Cognitive biases are psychological phenomena that distort our perceptions, memory, or judgment. When success depends on accurate perception, evaluation, or recollection of what's around us, distortions can lead to erroneous results that range from harmless to catastrophic.
The Halo Effect (or Halo Error) was first identified in 1920 by Edward Thorndike, who was studying how military officers evaluated their subordinates [Thorndike 1920]. He found that high (low) ratings in one attribute tended to be correlated with high (low) ratings in other seemingly unrelated attributes. But the effect is universal, extending beyond military performance evaluation. In modern experiments, for example, researchers have demonstrated that people tend to judge physically attractive people as possessing more socially desirable personality traits than do less physically attractive people. Thus physical traits bias our assessment of personality traits.
In the context of performance reviews, researchers have demonstrated that when evaluators perceive in subordinates attributes that they regard as negative, those evaluators tend to assess more negatively the unrelated attributes of those subordinates.
The Halo Effect is pervasive. Here are three examples of how it can affect organizational decision-making.
- Status affects persuasiveness
- Assessments of the validity of someone's assertions can be affected by our perception of her or his status. For instance, when supervisors attend meetings of their subordinates, their statements tend to have greater weight than they deserve. And when pariahs speak, listeners are more likely to discount what is said than when superstars deliver essentially the same message.
- The effects of status are wide-ranging. For instance, someone mentored by a high-status individual can acquire some of the elevated status of the mentor. See "Dispersed Teams and Latent Communications," Point Lookout for September 3, 2003, for more.
- Falsifying an argument falsifies the assertion
- When we assess the truth of an assertion, we examine the argument that justifies it. In the course of that examination, if we find a flaw in the argument, we sometimes conclude that the assertion is false. The assertion might indeed be false, but finding a flaw in a supposed proof of the assertion doesn't prove that the assertion is false.
- This error is a rhetorical fallacy known as argumentum ad logicam, the fallacy fallacy, or the fallacist's fallacy. It's a manifestation of the halo effect in the realm of logic.
- Hat hanging
- Hat hanging is a phenomenon identified by Virginia Satir, a pioneer family therapist. When pariahs speak, listeners are
more likely to discount what is
said than when superstars deliver
essentially the same messageThe name evokes the idea that we hang the hat of someone from our past on someone in our present. For example, life can be difficult for someone whose appearance matches the appearance of a film actor who often plays villains. It's a manifestation of the halo effect in the realm of personal identification.
- Hat hanging can occur in supervisor-subordinate pairs when age differences approximate parent-child age differences. See "You Remind Me of Helen Hunt," Point Lookout for June 6, 2001, for more.

More articles on Critical Thinking at Work:
- Inner Babble
- It goes by various names — self-talk, inner dialog, or internal conversation. Because it is so
often disorganized and illogical, I like to call it inner babble. But whatever you call it, it's
often misleading, distracting, and unhelpful. How can you recognize inner babble?
- Wishful Significance: I
- When things don't work out, and we investigate why, we sometimes attribute our misfortune to "wishful
thinking." In this part of our exploration of wishful thinking we examine how we arrive at mistaken
assessments of the significance of what we see, hear, or learn.
- Patterns of Conflict Escalation: II
- When simple workplace disagreements evolve into workplace warfare, they often do so following recognizable
patterns. If we can recognize the patterns early, we can intervene to prevent serious damage to relationships.
Here's Part II of a catalog of some of those patterns.
- Wacky Words of Wisdom: V
- Adages, aphorisms, and "words of wisdom" are true often enough that we accept them as universal.
They aren't. Here's Part V of some widely held beliefs that mislead us at work.
- The Paradox of Carefully Chosen Words
- When we take special care in choosing our words, so as to avoid creating misimpressions, something strange
often happens: we create a misimpression of ignorance or deceitfulness. Why does this happen?
Forthcoming issues of Point Lookout
- Coming May 23: Narcissistic Behavior at Work: IX
- An arrogant demeanor is widely viewed as a hallmark of the narcissist. But truly narcissistic arrogance is off the charts. It's something beyond the merely annoying arrogance of a sometimes-obnoxious individual. What is narcissistic arrogance and how can we cope with it? Available here and by RSS on May 23.
- And on May 30: Chronic Peer Interrupters: I
- When making contributions to meeting discussions, we're sometimes interrupted. Often, the interruption is beneficial and saves time. But some people constantly interrupt their peers or near peers, disrespectfully, in a pattern that compromises meeting outcomes. How can we deal with chronic peer interrupters? Available here and by RSS on May 30.

- Technical Debt Management: Making the Business Case
- This program
outlines the steps necessary for deploying a program for rational management of technical debt. For
many organizations, adopting a program for rationally managing technical debt entails organizational
change. And unlike some organizational changes, this one touches almost everyone in the organization,
because technical debt isn't merely a technical problem. Technical debt manifests itself in technological
assets, to be sure, but its causes are rarely isolated to the behavior and decisions of engineers. We
can't resolve the problem of chronically excessive levels of technical debt by changing the behavior
of engineers alone. Technical debt is the symptom, not the problem. In this program we outline the essential
elements of an effective business case for adopting a rational technical debt management program. But
this business case, unlike many business cases, cannot be captured in a document. We must make the case
not only at the leadership level of the organization, but also at the level of the individual contributor.
Everyone must understand. Everyone must contribute. We explore five issues that make technical debt
so difficult to manage, and develop five guidelines for designing technical debt management strategies
for the modern enterprise. Read more about

- The Race to the South Pole: The Power of Agile Development
- On 14 December 1911, four men led by Roald
Amundsen reached the South Pole. Thirty-five days later, Robert F. Scott and four others followed. Amundsen
had won the race to the pole. Amundsen's party returned to base on 26 January 1912. Scott's party perished.
As historical drama, why this happened is interesting enough. Lessons abound. Among the more important
lessons are those that demonstrate the power of the agile approach to project management and product
development. Read more about this program. Here's

- The Power Affect: How We Express Our Personal Power
- Many people 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.
