Most companies still believe they can understand customers by asking them questions. They trust interviews, surveys, and focus groups. People describe their habits with confidence. They make bold claims about what they will do in the future. Kristen Berman, a behavioral scientist featured at TEDxBerlin, shows why those answers cannot be trusted. Human behavior regularly contradicts human speech. This is where behavioral design becomes essential.

Her research highlights a hard truth. People do not choose based on deep analysis. They choose the easiest available path. Retirement savings demonstrate the point. Auto enrollment leads to participation above 90 percent. Opt-in programs rarely reach half that number. Employees explain their decision with idealistic reasoning. The real driver is simpler. The default choice did the work for them.

Similar gaps appear in health and lifestyle. People claim they wash their hands often. Real observation proves they exaggerate. Patients insist they will take life-saving medication. Many abandon it within months. Workers say they would grab the apple in the cafeteria. They reach for the fries. Individuals picture a perfect future version of themselves. The present version does not cooperate.

Berman promotes behavioral design as the fix. That idea matters beyond product design. It also explains why more SMBs are rethinking how they buy marketing support in the first place. When pricing is layered, scope is unclear, and the path to getting started feels harder than it should, hidden inefficiencies start before the work even begins. One of the more visible CEO trends is the push toward simpler systems that reduce friction and make decisions easier to act on.

That is part of why a challenger marketing model built on predictable, ongoing support can be more effective than fragmented engagements. It aligns with actual buyer behavior. People move faster when the choice is clearer, the next step is easier, and the value is easier to understand without extra effort. Teams map every step required to complete a behavior. They identify the psychological forces that disrupt progress. Then they run real experiments in the real environment. This is the practical value of behavioral design. Her work on student financial aid proves the impact. Students blamed lack of information. The actual barrier was cognitive overload. A small change to the enrollment process tripled applications among those who previously never applied.

Even when leaders understand buyer behavior more clearly, many still face an execution gap between insight and action. Marketing may attract attention, but sales and delivery teams are often left working through unclear messaging, uneven handoffs, or offers that create more friction than confidence. That slows decision-making and makes conversion harder than it should be. Proxxy helps close the sales and marketing gap by aligning strategy, messaging, and execution around how buyers actually behave, while also helping leaders reduce hidden inefficiencies and build simpler support models that are easier to understand, easier to buy, and easier to sustain over time.

Companies that keep trusting what customers say will continue building products people ignore. Results improve when leaders study what customers do and redesign the environment around real behavior. That is how organizations create outcomes that actually stick through behavioral design.
