The Halo Effect

by

The Halo Effect is a cognitive bias that causes our evaluation of people, concepts, or objects to be influenced by our perceptions of one attribute of those people, concepts, or objects. It can lead us to make significant errors of judgment.
Two halos: the Ring Nebula and a solar halo

Two halos: the Ring Nebula (top) and a solar halo (bottom). The Ring Nebula (Messier 57) is a shell of ionized gas that surrounds a white dwarf star following an explosion of a red giant star. The shell is actually spherical, but it appears to us to be a ring because from this angle its edges are thickest. The solar halo is a fairly common sight that occurs when high thin clouds are positioned between the sun and the viewer. The clouds consist of tiny ice crystals oriented randomly, and rotating and moving randomly, but a tiny fraction of them at any one time are oriented just right to reflect and refract solar light at an angle of about 22 degrees. Thus the angle between the line to the sun and the edge of the halo is exactly that angle.

These two halos are of fundamentally different kinds. The atoms of the Ring Nebula actually emit light. The ice crystals of the high thin clouds that produce the solar halo are reflecting and refracting light, the source of which is elsewhere (in this case, the sun). The Ring Nebula is an active halo, the solar halo is a passive halo. The ionized gases of the Ring Nebula are primary sources of light. The ice crystals of the solar halo are secondary sources of light. In the Halo Effect, the halo in question is passive. That is, when evaluating people, ideas, or objects, there are two kinds of attributes in question. The attributes we know and understand are the primary sources. The other attributes — the ones we get confused about — are the secondary sources. Photos of the Ring Nebula and the solar halo courtesy U.S. National Aeronautics and Space Administration.

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. 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 attractive people as possessing more socially desirable personality traits than do less 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 message
The 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.

Conflict Resolution Skills for Leaders
ConflConflict Resolution Skills for Leadersict is inherent in collaborative work. When conflict is constructive, it produces better outcomes. When it's destructive, it can be an insurmountable obstacle to success. In this program, we explore the connections between the outcomes of collaboration and conflict in both of its forms. And we emphasize the skills needed most by leaders. The leader's task is to manage conflict so as to ensure that the group achieves its objective with its capacity to collaborate intact, or even enhanced. Rick Brenner shows team leaders and team sponsors the techniques they need to manage team conflict for relationship safety and better outcomes. Read more about this program.

Strategies for Leading Teams in Hard Times
When Strategies for Leading Teams in Hard Timesa project team is on task, the contributions of leaders are important, and little noticed. Sometimes the team encounters unexpected difficulty, or requirements change, or budgets are reduced, or any of a number of other things might happen. In these cases, the leader must make or facilitate decisions about how to respond or how to revise the plan. We get through it somehow. Hard times are something else altogether. Despondency, disillusionment, resource shortages, unexpected and severe failure of the plan, and toxic conflict can erode morale. How can leaders deal with such situations?

Strategies for Technical Debt: A Workshop for Enterprise Leaders
TechnTechnical Debt Management for Enterprise Leadersical debt is more than mere IT jargon. It's a metaphor that refers to the accumulation of technical artifacts that really ought to be retired, replaced, rewritten, re-implemented, or, if absent, created. We can find technical debt in almost any system, including those that seem to be working well. So what's the problem? The problem is the "interest charges." Systems carrying technical debt are more difficult to maintain, more difficult to extend or enhance, and more difficult to use, than they would be if we "retired" the debt. This engaging and eye-opening program points the way to a path that leads your organization out of technical debt, to make it more adaptable, more transformable, and more agile.

Creating High Performance Virtual Teams
Many Creating High Performance Virtual Teamspeople experience virtual teams as awkward, slow, and sometimes frustrating. Even when most team members hail from the same nation or culture, and even when they all speak the same language, geographic dispersion or the presence of employees from multiple enterprises is often enough to exclude all possibility of high performance. The problem is that we lead, manage, and support virtual teams in ways that are too much like the way we lead, manage, and support co-located teams. In this program, Rick Brenner shows you how to change your approach to leading, managing, and supporting virtual teams to achieve high performance using Simons' Four Spans model of high performance.
