There's definitely a genetic component but it would be interesting if those environmental factors impacted prevalence or severity.
Autoimmune disorders in general might be worse/more common in countries where kids grow up in clean environments. There's already some discussion on this with regard to allergies that I think has some credibility.
The Piazza post isn't publicly viewable, but I'm surprised you had this experience at MIT. The majority of classes I took had a ton of materials online and there were few instances where I felt I needed to go to class purely because of an attendance policy or a reluctance to share materials. Office hours are designed to be 1 on 1 for educational reasons, but other students collaborating at office hours (or outside of them) was encouraged on psets. I wouldn't expect any of this to be worse post-COVID either. Maybe a course 8 issue? But I'd be sad to hear this was the case now with 6 or 18 because it certainly wasn't in the past (and MIT was way ahead of peer institutions on this historically, in large part due to OCW)
I don't think "BMW repairs" is the main source of stress for high income people lol. I don't know whether it is fair to compare stressors across such different groups, but regardless I don't think it's fair to caricature what high income workers might be stressed about. One of my friends that happens to drive a BMW is a cardiac surgeon, and when he gets stressed over work I can guarantee you it is not about financial implications.
In general, management level decisions can affect entire teams of workers and have downstream impacts on products used by millions of people. That is a form of pressure. So is the way pro athletes can be put on the spot, and it's not like their output has huge "real world" impact.
Yeah, obviously we'd all rather have pro athlete stress than single working mom stress. But there's 0 reason to strawman what that stress is.
That's not Jane Street's process at all. I know first hand people from schools you've never even heard of that got internship offers, and I also know first hand people from MIT that got resume screened out. I'm not going to claim that there is no school bias at all, I don't know the finer details - but it's definitely not explicit as you describe. There are a lot of comments all over the internet (including this thread) from people at non-target schools that were interviewed.
There are some trading companies that do seem to legitimately do that kind of filtering (Two Sigma's application has a drop down menu for school with like 10 options and then "Other", DE Shaw asks for your SAT score, etc.). So I can see where the idea came from, but it's not true of JS.
They don't discriminate against good public CS programs though? There are many interns from Berkeley for example. There also aren't that many SWE interns from e.g. Harvard - there are a lot of trading interns from HPY but that program recruits heavily from math departments, not just CS.
I'm not sure if people ITT are mixing up trading with engineering or projecting old Wall Street biases onto Jane Street, but it's just not true that they prioritize what school a SWE went to. I'm not claiming they pour recruiting resources into Mediocre U, but they don't automatically filter out any schools, and there aren't any schools that get an automatic interview either.
And most relevant here, any school bias that does exist is related much more to the CS department at that school than any kind of archaic prestige/exclusivity factor. Waterloo and CMU are among the most represented for SWEs there - very good schools but not exactly global brands.
Most of the less prestigious 4 year institutions aren't functionally cheaper than MIT though, i.e. once you account for financial aid. The average tuition paid at MIT (and other "elite" schools) is lower than it is at the majority of private schools and even out of state public schools.
The sun sets where I am at ~430pm during the winter in standard time. I don't really see how having the sun set at 530pm instead would have a substantial effect on bedtime. There is so little sunlight in the winter that work/social life are what drive wakeup and bedtime. I imagine this isn't as true in India. Is there any research that accounts for the actual length of daylight available?
It depends how much time he spends per day, no? I always thought of Duolingo as something you do in 15 minutes of downtime here or there. Nowhere near the level of time commitment that a class would be.
He didn't use any loophole. He didn't make more than the allowable yearly contribution, which is small. If someone can turn that into billions good for them. The vast majority of wealthy people could not, hence why this is a weird anecdote like OP was saying, not an actual problem with tax code. And there are many such actual problems we should be focusing on.
You can only put earned income into a Roth, you can only put up to 6K per year, and you are only eligible to put anything at all for a given year if your total earned income was below a fairly modest threshold. Roth IRA already has plenty of restrictions. The fact that one man happened to be some combo of smart/lucky to make the modest initial investment turn into billions is definitely not an indication of whether the Roth is problematic. I think the parent may be confused about the exact details of a Roth.
We have 2 other vaccines that do not present this risk. It seems pretty likely the issue affects mostly younger women, so I don't see the problem with encouraging that demographic to get a different vaccine if they have reservations about J&J. To me that seems like the more practical approach as far as safety of all involved AND actually convincing people on the fence to get vaccinated. Let's stop with the "all vaccines are the same" bullshit.
The link above states 3 women so far have died from J&J and 7 more remain hospitalized. If you do demographic-specific division and compare that to the likelihood that same demographic would die from COVID, it seems unclear to me that young women would come out better getting the J&J vaccine. Both things are very unlikely to happen, but ultimately it's easy to get a Pfizer or Moderna appointment these days (at least in my area) so I don't see the point in trying to pressure people into getting J&J if they're concerned about that specific vaccine. Pfizer/Moderna are probably more effective anyway.
Another personal anecdote, but not only do I consider "guys" gender neutral, but I found it kind of alienating when a few people clearly stopped saying "guys" shortly after I joined the team. I was the only woman on the team that summer (internship), and I think they were just trying to be nice, but I don't like when attention is called to gender in the workplace. The more (actively) aware I am of being "different", the more it impacts interactions.
I will add they did this experiment partially in response to an academic study that found viewing happier posts on Facebook made people sadder (explained mostly by FOMO).
FB was trying to refute that, and their study was more technically rigorous, but the outcome they were measuring doesn't actually refute the original claim at all IMO. People writing more happy posts on FB does not indicate they are actually happier, it could also be that they wish to broadcast more of their happy moments, or perhaps even just pretend to be happier, in response to the attitude of their feed.
