Humans are built to focus on some objectives and not others at any given time.

Humans naturally prioritize objectives differently. Drives have exclusionary impacts on each other. In both real time and lifetime frames.

Reinforcing experiences further differentiate objective prioritization.

This leads people's behavior to be driven by entirely different net objective directions.

This diversity would be inevitable due to genetic diversity. But it is also a survival advantage.

Lots of studies show that populations maintain stable diversity of genes for entirely different life strategies, because operating differently from the majority is an advantage.

We don't actually have a "status drive".

We have drives that tend to generate status seeking behavior but can be subsumed by many different status-like pursuits, such as self-status of solving problems or completing single-person video games, being good at a hobby nobody else cares about, pleasing certain people even to the point of harming any recognizable definition of social status, acting to please (raise status with) internally generated or deceased personalities, a need to be contrarian or difficult to the point of low-social status but high internal status, etc.

Your assumption that same basic nervous system -> same net drives/behaviors, fails in much simpler species.

So no, mathematicians are no more motivation clones than they are genetic clones.

And mathematics is not a field that is attractive to people who give social status high priority, because it impedes social status.
