What Is Social Proof?
Social proof is a behavioral science principle where people often look to others when deciding how to behave.
Whether it’s picking a restaurant based on reviews or choosing a product endorsed by friends, social proof taps into our instinct to follow social cues, especially in uncertain situations.
In a world of overwhelming choices, consumers use the actions and opinions of others as mental shortcuts to make decisions. This can include testimonials, social media metrics, influencer endorsements, or simply seeing others engage with a brand.
Why Should You Care?
Because consumer decisions rarely happen in a vacuum. But when consumers report on why and how they make their decisions, they may not even be aware of how much the people around them impact their own behavior.
Research has shown that strong social proof—such as regularly updated customer reviews or visible user engagement—can increase revenue by 62% per customer. 92% of consumers hesitate to buy a product when no customer reviews are available, and 88% of consumers trust user reviews as much as personal recommendations.
When market researchers account for social proof by designing studies that isolate peer influence or analyzing discrepancies between claimed behavior and observed trends, they uncover the social dynamics that subtly guide decision-making. This leads to more accurate segmentation, better message testing, and stronger predictive models that reflect real-world behavior, not just self-reported preferences.
How MDRG Applies Social Proof to Research Strategy
At MDRG, we integrate behavioral science principles like social proof into our WHOLE MIND™ Approach, accounting for System 1 (emotional, intuitive) and System 2 (rational, deliberate) thinking.
By understanding how and why people rely on social cues and including lines of questioning that help reveal underlying, nonconscious motivations, we help brands uncover the deeper insights behind decision-making.
In a recent study with a major beverage brand, MDRG examined how perceptions of brand popularity influenced purchasing and consumption habits. By digging deeper into their responses in a qualitative study, we saw that social proof was the main factor in the differences between what people said they did and what they actually did.
Armed with this knowledge, we were able to make recommendations about how to combat specific perceptions of their product that may be acting as a barrier to purchase.
