I took both and I argue that the MCAT is a higher stakes exam. An insanely tiny minority of US MD students actually get a sub-200 score. Essentially every US MD or DO student who takes the step will end up practicing medicine.
And if you score average (230) you have a legit shot at a wide range of specialties that are not ortho/ENT/derm type. And guess what, most med students are not after those anyway.
You do average on the step1, you'll be OK. You do average on the MCAT (25), well go teach high school biology.
The fact that MCAT allows retakes lowers the stakes tremendously and I'll accept that argument. However the argument that MCAT allows unlimited study time is not related to the stakes of the exam, rather that is related to degree of difficulty. You can't conflate the 2.
You seem to be very fixated on justifying your argument because of the high pass rate step 1. So let me ask you:
1. A soccer player with a >95% penalty shot success rate is up to shoot. It's the finals of the World Cup and if he makes the shot, the team wins, if he doesn't his team has a 95% chance to lose. Is that a high stakes scenario?
2. A patient needs to undergo a procedure/surgery with a success rate of 95% throughout the country. However, if there are any complications, this can lead to death, paraplegia, or other consequences that drastically changes the patient's lifestyle. Is that a high stakes scenario for both the doctor and patient?
Given the moment, they're both incredibly high stakes. But if we use your logic, neither of them are high stakes because of the historically high success rate. 20/20 hindsight based on statistics does not always tell the full story. Reality is, every med student that goes in to take step 1 has a probability of failing the exam. Whether it is a high or low chance is up to the individual, but there's a chance to be in some heavy debt with a not so bright career path.
You will then proceed to counter this analogy with:
1. Despite all of the soccer team's hard work, legacy, and the hopes of a nation behind him, if the player does miss the shot, he's still making millions of dollars. NBD right? No need to account for the fact that he will shoulder the pain of missing that shot for all of his career.
This is your "scoring average or slightly below average step 1" argument.
2. The second scenario is what YOU deem to be the failing MCAT scenario. Essentially "bum life" and "go teach high school kids" argument.
This is where your issue is. There are plenty of successful individuals who transitioned out of medicine and live an equally or more successful life in another field. The individual may become an entrepreneur or investor and make more than you would ever make as a physician in a couple of years. Or they could go into research and fit very well into that environment. They get millions of dollars of funding and are just as successful. There are plenty of researchers in my building with this kind of background.
For an individual who just went through the process of taking and waiting for step 1 results, I had a lot of sympathy and understanding for you. But each ignorant and arrogant comment that you spout just highlights how flawed your thinking is. There will be plenty of DOs who score higher than you on step 1 and there will be plenty of people who are successful just because they don't have an MD next to their name. It's time to get off that high horse and treat people in different fields with the respect that you want to receive as well when you become an MD.
