I think that there are a lot of issues with the way Duolingo motives people through unhealthy incentives, but research does show that it works. Though it will need to be used in conjunction with other methods of learning to be truly helpful. But then, why would you learn a language if you’re not going to actively use it?

No, research doesn't show that it works.

That research you link has been conducted by Xiangying Jiang and Bozena Pajak (first and last authors). If you want to contact them about how totally objective and unbiased they are, here are their emails:

This reminded me of that story by Feynman where he meets a painter that claims we can make orange paint with just red and white.
