What are some "best-guess" answers for your academic discipline (or job)?

When I was a computer science major, my professor once said, half-jokingly, 'if you're ever stumped on a question on a CS exam, just guess 2^n-1. You'll stand a good chance of being right.' I mentioned that to my wife one day, and she said, 'my chemistry teacher once said that the best default answer on a chem test is hydrogen bonding.'

What are other best-guess / effective-BS answers for your academic discipline (or profession)? Bonus points if you can (briefly) explain why the default answer is so common.

(I'm not training to become a professional bullshitter; I just think this is a fun question! And an indirect way to learn about other fields.)

My mom and I are big trivia nerds.

Back when she was doing academic quiz bowl-type stuff when she was in high school, apparently flax was a really popular topic. If there was ever a question about a plant, fiber, or fabric, the answer was always flax.

When I was in high school, the answer was always lichen. At one meet, the proctor started with "this symbi--" and I buzzed in and said lichen. The answer was lichen.

There were a couple more stock answers for various categories (opera? always Pagliacci), but I can't remember most of them. But knowing "lichen" was clutch.

Hmm, I wonder about 2^n-1. If you asked me to give an answer to a random computer science question without knowing what it was, I would guess "order n log n."

This is not an academic discipline, but the two most likely answers to a question beginning "What is this classical piece of music" are 1) the first movement of Bach's Cello Suite No. 1 in G and 2) Carmina Burana. Although that Requiem for a Dream piece is gaining fast.

In linguistic anthropology (at least the school of ling anth that I'm in): dialogism. Or indexicality.

(Granted, you aren't administered a lot of tests when you study linguistic anthropology, so there isn't really a context in which a "default answer" could exist. But when I was reading for my quals, it seemed like 80% of the time, one of the main points of an article or book was that the linguistic phenomenon in question was dialogic, though the term "dialogic" wasn't always used.)

If it's a calculus problem, take the derivative of a function and set it equal to 0. Failing that, integrate that function over the given interval.

If an inequality is involved, see what the Cauchy-Schwarz inequality gives you.

If it's a question on an analysis qualifying exam where I went to graduate school, you'd probably employ Littlewood's three principles.

Oh, and reading the second part of your question:

1. Taking the derivative of a function and setting it equal to 0 will allow you to find the so-called "critical points". These are the points where the derivative either is 0 or does not exist; since the derivative measures how the function is changing and calculus is all about dynamic relationships between things, if there's a question on a calculus test you don't know how to do, showing that you know something about dynamic relationships will get you "partial credit".

2. The Cauchy-Schwarz inequality is just a beautiful inequality in mathematics which appears in so many different areas that it probably has something to do with the inequality problem you're working on (not really, but did you check?).

3. My graduate school had a really heavy-on-the-measure theory based analysis curriculum (reminiscent of the Bourbaki style of abstraction, sort of). Littlewood's 3 principles sort of took all that rigor and expressed very succinctly and beautifully (at least to me) what the hell was going on with all of this "almost everywhere" and "almost uniformly" and all this such garbage. Once I understood the principles, you realize that "basically everything will behave nicely, you just need to massage it a bit".

I'm a logician, and I'm often teaching an undergraduate math/logic course. The answer to how to prove something you don't know how to prove is pretty much always: "Try proof by contradiction."

This is only half a joke. If you're proving something in propositional logic (natural deduction, to be specific), if you don't need proof by contradiction, there's always a fairly obvious, direct proof that can be gotten to just by following the structure of all the formulas involved. So all the tricky problems require proof by contradiction.

