Do traits truly matter for some jobs? Is there some forced parity stuff going on? Do I need to get specifically negative traits to stop pops doing that exact job?
As a Driven Assimilator, Mechanist or Syncretic Evolution you can get early on a second species to utilize more different trait points. For the love of god why are they changing their job?
Just do some completly opposed pops and see how that fares on game starts. Sadly after a month jobs readjust and you need to do that stuff again.

Okay, some slighty rounding numbers to get that one month going. These Job Allocations were with some mods.

Just look at that without mods. I couldn't even change the behavior until year 2201. Was finally capable to swap the science jobs (i do hope they keep their jobs). The Droids are Repugnant and still focus on producing Amenities. They don't want to swap jobs.

That's just gamebreaking. Why do I need other species for specialization? Clearly not working.
