The short answer
Authority-driven professionals lose to generalists because expertise makes you precise and precision makes you hard to summarize. The generalist says one simple thing that is easy to repeat. The specialist says five accurate things that are impossible to remember. The buyer picks the one they can explain to their business partner.
The expertise trap
The more you know, the more exceptions you see. So your answers grow qualifiers. It depends. In some cases. Generally, though not always. Every one of those qualifiers is honest, and every one of them costs you legibility.
Meanwhile the generalist, who knows less, says something clean and slightly overconfident. It is less true. It is far more repeatable. Repeatable wins, because the buying decision is usually made when you are not in the room.
Positioning is not dumbing down
The instinct at this point is to resist, and the resistance is correct. Flattening real expertise into a slogan produces the same interchangeable noise everyone else makes.
The move is not simplification, it is selection. You are not reducing what you know. You are choosing which single true thing goes first, so the rest has somewhere to attach. Depth is the reason to hire you. It is a terrible reason to be remembered, because nobody remembers depth. They remember shape.
Where the deal is actually lost
Rarely in the pitch. Almost always in the retelling.
Someone who liked you tries to describe you to someone else. If your positioning is a list, the retelling collapses into a category label, and a category label puts you back in the comparison set alongside three cheaper options. You never see this happen, which is why it goes uncorrected for years.
The fix
Give people one sentence to carry. Not your whole capability. One sentence that is specific enough to be interesting and short enough to survive being repeated by someone who is not you.
That sentence should contain the thing you have been leaving out because it felt irrelevant: the previous career, the unusual combination, the lived experience that has nothing to do with your credentials and everything to do with why you see the problem differently.
The material that makes you distinctive is almost never on your resume. It is the part of your history you assumed was off topic.
