This is a VERY common question every year. I'm sure there's a thread from last year, but I'm too lazy to search for it.
Issue #1. You CANNOT hurt yourself statistically by couples matching, as long as you put in all possible permutations. You might not want to put in all possible permutations, which is why couples matching is much more powerful than simply applying separately.
In the example above:
---
Now, if you couples match and do the rankings like this
Girl Boy
C A
B A
A A
C B
B B
A B
C C
B C
A C
-------
This is missing a VERY important option. It would be possible for one of the two to match to a program, and the other not to match anywhere. As this rank list is written, if both can't find a program, no one gets a program If you would want one person to get a spot, and the other to remain unmatched, you would add:
C UNMATCHED
B UNMATCHED
A UNMATCHED
UNMATCHED A
UNMATCHED B
UNMATCHED C
Now, the couples match and individual matches are completely identical. However, you get to control the order of preference for the match.
It's a better example when there are two cities involved. Let's say one half of the couple (Person 1) is applying to radiology, the other (Person 2) to IM. Let's say they apply to two programs each in NYC (Prog A and B) and San Fransisco (Prog C and D).
Ok, the couple now decides the following:
1. Our first choice is that we both match in the same program.
2. Our first choice is NYC
3. Our second choice is SF.
4. If we can't match in the same program, then we want to be in the same city.
5. If we can't be matched in the same city, then person 1 who is applying to Radiology should get any spot possible, and person 2 (IM) will go unmatched.
6. Barring that, Person 2 gets a spot, and person 1 goes unmatched.
Given these rules, the match list becomes (X = NO MATCH)
A A
B B
C C
D D
A B
B A
C D
D C
A X
B X
C X
D X
X A
X B
X C
X D
Let's say the same couple instead choses the following:
1. First choice is same program in NYC
2. Second choice is differen progs in NYC
3. Third choice is Radiology in NYC, no match in IM (presume scramble in NYC)
4. Fourth is Same prog in SF
5. Fifth is diff progs in SF
6. Sixth is Rads in SF, no match in IM
7. If none of these, then no match for either
In that case, you enter the following:
A A
B B
A B
B A
A X
B X
C C
D D
C D
D C
C X
D X
It is this kind of control of the match that makes couples matching so powerful. It also makes it dangerous -- you can prevent a match (ie the above match lists prevent one partner from matching in NYC and the other in SF). As posters have mentioned, if this involves sacrifice you need to measure the importance of the relationship against any possible sacrifice created.
The statement above from McNinja:
McNinja said:
It didn't work for me, and some places, when called and asked what happened, stated that they couldn't communicate with the other departments about ranking. Sad thing is, each of us would have matched separately.
If both halves of the couple list all possible permutations, then this cannot happen. Again, the above examples prevent an NYC/SF match for the couple, but you could easily enter an "A C" match option to allow that if you wish.
Issue #2 Can the match somehow screw this up?
Quick answer -- absolutely no. The match is double and triple checked. The easiest way to check the match is to run it backwards -- no matter what order the match is run in, the answer should be exactly the same.
Issue #3 Can different departments talk to each other?
Absolutely yes, this happens all the time. However, in general most programs will not move people around much. In my own program, if we have a couples match with another program, we discuss it and I will move someone up our list to the top of their "tied section" -- when you're making a list that is 100's long, there are lots of ties.
Issue #4 Why doesn't the NRMP system allow couples to create rank lists in sync with each other?
No idea. Great idea. I plan to ask them that shortly.
Issue #5 What about this "Where's your ring?" question?
First of all, asking this question is illegal. That won't stop people from asking it, and reminding them it's illegal to ask probably won't help your chances either. A non committal answer like "We are going on vacation in May and I think he's planning on asking me then!" is an idea. It's not lying if you're actually on vacation in May, is it?
