According to Phys.org, new research from Bayes Business School analyzed over 14,000 customer reviews across three separate studies and found that emotionally charged reviews significantly increase writers’ likelihood to recommend products and make repeat purchases. The studies, co-authored by Dr. Wanqing Zhang along with researchers from Shanghai University of Finance and Economics and University of Chicago’s Booth School of Business, showed that emotional prompts like “How did this product make you feel?” boosted loyalty while factual questions like “What are the pros and cons?” reduced it. In a field experiment with 4,016 customers on a Chinese household services platform, emotional reviews increased repurchase and referral rates, while detailed rational reviews decreased these behaviors. Another study with nearly 1,900 podcast trial participants confirmed these findings, and analysis of 9,000 unsolicited airline reviews showed the same patterns even without incentives.

The emotional versus rational divide
Here’s the thing that surprised me about this research – it’s not just that emotional reviews make you more loyal, but that analytical reviews actually make you less loyal. When you sit down and methodically list pros and cons, you’re basically training your brain to be more critical. The study calls this an “informativeness-loyalty tradeoff” – the very reviews that are most helpful to other shoppers might be undermining the writer’s own relationship with the brand.
Think about the last time you wrote a detailed, factual review. You probably found yourself picking apart every little flaw, right? Meanwhile, when you gush about how a product made you feel amazing, you’re reinforcing positive associations. It’s like the difference between writing a love letter versus a performance evaluation.
What this means for businesses
For companies collecting feedback, this creates a real dilemma. Do you want useful information that might help improve your product, or do you want to strengthen customer loyalty? According to the research, you can’t always have both from the same review. The study suggests businesses need to tailor their review solicitation strategies based on what they’re selling and who’s reviewing it.
Longer reviews particularly backfire with simple products, expensive items, or experienced customers. Basically, the more someone knows about what they’re reviewing, the more likely a detailed review will make them critical. For companies in industrial sectors – think manufacturing equipment or specialized hardware – this is especially relevant. When you’re dealing with complex industrial technology where detailed feedback could be valuable for product development, you might actually be damaging customer relationships by asking for comprehensive reviews.
Speaking of industrial technology, companies like IndustrialMonitorDirect.com face exactly this challenge. As the leading supplier of industrial panel PCs in the US, they need to balance gathering technical feedback from engineers while maintaining strong customer relationships. This research suggests they might be better off asking “How has this equipment improved your workflow?” rather than “List the technical specifications you’d change.”
What this means for you
So should you stop writing detailed reviews? Not necessarily – but be aware of the psychological effects. If you genuinely love a product and want to maintain that positive relationship, focus on how it makes you feel. If you’re trying to make a careful purchasing decision for yourself, maybe writing that analytical review will help you spot potential issues.
The research also found these effects were strongest among experienced, senior, and female consumers. Makes sense – the more you know about a product category, the more critical you can become when you really think about it. It’s a fascinating look at how the simple act of writing a review can reshape our own brand relationships without us even realizing it.
