-1920) was an Indian mathematical genius, self-taught, who exploded onto the mathematical scene in 1913. He became a research scholar at Cambridge in 1914, where he was mentored by and collaborated with G.H. Hardy. He received a Bachelor of Science degree, later renamed PhD, in 1916. His genius was so extraordinary that he repeatedly encountered linear thinking bias.

Of the many ways of thinking about problem-solving methods, the linear/non-linear model, as widely understood, is perhaps the most linear. Linear thinkers are said to use thought processes dominated by logic and evidence. They follow a step-by-step progression in which the problem solver uses evidence and reason to move logically from starting point to solution. For example, linear approaches to complex problems often use analysis and synthesis. They decompose the larger problem into pieces, find solutions to the pieces, and then recombine the solutions, claiming (or, at least, hoping) that the combination of solutions to the pieces is a solution to the combination of the pieces. Linear thinkers seek basic facts, assumptions, or drivers, and a small set of laws that then predict whole-system behavior.

Non-linear thinkers are more likely to accept that complex problems aren't susceptible to analysis and synthesis. They're more likely to try to understand the whole, working from multiple starting points. They collect and sort through known patterns, connections, and insights. Then they apply them to find new patterns, connections, and insights. They recognize that the system might not be reducible to a few core elements governed by a few simple rules. Non-linear thinkers are more likely to accept — and seek — explanations for how the system itself drives the system.

But widely accepted explanations of non-linear thinking take different views of non-linear thinking. In these explanations, non-linear thinkers are said to search for solutions by striking out in various directions, sometimes selected at random or by whim, from multiple starting points. Then, so it is said, they apply logic and evidence to expand from wherever they are to wherever they can go.

A difficulty inherent in this model Some models of non-linear
thinking describe it as
essentially piecewise linear
of non-linear thinking is that it is essentially piecewise linear. It models non-linear thinking as a sequence of linear forays into the unknown, from randomly chosen starting points, without necessarily applying to the next part of the exploration any of the knowledge gained from parts previously explored.

When we ask non-linear thinkers how they found the problem solution they just presented, they might not have a "logical" explanation, especially if they found their solution by other than logical means. Often, the absence of a logical, evidence-based discovery story causes some to doubt or even reject the non-linear thinker's results. This is what I call linear thinking bias. After a number of such experiences with linear thinking bias, some non-linear thinkers learn to retroactively invent linear discovery stories, sprinkled with appropriate amounts of evidence and logic, to explain to others how they discovered their results.

When this happens, the truth of their discovery method remains hidden. So, too, does a larger truth: we are all, to varying degrees, non-linear thinkers. Don't ask me how I figured that out. Go to top Top  Next issue: Counterproductive Knowledge Workplace Behavior: II  Next Issue

The Power Affect: How We Express Our Personal Power

Many The Power Affect: How We Express Personal Powerpeople who possess real organizational power have a characteristic demeanor. It's the way they project their presence. I call this the power affect. Some people — call them power pretenders — adopt the power affect well before they attain significant organizational power. Unfortunately for their colleagues, and for their organizations, power pretenders can attain organizational power out of proportion to their merit or abilities. Understanding the power affect is therefore important for anyone who aims to attain power, or anyone who works with power pretenders. Read more about this program.
