It would be interesting to find out how the bias-reducing effect is related to the mastery of the language. I guess that fully mastering the language is not necessary for this effect, and even could reduce it.
My model is that by speaking in a foreign language we have to pay more attention to our thoughts, and we have to make more things explicit. Thus it is more difficult for some biases to be unnoticed. Fully mastering the language would make the biases easier too.
(I am not sure about the cost-efficiency, because I don’t know how strong is the effect, and how strong are effects of alternative methods. If the effect is strong, perhaps spending two weeks learning Esperanto using Anki would be worth doing. But I guess the effect is not very strong.)
