What Consumers Say vs. What They Do: Closing the Behaviour Gap in Market Research

Consumers are not always perfect predictors of their own behaviour.

A shopper may say price is the most important factor, then choose a more expensive brand. Someone may report strong brand loyalty, then switch when they see a promotion. A consumer may intend to compare several options, but make a quick decision once they are standing in front of the shelf.

This difference between what people say and what they actually do is often referred to as the behaviour gap.

For market researchers, understanding that gap is important because stated opinions and real-world behaviour do not always tell the same story.

Both matter.

The strongest insights often come from understanding where they differ and why.

Why Stated Intentions and Actual Behaviour Can Differ

Surveys and interviews are valuable because they allow consumers to explain their opinions, preferences, and intentions directly.

But people do not make every decision in the same way they describe it later.

Memory can be incomplete.

People may simplify their decision-making when explaining it.

They may also overestimate how carefully they compare options or underestimate the influence of factors such as convenience, packaging, promotions, availability, habit, or impulse.

A consumer might say:

• “I always compare prices.”

• “I usually buy the same brand.”

• “I plan my purchases before going to the store.”

• “Advertising does not really influence me.”

Then their real-world behaviour may show something different.

That does not necessarily mean the consumer is being dishonest.

It often means that real decisions are more complex than people realize.

Context Changes Consumer Decisions

Consumer behaviour is shaped by the environment in which a decision happens.

Inside a store, for example, a shopper may be influenced by:

• Product placement

• Shelf position

• Promotional signage

• Package design

• Stock availability

• Price differences

• Competing products

• Time pressure

• Who they are shopping with

• Previous brand experience

Many of these influences happen quickly.

A consumer may not even consciously recognize all of them.

That is why asking someone about a purchase after the fact can produce a different picture from observing the decision while it happens.

The context surrounding the choice matters.

The Difference Between Memory and the Moment

Traditional research often asks consumers to recall an experience.

“What made you choose this product?”

“What caught your attention?”

“Which brands did you consider?”

These questions can generate useful insight, but they rely on memory.

The longer the gap between the experience and the research, the more details can disappear.

Consumers may remember the final decision but forget smaller moments that influenced it.

Research conducted closer to the point of experience can capture more of those details.

For example, a shopper recording a short video while examining a display can explain what they notice in real time.

An observer can see which products receive attention and which are ignored.

A contextual interview can explore why a decision changed at the last moment.

These approaches add another layer to what consumers report in a traditional survey.

Observation Helps Reveal What Consumers May Not Mention

Observation does not replace direct consumer feedback.

It complements it.

Watching how people interact with products, spaces, or services can reveal behaviours they may not think to mention.

In a retail environment, researchers may notice that consumers:

• Pick up several products but only compare two closely

• Look at promotional signage before checking price

• Ignore certain areas of a display

• Ask another shopper for advice

• Return a product to the shelf after reading the packaging

• Change their choice when their preferred product is unavailable

These moments can be difficult to capture through recall alone.

They can also help researchers ask better follow-up questions.

Instead of only asking, “Why did you choose this product?” researchers can explore the full decision process.

Video Adds Context to Consumer Feedback

Video-based research can be particularly useful when the research question depends on environment and behaviour.

A participant can show what they are seeing, explain what they are thinking, and capture the context around a decision.

That can provide information about:

• Store conditions

• Product displays

• Packaging

• Promotions

• Competing options

• Consumer reactions

• Decision-making sequence

The value comes from combining what the participant says with what is visible in the environment.

A statement such as “this display caught my attention” becomes more useful when researchers can see the display, its location, the competing products around it, and what happened next.

Combining Methods Creates a Fuller Picture

The behaviour gap is one reason market research often works best when multiple methods are used together.

Quantitative surveys can show how common a behaviour or preference is.

Qualitative interviews can explain motivations.

Observation can reveal actual behaviour.

Video can add context.

Each method answers a different part of the question.

For example, a survey may show that consumers rank price as an important purchase factor.

In-store research may reveal that packaging or product visibility has a stronger influence at the moment of choice.

Follow-up interviews can then help explain why.

Together, these methods provide a more complete understanding than any one approach on its own.

Why the Behaviour Gap Matters for Brands

Understanding the difference between stated intentions and actual behaviour can improve decisions across many areas of a business.

It can help brands:

• Improve product positioning

• Evaluate packaging

• Understand promotional effectiveness

• Refine retail displays

• Identify barriers to purchase

• Improve customer experiences

• Understand switching behaviour

• Test whether stated preferences translate into action

It can also prevent organizations from making decisions based only on what consumers say they intend to do.

Intentions are important.

But behaviour shows what happens when consumers are faced with real choices.

Better Research Connects the Two

The goal of market research should not be to decide whether stated feedback or observed behaviour is more important.

Both provide valuable information.

The opportunity is to understand how they connect.

What consumers say can explain attitudes, expectations, motivations, and perceptions.

What consumers do can reveal how those factors interact with real-world conditions.

When researchers bring the two together, they can move beyond simple answers and develop a deeper understanding of how decisions are actually made.
