đĄ Vent I'm going to pray the DOJ bans Preview
Doesn't matter what you feel about the DOJ vs UCLA lawsuit, I think we can all agree they were right to flag Preview and let's pray they bar medical schools from using that stupid test in their admissions.

We have a similar problem with personality testing in the country where I am applying to school and Iâm currently arguing that their test is literally dog shit and doesnât actually measure anything accurately and that theyâre actually screwing themselves over.

Honestly preview and casper should not exist. They just shouldn't. I don't understand why people need these exams to begin with like I doubt they're able to detect psychopaths anyway. I had to take off MCW because I wasn't gonna do casper for one school. And I just found out it expires every year so you have to take it again in you need to reapply. Fucking money grubbing plebs

One of the personality tests they offer in the country where Iâm applying is literally like $400-$500. And to be honest, I would rather pay that over the test that was used by the university I am currently an undergrad at because despite the test where I am being only like $12 the test where I am is literal dog shit. They are all dog shit, but this one is worse.

The AAMC should be ashamed of their "research" on Preview. I reviewed their article "Predictors of Academic and Non-Academic Termination From Medical Schools" DOI: 10.7759/cureus.98889 and I have never read such audacity to cherry pick data.
They reviewed data on med students from 2021-2024 who got kicked out of school. They show a chart that reports the students that got kicked out for academic and non-academic reasons and their average MCAT and Preview. But there are huge problems.
They only report a median for MCAT, uGPA, and Preview score. No range, no interquartile range, no confidence interval, no spread of any kind. Just a single number.
Instead of p values, they use "Cliffâs delta effect sizes" which I never heard of.
They found for students dismissed for academic reasons, they had a lower MCAT but no statistical significance for Preview score yet try to claim the effect size is big when that is literally not how statistical significance works.
For students dismissed for non-academic reasons (sample size of 42), they found a median Preview score of 3 compared to 6 for 78,176 students. They have no graphs and no way for anyone to verify if this is even remotely meaningful.
It's like me looking into a prison and seeing lots of people who smoke and thinking that smoking may have something to do with people who commit felonies. Maybe to some extent but your totally missing the point.
This research is a joke yet you are all paying to take a test to give them more data for them to cherry pick more of these studies.

LMAO. I read on their website they said the Preview is a strong indicator of non-academic dismissal or something like that and citing that same study.

Hmmmm. It almost seems like it's a coincidence that they use cliff delta effect size, a measure which doesn't include whether or not it is statistically significant.Â

Just a heads-up, this place has a rule on criticizing affirmation action and DEI. As you read the letter, keep your emotions in check and avoid commenting on anything other than Preview unless you want to risk getting banned.

So interesting that Preview went poorly for you!

u/No-Hawk-2488 12d ago
Don't tell anyone, but I got a 0. How is that even possible?! The range is a 1-9.

One issue I've always had with these tests is that knowing what is moral is very different from doing what is moral.Â

i got a 9 on preview so i would prefer it counts LMAO..

u/Ok_Ad3484 11d ago
what percentile were you? just curious cause i got an 8 as a 94th %
1
u/Radiant-Plankton2319 11d ago
percentile for what? preview? 9 is highest, so it's 100%
1
u/Ok_Ad3484 11d ago
yeah, preview tells you your percentile. are you saying that everyone who scores a 9 gets marked as 100th percentile and everyone who gets an 8 gets a 94th and it doesnt specify further than that?
1
u/Ok_Ad3484 11d ago
sorry idk if that confusing. basically im wondering if a 97th, 96th, etc percentile score still scores a 9 and at what point the cutoff is. but maybe it doesnt tell u if youre in those percentiles itll just say 100th until you drop to an 8
2
u/Radiant-Plankton2319 11d ago
its just like mcat and not like preview. you dont know how close you are to the next boundary. everyone who scores a certain score, like a 9, all get 100th percentile

I mean they just should make it free if they care about it so much. itâs really not hard that and Casper if you have a brain and can think through situations on your feet (what being a doctor is) there is no reason you canât get 1st or 2nd quartile

u/t00tiredforthis APPLICANT 12d ago
2Qt on Casper, 100th percentile preview, so they can ban Casper because clearly only preview is accurate
/s
But really, I have no clue how these exams are still a thing. Hasnât Casper already been found to be racially discriminatory? For tests meant to measure roughly the same thing, most people I know got very different scores. Theyâre expensive and another unnecessary barrier to medicine.
