I'm sorry, idealist, but I don't get it. Are you hoping to have your suspicions about psych being an easy match confirmed so you can shirk studying with a clear conscience? Are you looking for motivation TO study? The very fact that you made the post suggests that you know you really SHOULD be studying, so live up to your name and get to learnin' already! But in case you still wanna know:
Psych is indeed a pretty easy match. Interviews feel more like being recruited. I just matched at my first choice and got interviews everywhere I applied, mainly very competitive programs. I had 240s and (I think) good letters and (I know) good med school grades. I go to a fair-to-middling med school. So you could probably do fine with less than 240s. I have honestly never heard of a US grad not being able to match in psych, although I'm sure it happens now and then. But here's the rub: note that I and many others on this thread got every interview we applied for. Now, you can always screw up the interview (I know two AOA students with very high boards who had to scramble this year) but the point is you GET the interviews. And from what I hear, there's no (single) better way to get interviews than to kick the living **** out of Step 1. Remember, you (hopefully) only do this interview and match thing once, so don't leave anything on the table - why have regrets? Why wonder during your nastiest call nights, at your lowest ebb, if things would have been better had you only gotten that ONE interview that you didn't because you screwed around instead of studying for Step 1? Of course, things probably WOULDN'T be better at that program, but if you get the interviews you won't have to worry about it!
Also keep in mind two other points - when you hit clinics, you might fall in love with, say, radiology (like I did). I decided to go for psych anyway (I like people slightly more than cushy chairs and big monitors) but I had the option if I wanted it (there's a sub-point here, which is that if you are too lazy to study for Step 1, you are far too lazy for most specialties. The few possible exceptions are generally specialties that require pretty high scores in order to match. A real conundrum.).
Also, you can definitely fail Step 1 if you slack off. It happens. It happens to people who are WAY too smart to go around failing exams. And that ain't gonna help you match in ANY specialty, esp. if you want to be in a high-quality academic environment.
That's it! Go study!
