Yes, but we’re not talking about long-term research here. It wouldn’t be hard at all to get a bunch of volunteers interested in learning a language, and randomly assign them to one of the various different treatments popular in the industry (MT, Pimsleur, Rosetta, traditional classroom instruction, whatever). It would take less than a year, probably.
(Various choices would be up to the experimenter, like whether they wanted to control time so all groups spent, like, an hour a day or whatever, or examine the time students chose to spend themselves as one of the dependent variables, or whatever. Obviously it would be best to do it both ways.)
Obvious, easy, and valuable. Just nobody with the resources has the incentive or the perspective to see that it should be done.
Anyway, I’d expect to see a pretty high failure rate even for the MT courses. Just a significantly lower failure rate than any of the other courses.
