Approval voting is used in scientific bodies, and it makes sense to use that there as they are professional colleagues. I'm not concerned about the specific tactics this (ranked choice) voting method encourages as much as I am the general direction. The two party political divide in the USA is maintained by the plurality voting method and neither party wants it to change. Ranked/preferential voting methods have better mathematical properties that should help to erode this divide. It's not perfect, but it is an improvement.
