They know every feature. They passed the certification with flying colors. They can answer any technical question about your product. Yet when they get in front of a prospect, they freeze, ramble, or dump information until the buyer's eyes glaze over. The problem isn't that they don't know enough, it's that they know too much. Neuroscience reveals a startling truth: extensive product knowledge actually sabotages sales performance by overloading working memory and triggering the information-dumping reflex that kills deals.
