> Maybe colleges can just accept the best students If you want to see what a world where universities do that, check Europe in the 11th century. You might just like it

And if you want to see a world where colleges accept everyone, without requiring a minimum qualification, look at our current system: over 50% of students lack proficient literacy skills. It shouldn’t be controversial to recognize that some students are not capable of success in college.

do you mean intrinsically not capable, or systemicaly not capable.

I once listened to a scientific presentation that was interesting, but I don't remember the professor's name or whether his hypotheses have panned out long-term. That said, he flipped the script on the usual take on research trying to understand why some people respond to early adversity by going off the rails while others seem to trek through it relatively unaffected with positive outcomes. Usually the research focu…

Almost anything can be made sense of from an evolutionary perspective. Often even the opposite of what's being observed. Can be a fun game to play. The corollary is it's not useful for vetting theories for plausibility.

Maybe colleges and scholarships that make admission decisions based on adversity can someday objectively measure it by DNA methylation. Also for reparations or welfare benefits. It would seem to be a more direct proxy than melanin pigment density. But on the other hand, adversity does not equal disadvantage, and in fact the trials that leave those marks -- beneath some threshold -- may bestow an advantage over unstre…

Since when has science stopped someone who wanted to use DNA to assign someone a fixed role in society?

sounds like he didn't say much, saying either you overcome adversity or you don't.

Whats the pitfall when research like this doesn't account for side effects like if you had early adversity, usually your nutrition, physical environment can also have a big impact across your body, vs people without adversity and had bad nutrition/enviroment.

In a nutshell, is this basically "stress the part and it wears out faster"?

It’s more like “stress the part and that part will change its internal maintenance processes, with some ripple effects across multiple parts”. They didn’t even find a consistent stress=aging pattern across multiple tissues.

No, the article specifically mentions that some parts appeared to experience the opposite of accelerated aging. Presumably that means the “parts wore out more slowly”.

You might be interested in “hormesis”, a vital aspect of Life’s resilience, in which (some) stress improves a system.

Maybe colleges can just accept the best students and do their job of educating them instead of arrogantly appointing themselves as saviors and righters of all wrongs in the world.

Higher education is the most potent tool for breaking the cycle of poverty. Your plan would lock people into the cycle of poverty for generations. Besides, how do you even define "best student". One that scores the highest on the SATs and has the highest high school grade? There's so much more to being a good learner than having the opportunity to get high grades and high test scores.

It's the opposite. Gatekeeping employment on that stupid credential is the best way to keep people in poverty.

In the USA, at least, "every student college bound" has led to colleges being simply more high school but at an enormous cost of creating indentured servents. It will be very hard to to force colleges to downsize to the appropriate population count. Lots of prestige and money on the line

It would actually be very easy. Just stop subsidizing them with student loans from the government.
