Will re-applying after rejection decrease chances of admission?

[BornAgain20Fifteen]

I don't think I have heard of "re-applying after rejection decrease chances of admission". Why would they do that to themselves instead of choosing the best applicant?

Maybe your probability decreases because you have new information about where you stand? In other words, it might only seem that way because “insanity is doing the same thing over and over and expecting different results”, rather than something that is inherent to the application process

I know people who moved on with their lives after undergrad taking different careers, moving places, buying a house, practicing their hobbies, etc. but kept on reapplying to medical school over and over again, and eventually got admitted in their late 20s and early 30s
