logic

Do you know those 'logic' puzzles where you have to choose which item 'logically follows' in some sequence, or which item 'doesn't belong' in some group? You can do them for fun ('brain training') or they can be administered to you in certain situations such as a job interview. People would normally be employed based on their relevant skills, but it seems some 'progressive' management types think that they should be 'logical' too. That's an idiotic practice and should stop, because:

A. My logic can be different from the author's logic, and that doesn't make it any less correct:


In hindsight, it should have been obvious to me that 25*25 is 625 and that 30*30 is 900, but at the time it was obvious to me that answer A is the only number not divisible by 3. Fuck you, gbrainy!

B. The question text can be ambiguous:


'Frontiers between different sheets' means that where there's a line a sheet ends and another one begins (like with countries, you know, they don't overlap). In that case it's impossible to build that shit because there are non-square 'countries' in it. So it's clear that (a) the question is wrong and (b) the sheets must overlap.
Now there's a question of what the author meant: whether that's how the figure is seen from above or the lines are just paper edges (like sea borders or something where there's no other country there) and maybe the paper is semi-transparent or something. Of course, if that's what's seen from above and the paper is perfectly opaque, you need 5 sheets, but if those are just (possibly hidden) paper edges somewhere you only need 4, which is less than 5. You might say that I'm stoopid and of course paper is not even conceptually transparent. But then why can you see the brain in the background through the sheets? Fuck you, gbrainy!

C. The questions can simply be annoyingly stupid:


Yeah thanks for lecturing me on how P is 5 letters away from K which is 5 letters away from F which is 5 letters away from A! I knew there must have been something like that, but I didn't even bother counting*, because the answer was obvious from comparing the three squares: A-B-C, F-G-H, K-L-M, P-?-R, gee, what letter could that be? There was a similar question with some clocks where they put forward a similarly contorted explanation, while the minute hands on each column were all pointing to the same number. Fuck you, gbrainy.

It's times like these when I dare say nethack is just fine.

this happened to me with a sequence of 4-digit numbers. i just added the digits and when only one sum turned out to be odd, i obviously picked that one. the answer was wrong though, and their method of elimination was far more complicated. some people just don't get the fact that most of us go with the easiest and more obvious solution
