📝 Context
Topic: Customer Experience
For: B2C. Can be tested for B2B
Research date: June 2016
Universities: Michigan State University, Indiana University, University of Maryland
You’re the managing director of a digital agency. You’ve grown exponentially this year and are super happy about your team’s performance. You feel confident, this has been the best year so far. Surely your long-term retainer clients are happy.
Except…
At the time of renewing their contracts, many have started churning, and it seems to be getting worse.
What happened? You really thought they were happy.
Science says, it’s very likely you overestimated your customer satisfaction.
P.S.: One proven way to have a closer relationship with your customers is for your organization to have a Chief Marketing Officer (CMO), and this has real consequences.
An analysis of 1604 public firms’ performance over 12 years found that those with CMOs performed ~15% better than firms without one.
📈 Recommendation
Use rigorous and various methods to understand your customer satisfaction and avoid being biased. For example:
If you’re an ecommerce, run surveys on your website, ideally at different stages of your customer journey
If you’re a service-based business, schedule regular client check-ins (e.g. informal chats during meetings)
Anonymous emailed questionnaires, monitoring reviews, and online sentiment analysis are all helpful methods
Make sure you always have both qualitative (e.g. open-ended questions) and quantitative data (e.g. NPS score) to ensure your analysis is objective. Pay special attention to the key drivers of satisfaction (e.g. product/service quality, assistance & communication).

🎓 Findings
Managers consistently overestimate how satisfied their customers are, underestimate their complaints, and misunderstand what drives that satisfaction.
As part of an analysis of 70,000 customer surveys from the American Customer Satisfaction Index and 1,068 manager responses from 97 large firms, researchers found that managers, compared to what customers actually said:
Overestimated customer satisfaction levels by an average of 4.1%
Overestimated how high customers’ expectations of their products were by 3.9%, and perceived value by 2.9%
Overestimated customers’ intentions to repurchase by 4.9%
Underestimated the number of customers who had raised complaints by 30%
They also found that managers didn’t understand what drives customer satisfaction and loyalty, they:
Underestimated the impact of quality on customer satisfaction by 31.6% and by 65.3% on how valuable customers saw the product
Underestimated how relevant customer satisfaction was on reducing complaints by 57.5%
🧠 Why it works
It is hard to trace how effective companies’ investment in measuring and improving customer satisfaction is. Our evaluation of metrics such as customer satisfaction is not objective, but is impacted by our biases.
When we are in a managerial position, we’re prone to the “rosy bias”. We are overly optimistic about our own performance and less harsh about negative consequences.
So even if we have the data available, we don’t interpret it correctly.
This makes us see customer satisfaction and attitudes more positively and underestimate negative sentiment.
📈 Custom science-based insights for your organization
One often overlooked area of increasing customer satisfaction is before your service even takes place. By making targeted tweaks, you can drastically improve how much people enjoy the actual experience.

✋ Limitations
The study showed that managers often misunderstand customer attitudes but did not check why.
The study focused on large companies, managers in smaller companies might have a clearer understanding of customer satisfaction thanks to a closer relationship.
Only US companies were analyzed, it’s likely but wasn’t tested that this same dynamic exists across different countries.
👀 Real-life example
Loom measures part of its customer satisfaction through emails. They send feedback emails to users and even segment them based on behavior (e.g. they ask why someone has stopped recording looms).

❌ Issue: Though they do ask for feedback, their surveys could be used to generate higher spending and reduce churn, but they’re not currently optimised to do so.
✅ Solution: Loom could slightly tweak their survey strategy to increase satisfaction and future customer spending. For example, they could:
Start their questionnaires with an open-ended question about what they liked the most, in a B2B experiment this increased spending by up to 32.9%.
For long-term clients who complete the survey, they could provide loyalty rewards to reduce churn.
Send emails from personal accounts, and sign them. This will make the experience feel more personal and increase satisfaction.

Remember: This is a scientific discovery. In the future it will probably be better understood and could even be proven wrong (that’s how science works). It may also not be generalizable to your situation. If it’s a risky change, always test it on a small scale before rolling it out widely.
