Negative force multipliers are easily remedied: just make sure you have an even number of them.
We had a guy who would argue about everything that knew the CTO so we had to tolerate him.
Then we hired a second one and they just argued with each other all the time and the rest of the team could finally make progress.
It was awesome.
