From the journal Nature, there is recent research that suggests that ranked choice voting/instant runoff voting improves voters' perceptions of democracy.

A study found that participating in RCV elections can enhance voters' support for democratic principles, even when their preferred candidate does not win[1].

Additionally, RCV has been posited as a means to improve the electoral performance of third-party candidates, potentially breaking the two-party stranglehold that many Americans feel limits their choices[5].
