Understanding the Semantic Differential Scale: A Comprehensive Guide

If you want to improve the quality of your company’s products or services (and who doesn’t?), it’s difficult to exaggerate how important it is to collect customer feedback.

Good customer feedback helps you improve your offerings, enhance team performance, grow brand loyalty and garner insights to make better business decisions in the future.

Customer satisfaction surveys are a great way to do this. The problem is the kind of information you get from basic surveys is limited—you need to take the time to think about what customer responses really mean and choose the right question types to maximize your data.

There's no better strategy for doing this than the semantic differential scale. In this post, we'll demystify the process so you can use the semantic differential technique like a pro and start reaping the rewards for your business.

What is a semantic differential scale?

When you Google the semantic differential scale, you’ll mostly find articles that read as if the writer ate a thesaurus for breakfast. If you collected all the five-dollar words you could fund an all-expenses-paid trip to Hawaii.

Why's this? Because the semantic differential scale has its origins in academia. And as the poet and author Charles Bukowski said, “an intellectual is someone who says a simple thing in a hard way.” So let’s try to cut to the chase.

The semantic differential scale is a survey rating tool that measures a person’s attitude towards something. It does so by asking respondents to make a judgement on a point-scale between two bipolar adjectives." For example, you could measure someone’s attitude towards their workplace culture with the scale below:

Why do we use semantic differential scales?

In the business world, this scale is used to ask people to rate an experience, product, idea or even a brand. It’s one of the most reliable ways to discover a person’s attitude towards, well, just about any topic you can think of.

The scale was developed in 1957 by Charles E. Osgood, a social psychologist who studied the field of psycholinguistics, a branch of cognitive science dealing with the mental aspects of speech and language.

In his research, Osgood discovered that across all cultures there are certain words and phrases that have negative or positive connotations. A connotation is an idea or feeling that a word invokes for a person outside of its literal meaning.

So while the word 'lion' refers to a large brownish-orange cat that lives in prides and is found in the African Savannah, its connotative meaning is bravery. In the same way, words like 'strong' and 'good' have positive connotations, while words like 'bad' and 'weak' have negative connotations.

While studying these connotations Osgood found there are three dimensions of 'affective meaning' that are universal across all cultures, regardless of language: evaluation (good-bad), potency (high-low) and activity (fast-slow).

Osgood realised that by using these antonyms (words with opposite meanings), you can understand a person’s emotional attitude towards just about anything. Voila, the semantic differential scale was born.

So how does it work? Well, you create questions with rating scales and ask respondents to give a judgement between two bipolar adjectives. Respondents then choose the point on the scale that best reflects their opinion.

The academic explanation for what the scale does is that it measures the connotative meanings of emotional attitudes toward specific objects so that it can be recorded. But that's a mouthful.

To put it in plain English, it helps you understand how people feel about a certain thing. This is great for two reasons:

  1. It lets you understand the value the respondent places on the topic and;
  2. It gives respondents an opportunity to show you how your product or service did or didn’t live up to their expectations

Now, what started as a technique for social ethnography (the study of people and cultures) has been adapted to many fields, from the social sciences and therapy to consumer research and video game development.

This technique has become useful for a variety of subjects for businesses. You can use semantic differential scale questions to ask respondents to rate products, services, user experiences, or your brand as a whole.

Hopefully we’ve managed to simplify these surveys for you, now let’s compare it to another survey type that you’ll have used before: the Likert scale.

What's the difference between Likert scales and semantic differential?

The chances are you've come across a Likert scale question when filling out a survey or questionnaire. Like semantic differential scale questions, it's a popular way to measure attitudes. It does so by asking respondents to express how much they agree or disagree with a predefined statement.

A question that uses the Likert scale looks like this:

A Likert scale question

Semantic differential scales and Likert scales are kind of like moths and butterflies. At first, they seem similar, but once you take a good look you realise they’re nothing alike.

Let’s deal with the similarities first. Both scales ask respondents to report on a certain element of their experience and feature a list of options presented on a rating scale. Both also share the goal of better understanding what customers like or don’t like about a product, idea, service or brand.

But there are two key differences:

  • How the survey questions are asked
  • What kind of information the researcher hopes to obtain from the responses.

Likert Scale vs a Semantic Differential: Differences

The main difference comes down to wording and perspective. Semantic differential questions are open-ended, where Likert scale questions aren't. Let's compare each scale to make the contrasts easier to spot.

1. The framing of the question

A Likert question gives you a concrete statement that you have to agree or disagree with.

In contrast, a semantic differential scale offers a more open-ended question that it’s up to you to complete based on your feelings.

With a semantic differential question, you can choose between the two contrasting words with options in between. There’s no need to ‘agree’ or ‘disagree’. If you don’t think the blog post is great, you can just skew your answer slightly to the left.

You’ll notice the Likert scale question starts with the assumption that ‘this blog post is good’. Intentionally or not, this uses the power of suggestion to plant the idea in your head that the blog post is, well, good.

Now imagine, instead, it says ‘this blog post is bad’. The question suddenly takes on an entirely different tone that can bias responses. The semantic differential scale provides bipolar adjectives that let you define the degree to which the blog post was great or terrible.

2. The semantic scale allows more autonomy

The second big difference: semantic differential scales allow users more autonomy to express unique opinions in their responses compared to Likert scale questions.

Where Likert scale questions are worded in a way that’s more restrictive and declarative, the bipolar adjectives of the semantic scale leave room for respondents to interpret questions in their own way and express their thoughts with more accuracy.

Take a look at this image of the New York skyline.

An image of a New York skyline

Take your time to inspect the ombre sunset and the soaring skyscrapers of the Big Apple. When you’re ready, answer this Likert scale question in your head:

Notice how this Likert question defines the photograph as beautiful? Rather than asking your opinion on whether you find the photo of New York beautiful or not, it asks you to agree or disagree with the statement that it is beautiful.

Now take a look at how this changes with the semantic differential scale.

Notice how it doesn’t add an outside opinion? It’s up to the respondent, to decide how you want to define the image within the bipolar scales. The choice is in your hands.

Semantic differential scale surveys help you get a more accurate idea of customers’ attitudes by trusting them to define their own unique values rather than holding their hands. This lets people describe their own attitudes, opinions and feelings and leads to more specific feedback.

Using this technique not only simplifies the measurement of attitudes, but it also allows you to collect data that's more honest and reliable (which means it’s more useful to your business).

Semantic differential scale: best practices

Semantic differential scale surveys are best suited for when you need to gain insight into your attitudes, needs or opinions, or to measure satisfaction.

But before you do any of that, you’ve got to create the survey. There are a few key rules to follow:

1. Stick to the three dimensions

It’s best to make sure your rating scales stick to one of the three dimensions:

  1. Evaluation
  2. Potency
  3. Activity

Charles Osgood spent years researching these things so you don’t have to—there’s no need to try and reinvent the wheel.

This ties in with the type of questions you ask. Semantic differential scale surveys need to be conducted with open-ended questions. These encourage more than a simple yes/no response and allow respondents to communicate their thoughts about the subject at hand.

2. Settle on the right bipolar adjectives

The hardest (and most important) part of creating your semantic differential survey is figuring out the right bipolar adjectives to use.

Finding the right antonyms is the key ingredient to success, so make sure you spend some time thinking about which words suit each question.
