I think it depends on why they are asking. If they're asking because they have a specific limitation that will impede them (ie: they're blind/close to blind, have no depth perception, a prosthetic limb, etc.), then that makes plenty of sense for them to do the research rather than wasting time. If they have a list of potential schools, and want feedback while they're waiting to attend them anyway, also makes total sense.
The issue is when they see so many options, and just get stuck trying to decide. They'll see pros and cons of each, since that's how pretty much everything works, and ultimately if they do go they'll spend the time worried they chose the wrong one. Either paralysis or regret keeps them from training, when they would have been fine pre-internet or with only 1-2 options nearby.
There's a good, semi-tangential ted talk about the paradox of choice for anyone interested in a new perspective on this.
