>>10147516The manager one.
You get a biz/economics oriented person with a very loose idea of the field (physics/engie/chem/med etc...) that is going to be put over you, is going to tell you what to do and will have the idea that he is smarter and is better in every aspect than those below him.
The only way to counter them is to be very specific and meticulous to cover your ground, rely on scientific facts and have related topics ready to cite from. They are bound to make mistakes and ready to put the blame on you.
If you manage to put him in a corner with facts and proofs they can't do shit and leave or bounce upwards.
