I'm an INFJ and I scored 15/15.

I'm an XXXX and I scored 14/15.

two little logic tests

Test #1
14 / 15 (93%)
The only one I got wrong from test #1 is question 15. Though I was unsure of question 14, but got it right.


Test #2
11 / 15 (73%)

Question 10 had confusing semantics.

You're not supposed to address admins by their role. (They'll ban you next.)

13/15, and I failed only because of indoctrination: I'm used to expecting "the truth, the whole truth, and nothing but the truth" and the validity of court rulings, so I flunked the questions about economics and murder. Curse you, propaganda!

Deduction test: 13/15. I got 2 (economics) and 14 (fat person -> thin person) wrong. I thought 2 really was a difficult question, and I'm convinced that number 14 was flawed.

Logic test: 14/15. I got the last one (H2O) wrong. My line of thinking: you can make the prediction, but that doesn't mean it will be correct.

It's a measure of only deductive logic. The problems you guys stated difficulty with are all entirely reasonable assertions to make so long as you are not taking a test on deductive logic.

isn't question number 3 paradoxical?

though i guess you can settle it as invalid anyway thanks to premise 2.

Yes, that's what makes it invalid, isn't it?

An argument is valid if and only if, given the premises are true, the conclusion must also be true.

Regardless of whether the statements are a paradox, it does not follow from

a) Both premises in this syllogism are untrue
b) Words constitute all the content of any premise.

that

c) The words in this syllogism are all false.

If there were a third premise that stated that all words in a premise are false if a premise is false, then we might have a valid argument.

The trick with paradoxes is to ignore them if at all possible, because they're really rather fucking tricky.

14/15, although I must say that some of those questions had very little to do with logic.

yes, that's what i came to realize with my edit:

"though i guess you can settle it as invalid anyway thanks to premise 2."

that's not to discredit your effort in wording it.

I think you'll find they have a lot to do with logic.

13.

I missed 11 and... 12. Um... fair enough, I suppose. I'm just glad I didn't get the paradox one wrong.

These logic tests are always interesting to me because one will do horribly if he doesn't realize the difference between 'valid' and 'true'. That's all that logic is, really, the abstract relation between statements which may or may not be true.

14/15, damn. Was reading 'if all bogs are nogs and all nogs are togs' for the neutrino one.

 

[rushgirl2112]

15/15, no guessing, but I had to think pretty carefully about some of them!
