FROM THE CREW

Hey 👋 The Crew here.

Whenever you get negative feedback for a product or service, just remember that at least nobody took time and effort to inscribe it on a small clay tablet.

In case you didn’t know, that is the oldest customer complaint to this date—and is written to a copper trader by a customer dissatisfied by the product quality, but also by the treatment of his servant.

Guess the trader should’ve invested in better customer support at least…

PSYCHOLOGICAL EFFECT

Halo effect

In 1920, psychologist Edward Thorndike asked a group of military officers to evaluate their subordinates based on nothing but their own impressions.

He found that if an officer perceived a soldier as physically attractive or strong, they tended to also rate them highly on unrelated traits like intelligence and leadership.

He called this phenomenon The Halo effect, and it’s a cognitive bias where our overall impression of a person, product, or brand is influenced by a single trait or characteristic.

It’s also why we say that first impressions matter, for example.

Assuming they have equal skillsets, think about who’s more likely to get a job—a well-dressed, charismatic, kind candidate, or a dumpster fire of a person. It’s cruel, but it’s psychological, and even primal.

The Halo effect is one of the most popular and frequently studied biases, especially among marketers.

So let’s see how you can leverage it for better results.

Three ways to leverage Halo effect

1) Build brand reputation from multiple angles

Imagine Apple suddenly announced a toaster. What would your first impression be?

A lot of people might think it’s going to be a super cool, “smart” toaster that will toast bread like no toaster before—without even trying it.

… Because Apple built its reputation on innovative, premium, user-friendly products. That reputation carries over.

Also, nowadays, you see most e-commerce merchants opting for Shopify simply due to their reputation of helping businesses launch and maintain their online stores without a fuss.

Here’s how you can leverage your brand touches to create a positive Halo effect:

  1. Be consistent across all touchpoints. Every interaction should reinforce the same core values. If you’re positioned as luxurious, everything from packaging to customer service to web design should feel premium.
  2. Leverage thought leadership or social proof. Get endorsements from respected figures in your industry, share success stories, and case studies.
  3. Maintain a strong identity. Your branding should be recognizable, both visually and verbally. Think of how Nike is synonymous with the “Just do it” slogan and associates their customers with motivation and performance.

All this can help form a positive reputation in your customers’ minds that will help with acquisition.

2) Prime your brand or product for a winning first impression

As we said, first impressions shape lasting perceptions in a single moment.

The Halo effect kicks in the second someone interacts with your brand—whether it’s your website, packaging, or even customer service.

A sleek, well-designed interface makes a SaaS product seem more powerful. A friendly, professional salesperson makes a service feel more trustworthy. And so on…

A good onboarding can make your entire SaaS feel like the real deal before users even start serious work.

Strava, an exercise tracking app, immediately guides you through a tour of every feature—making you feel like the app has no major flaw:

Truth be told, are there any?

3) Avoid the “Horn effect”

Thorndike, who coined the term Halo effect, also coined a term for the opposite: The Horn effect.

It’s a bias where one negative trait creates the belief that something or someone must have more negative traits.

In the case of your brand, one slip can cause irreparable damage.

One of the most obvious examples today is probably Tesla. And you can guess why…

Most people associate the car brand with Elon Musk. And while the company itself makes innovative products, Musk’s controversial presence might make many potential customers back away.

The same goes for X, which many brands still avoid advertising on.

But sometimes, a simple update like a price hike can create a negative impression. Evernote, a note-taking app, doubled its pricing in 2023—infuriating users and causing a mass exodus.

The takeaway: One major mistake, like a security flaw, bad UX change, pricing controversy, or even something a CEO did irrelevant to the product itself can overshadow years of good work.

Public perception sticks, even after fixes.

So make sure you test any feature on a good enough sample, invest in social listening, always ask for feedback, and stray away from controversy.

… Unless the right controversy would put your brand in the right limelight, creating a Halo effect.

GOOGLE: Uh-oh. The EU just charged Google with giving preferential treatment to its own products and services in Search results and not giving app developers freedom to guide users to alternative platforms. Not nice Google, not nice…
