Today, we will delve into a fascinating topic that’s as intriguing as it is pervasive: the Halo Effect. We’ve all experienced this cognitive bias, whether we’re aware of it or not.
Grab a cup of your favourite beverage, sit back, and embark on this enlightening journey together.

What is the Halo Effect?
The Halo Effect, first coined by psychologist Edward Thorndike, is our tendency to let one trait of a person or thing influence our overall perception of them. It’s like seeing that person or thing through “rose-coloured glasses” or perhaps a grimy fingerprint-covered pair.
For instance, if someone is well-dressed and reasonably good-looking, we might also perceive them as more intelligent, competent, or kind. It’s a shortcut our brains take to make sense of the world around us. But as we all know, shortcuts can sometimes lead us astray.

The Halo Effect in Business and Organisational Change
You might wonder, “What does this have to do with my role in designing experiences, events, and organisational change?” Well, quite a lot.
The Halo Effect can significantly impact our decision-making process, and being aware of it can help us make more balanced and objective decisions. Let’s say you’re planning a corporate event and must choose a keynote speaker. You might be inclined to choose a charismatic and engaging speaker, which are essential qualities. However, the Halo Effect might lead you to overlook other crucial factors, like the speaker’s expertise or relevance to the event’s theme or general cultural alignment with the audience.
By being aware of the Halo Effect, you can ensure you’re making a well-rounded decision. Similarly, the Halo Effect can cloud our judgment when designing organisational change. We might be swayed by a leader’s charisma and overlook potential flaws in their proposed changes. Or we might be so enamoured with a successful company that we try to replicate their strategies without considering if they’re the right fit for our own organisation.
Mitigating the Impact of the Halo Effect But fear not, dear reader. Awareness is the first step towards mitigating the impact of the Halo Effect. By recognising this cognitive bias, we can take steps to counteract it. We can make a conscious effort to separate our impressions of individual traits from our overall judgement. We can seek diverse perspectives to get a more balanced view. And we can foster a culture of open communication where biases can be called out and discussed.

How might we take steps to address the Halo Effect?
- Seek Diverse Perspectives: Actively involve multiple individuals in decision-making processes to gather various opinions and reduce the influence of one person’s characteristics.
- Use Structured Evaluation Criteria: Create a standardized set of criteria for evaluating individuals or products, ensuring that each assessment is based on objective measures rather than subjective impressions.
- Blind Assessments: Whenever possible, conduct evaluations without knowing the identity or background of the subjects. This can help focus on performance rather than personal attributes.
- Awareness and Training: Educate yourself and your team about the halo effect and other cognitive biases. Awareness can help individuals recognize when non-relevant factors might influence them.
- Regular Reflection and Review: Periodically review decisions and judgments to identify any potential biases that may have influenced the outcome and adjust future evaluations accordingly.
By implementing these strategies, you can significantly reduce the impact of the halo effect on your assessments and decisions. If this sounds too big of a challenge for you and your team, bring in expert change management and experience design consultants to help you navigate the challenging conversations.

Let’s Continue the Conversation So, the next time you find yourself being swayed by a charming speaker or a successful company, take a moment to check for the Halo Effect. Remember, not everything that glitters is gold. Now, I’d love to hear your thoughts on the Halo Effect.
