They might that actually brings up an interesting question I wonder how many students actually retake the LSAT?
Your logic that a LSAT taker who was overconfident on their first try could just retake, but in reality imagine the majority of LSAT takers give it one shot and that is it. I have no evidence to back that up, but it would be interesting and actually objective stat as to whether someone retook the LSAT.
Definitely a strong proponent of retaking the LSAT.
First time I took a practice LSAT blind without any prep I got a 145. I took the Kaplan course which was a 2 or 3 month course but it only administered a total of 3 full length practice LSAT tests during that time, which included the first one that I took blind. Long story short, I got a 145 on the first one, a 145 on the second one, and a 145 on the third one. Took the real thing a few weeks later and -- surprise surprise -- got a 145. Shocker.
Made my applications and barely even got the worst of the worst schools to write me back. Got maybe one or 2 acceptances from a few bottom of the barrel law schools and so I decided to sit it out for a year and retake.
Decided to take a different course on my next run since Kaplan didn't exactly do anything for me. A few days before the class (Princeton Review) was supposed to start I get a call saying that there were not enough people in my area to justify having the class so they cancelled it. I was panicked at the time but it actually turned out to be a blessing in disguise because in my panicked state I went out and bought every LSAT book known to man.
I studied each section of the LSAT every night on my own and during the weekends I took a full length practice LSAT on Saturday and Sunday. By the time I took the actual LSAT, I had taken so many practice LSATs that I could actually tell which section was the experimental section because it was unlike anything I had ever seen before.
Ended up getting a 162 on my retake LSAT.
And that is how I Forrest Gumped my way into law school.
But seriously, I strongly recommend that people really consider retaking the LSAT even if it means sitting out for a year. As we all know, law schools only care about 2 things: GPA and LSAT. To the extent you can increase both then you increase your options tremendously.
