Every boardroom and CX team worth their salt has implemented a Voice of the Customer (VoC) programme. We’ve been told these tools are essential — that measuring NPS, collecting customer feedback, and diving deep into survey insights is the key to understanding our customers.

But is it? What if we are clinging to this data like a drunk uses a lamppost.

A very wise man — David Ogilvy — once said:

“People don’t think how they feel, they don’t say what they think and they don’t do what they say.”

And decades later, behavioural science has proven him right.

We now know that most customer behaviour is driven not by conscious, considered thought, but by unconscious impulses, emotions, and biases. Yet, we continue to spend billions on asking customers to articulate their experience — expecting them to self-report accurately on complex, fast-moving, emotional journeys.

Let’s call it what it is: a false sense of certainty.

Are We Measuring the Wrong Things?

VoC programmes are fundamentally built on the assumption that people know why they do what they do — and are willing (and able) to tell us.

But customers are:

• Often unaware of the true drivers of their behaviour
• Biased by recency, mood, social pressure, and how questions are framed
• Inconsistent between what they say and what they do

So why do we keep asking?

Time to Elevate Behaviour Over Voice

We believe it’s time to de-prioritise the voice — and elevate the behaviour.

Instead of obsessing over what customers say, let’s focus on:

• What customers actually do
• What unconscious cues shape their decisions
• How their environment influences their actions

This means investing in:

• Biometric tools to measure real-time, in-the-moment reactions
• Behavioural science to interpret emotional and unconscious drivers
• Designing experiences that influence and optimise desired behaviours, not just reflect opinions

Rethink the Spend

Here’s a radical question:
What if we stopped our VoC programme entirely — and invested that money in understanding and changing customer behaviour instead?

We’re not suggesting customer feedback has no place. But insight without behavioural understanding leads to misplaced priorities, flawed decisions, and wasted CX investments.

Instead, define the behaviours you want to see, understand what drives or blocks them, and design the system around behaviour change — not just feedback loops.

At CX Lab, we believe the future of CX is behavioural.

It’s not about giving customers more surveys.
It’s about giving your organisation more certainty — by seeing what people actually do.

Have we been hoodwinked by VoC? Maybe. But it’s not too late to break free.
