A system should be easy to use.
My question: will a drunk user be more error prone and likely to expose the flaws in a website more easily?
There's an article out there that I can't find now that advocates doing guerrilla testing in bars because it's a social environment where people are willing to help out for the price of a beer. I like the idea, though I've never done it.
You probably don't want to test with the heavily inebriated, but a beer and a half loosens people up and might make them into better subjects. Testing in a bar also provides some elements of real life, with interruptions and noises, that are missing in the lab.
In my opinion thats compeltely wrong because drunk people arent less experienced,they are less logical in their actions and more prone to do STUPID mistakes,and not real mistakes.
If a drunk person trips over a ledge, is that ledge dangerous or the drunk person too drunk?
If anything i think older people are much more likely candidates to find out such flaws due to their possible inexperience in technology, if my grandma understands that pressing this shows me more information, i can be pretty assured my target audience will probably feel the same way about it even if they have never used any other websites beforehand.
edit: this does not mean we should put elderly people to try out our gaming forums,since they are not the target audience. im saying that in a specific group of people: for example "gamers" the best testing candidates are the ones with the least experience in the service,because they are less likely to get used to the common UX FLAWS that plagued them beforehand. never test your service with irrelevant people because you are adding another layer of falsehood to your results (ex: children not understanding certain industry standards on a finance website for buisness managers is NOT a UX flaw)
Only if you expect your users to be drunk as well. This is a marketing gimmick being dressed up as UX. Avoid.
Only if you value the feedback of an inebriated "full stack developer" who happens to be a "UX expert." Chances are good not many site visitors will fit that demographic.
Completely depends on the type of Application.
If your application is bound to cater to users who might be drunk, let's say for example - a Texting app that imitates your original texting app so that User does not send drunk texts to others, the app just stores the texts so that the user only thinks he sent them but in reality, it won't.
The idea is interesting! But, not anything more than a gimmick. Could work on Web sites for Bars, Pubs, etc just for the lulz.
