65% of people who have taken this simple logic test have failed. Can you be among the 35%? "What Does Mary Do?" http://bit.ly/ZH99xh 

@PhilosophyExp Hmm. That test is flawed, surely? Logically makes sense, but the existence of option 4 implies option 2 is in contrast. 1/3

@owenphelps @PhilosophyExp [>] absent in the 'language' of the Question page. Just makes it a sloppily-put-together puzzle or test. *shrugs*

@LyonJE @owenphelps Oh do be quiet, the pair of you. This is a standard test to show we can be misled by linguistic conventions.

@PhilosophyExp @owenphelps That's not being 'misled', that's linguistic interpretation. And 65% of English speakers read it that way.

@LyonJE @PhilosophyExp Indeed! That's been my problem with this standard test for some time. It *thinks* it's a logic problem, but it's not.

@owenphelps @LyonJE The analysis says precisely that people get it wrong because of linguistic conventions. This isn't a suprise.

@PhilosophyExp @owenphelps In short, the premise is flawed. It's not testing logic, it's testing how people interpret non-formal ambiguity.