On a related note, when I did college bowl trivia, my favorite events were the "trash" tournaments, which featured primarily pop-culture content, but which also often featured silly or bizarre variants on the standard trivia question format. So one standard college bowl bonus question was the 30-20-10 bonus, where your team is given a sequence of clues to guess an answer, starting with a difficult clue for 30 points, moving to an easier clue for 20, and then to the easiest clue for 10 points. There's no penalty for guessing wrong, so you always would make some guess (often "Smith", if you have absolutely nothing to go on). In the trash tournaments, you would sometimes get a 40-30-20-10-5-1 bonus. The 5-point clue was usually very easy, and the 1-point clue would be utterly ridiculous like "The George Washington Bridge was named after him." Normally bonuses max out at 30 points, so the 40-point "clue" was usually impossible (e.g. "For 40 points, name this philosopher."), and just a chance to make a joke guess. I was not very good at trivia of any form, but I still pride myself that I once successfully guessed at a 40-point clue "Name this sport."

The correct answer, of course, was "jai alai".

Postmodernism.

Extra credit should be awarded for actually understanding what the term postmodernism in art refers to and its relation to the tenets of modernism, but it's the main descriptive term anyone who wants to look like they know anything about contemporary art throws around. It's an excellent word to use in order to appear knowledgeable about art because there's the whole meta snake eating its own tail thingie going on whereby the prevalent misunderstandings/misuses of the word by its speakers is an instructive example of a "no singular point of view, no one true interpretation" theoretical stance.

Lots of chances for both the speaker and the listener to feel smart while not really having to think very deeply or consider anything concrete or specific in regards to any given work of art, other than acknowledging we now live in a time of postmodernity and therefore all contemporary work is postmodern, followed by either sage head nods or regretful head shakes.

For criminology/criminal justice, I'd say: relative economic deprivation.

Most of the variability in both offending and (to a lesser extent) victimisation at some level is related to who is poorer than whom. This is true for both sociological (the relative positions of groups within a society) and psychological (correlates of individual differences in criminogenic traits) explanations of offending.

It's not always going to be the most correct answer, of course, and it largely means you have to ignore the more interesting question of whether it's a cause or a result, but I think it fits the scope of the OPs question.

The best default answer for a math test is zero. I actually once was a TA for a professor who routinely wrote exams where three or four out of the five problems would have "zero" as the answer, although this is unusual.

(For probability problems in particular, the best default answer is 1/2. If the probability of something were zero or one, that would be obvious, so split the difference.)

I brainstormed a few more with my girlfriend (a high school math teacher) last night.

High School Trigonometry:

√(2)/2

or less flippantly: "use the unit circle"


High School Algebra:
"get it equal to zero and factor"


High School Geometry:

SAS (as in the theorem that states that if two triangles have the same length on two adjacent sides and the angle between them, then they are congruent)

Set Theory:

"the empty set"


Combinatorics:

"the Catalan numbers"

If you thought the Fibonacci numbers were ubiquitous, you ain't seen nothin' yet.


Recursion/Computability Theory:

Diagonalization

This is the technique where you take a definition and you apply it to itself, and it crops up everywhere in the subject.

Perhaps most famously, it's at the core of the proof that there's no algorithm that can solve the Halting Problem. (The Halting Problem is the problem of taking a given program and deciding whether or not it will eventually finish executing (as opposed to getting stuck in an infinite loop somewhere).) The proof is actually pretty straightforward, once you get use to the diagonalization:
If you had an algorithm that could tell you whether a given program would terminate on a particular input, then you could write a program (call it P) that takes a program x as input and first decides whether or not x would terminate when run on the input x (would it terminate if it was applied to itself?). If x run on x would terminate, then P goes off into a infinite loop. If x run on x would not terminate, then P outputs 1. Then you ask: what happens if you run P on P? Dun-dun-DUN!

In the original Taboo game, one of the topics you had to get your teammate to guess was "rigor mortis". Now, my siblings and I had no idea what this meant.

In psych research, it seems like the answers are always "random assignment" or "add more participants".

Erwen you should really be teaching them intuitionistic propositional calculus, then you really wouldn't ever need to deal with any of this nonsense. Or, failing that, if you really insist on believing in ridiculous things like excluded middle, at least formalize your proofs in a sequent calculus style where it's more natural.

Every so often he posts more on his web page; currently the addendum is at a couple hundred. Not surprisingly most of them are fairly simple transformations of other ones, but still these are non-trivial enough that they've appeared in the published literature.
