A Win Can Hide a Weakness. A Loss Can Hide Sound Work.
Sales Results Can Mislead: Evaluate the Behavior Behind Every Deal
Why sales outcomes can give sellers the wrong signal about the behaviors that led to them.
In sales, people often use the result to judge the performance. A win is treated as proof that the seller did everything right. A loss can be treated as proof that something went wrong.
That reading can be false. I use the terms false positive and false negative to describe what happens when the result gives us the wrong signal about the behavior.
The false positive
A false positive happens when the seller’s behavior was weak, but the result was positive. The deal closes, so the seller and manager may assume the approach worked.
For example, a seller might skip discovery, make assumptions, talk over the buyer, or push a solution before understanding the need. The customer still buys because the problem is urgent, the timing is right, or the buyer had already decided. The sale counts as a win, but it does not prove the seller’s choices were sound.
If the only feedback is “Great job, you closed it,” the seller may repeat the same habits. That can work for a while. It can also lead to missed needs, poor fit, or a customer who later regrets the decision.
The false negative
A false negative happens when the seller’s behavior was sound, but the result was negative. The seller prepared, listened, asked useful questions, connected the recommendation to the buyer’s needs, and confirmed the next steps. Then the budget was frozen, the buyer’s priorities changed, or a key decision maker left.
The opportunity is lost, but the loss does not erase the quality of the work. If a manager judges only the final result, the seller may conclude that the right behaviors do not work. They might overcorrect, stop asking thoughtful questions, or become more forceful in the next conversation.
That is how a disappointing result can undermine confidence even when the seller did many things well. It is also how coaching can accidentally teach a rep to abandon a useful behavior.
Separate the behavior from the outcome
A false positive does not mean the seller is bad. A false negative does not mean the seller is blameless. These terms describe a mismatch between the behavior and the result. They are a prompt to investigate, not labels to put on a person.
After a win or a loss, ask what the seller did before deciding what the result means. Did they understand the buyer’s need? Did the recommendation fit? Were assumptions checked? Did the seller learn how the decision would be made? Was the next step clear? Did something change outside the seller’s control?
Those questions help you decide what to reinforce and what to practice. If a weak approach produced a win, recognize the result while being honest about the behavior. If sound work ended in a loss, identify any real improvement and preserve the parts that served the buyer.
A win is not proof that the behavior was sound. A loss is not proof that the behavior was poor. Before you decide what to repeat or change, ask whether you are looking at a false positive or a false negative.
