So far, I have noticed some questions that are not really related to the process of learning a language, but effect of it to the learners. Three examples:
- Does learning a second language happen in the same part of the brain as learning a first language? (well-received)
- Why does learning languages help with aversing dementia? (closed)
- Is there any evidence that vocabulary level is a good measure for predicting success? (closed)
Is this kind of question on-topic? For the first two questions, I don't see any different between them (in fact they are asked from one user, tagged with only one tag: neurology), yet received two different altitudes. The third question is mine, and I would argue that if we are fine with questions ask for neurology aspect of the learners, then we will be fine with questions ask for the economic aspect.
