two little logic tests

[Oedipus]

15 and 13.

Woohoo, first time I've applied any uni learnings to anything. Life's good.

15/15. Perhaps I got lucky

 

[nearfantastica]

80% in both. :\

I got zero on the first test and zero on the 2nd. You may wonder why I got such an abnormally below average score.

Spoiler

I failed to click on the links and thus failed badly in answering the questions. Don't know if that is logical or not as there must be some explanation.

15/15 (100%) on test 1.

15/15 (100%) on test 2.

Double 'o 14

I got 15 right on the first one, and I only answered 13 (and got 13 right) on the second one because I found two questions confusing -- Question #6 and Question #12. I thought the other questions were straightforward and didn't really have an issue with them or spend much time on them... there were a few that were supposed to be tricky and provided wrong conclusions but accurate logic.

Spoiler

#6. The question about Mary that appeared in test 1 -- she "admits" the crime, here, but she could be lying (although the test taker said not to bring prior experience /baggage into the test). My thought was that we were not told whether or not Mary was trustworthy, so the statement is ambiguous, which leads to a strong case for inferred guilt but not deduced guilt. And I guess that's the answer they wanted.

#12. I didn't even understand the statement. Was it supposed to be nonsense? What's a "beak"? And again, we're told not to bring prior experience into the test, so how can we just what "up" is supposed to mean, unless we bring in our baggage of what we know "what goes up must come down" already means.

I studied logic at university recently so I kind of know all the tricks. The second murder one got me though, started thinking too hard about reality versus the actual logical content. They use the term 'beyond reasonable doubt' for a reason.

Yup. You can make strong cases for something without being able to definitively prove it -- short of having actual visual evidence of them having committed a crime. And even nowadays, visual media can be changed. It's interesting how human recollection of detail can be amazingly inaccurate (because our brain fills in the gaps / tries to reconcile inconsistencies), and how not even photographs are reliable.

IOW, "beyond reasonable doubt" is all we've got.

Induction Fallacy. Science perpetuates this fallacy of logic all the time though it doesn't care too much. The thing to remember about inductive arguments is that they are always invalid.

Yeah, I guess you're right. Fudge.

Which bites, when the brain happens to be geared for inductivity.

And looking at your other posts: Yeah, for any I didn't see right away, I just broke it down into terms of If A, then B, then C, etc., and it all was more clear at that stage. That Set Theory class as far back as high school where I first learned logical symbolism still comes in handy.

I got them all right.

I actually really enjoyed this, some of the questions got me laughing pretty hard.

Got 12/13, 80% & 87%

Not too sure what I was expecting but they were fun/engrossing and some put a slight smile on my face, and so a few notes on that.. I don't remember which ones I got wrong the part II, but for both tests I knew the answer sort of depended on how one interprets things.. So some may have been worded less than ideal, and it was recognizable that interpreting it a certain way as opposed to another (the other?) way would yield an incorrect answer, so some questions were sort of gambles in certain regards, plus I suppose that is partially related to one of the main ideas of "logic" & reasoning.
Also, I believe I was partially stoned at the time of taking the quizzes, so I'm not sure how much that would affect a performance. I was sort of interested in seeing how that would go, however, unless my memory is wiped or an equivalent set of parameters can be set up I'm not sure how accurate any sober results would turn out in comparison to the partially stoned ones. For whatever reason I'd bet they'd be somewhat similar.

Some of the queries -- including the ones that were logically correct but resulted in an absurd answer -- were pretty amusing.
