>I'd really like to see some double blinded studies comparing the success of echolocators in every day tasks against non-echolocators. I'm trying to think of how you could set up that study. There's a lot of factors you'd have to control for. You'd need to set up some kind of baseline to work off of. Which I feel like could be difficult with something like compensating for a disability. There's the length of time being blind to consider. Someone who's been blind longer likely has better abilities at finding their way around and finding things whatever methods they use. Then as another poster mentioned, there's controlling for echolators using different methods along with echolocation. Then there's sample size. To get an actual unbiased set of data work with you would need more than a handful of people. You'd need a fairly large group of disparate people in each category you're testing for to get any kind of statistically significant result. There's lots more to consider, these are just a few that came to mind off the to of my head. It would be a cool study to see done though.
