  • I think you’re missing the point of predictive modeling. It’s probability of separate outcomes is built in. This isn’t fortune telling, there is no crystal ball. Two predictive models can have different predictions and they both may have value. Just like separate meteorologists can have different forecasts, but predict accurately the same amount over time, all be it at different intervals. IIRC, the average meteorologist correctly predicts rain over 80% of the time. They are far over predicting by chance. But if you look at the forecast in more than one place you often get slightly different forecasts. They have different models and yet arrive at similar conclusions usually getting it mostly accurate. It’s the same with political forecasts, they are only as valuable as your understanding of predictive modeling. If you think they are intended to mirror reality flawlessly, you will be sorely disappointed. That doesn’t make the models “wrong”, it doesn’t make them “right” either. They are just models that usually predict a probable outcome.


  • His model has always been closer state to state, election to election than anyone else’s, which is why people use his models. He is basically using the same model and tweaking it each time, you make it sound like he’s starting over from scratch. When Trump won, none of the prediction models were predicting he would win, but his at least showed a fairly reasonable chance he could. His competitors were forecasting a much more likely Hillary win while he was showing that trump would win basically 3 out of 10 times. In terms of probability that’s not a blowout prediction. His model was working better than competitors. Additionally, he basically predicted the battleground states within a half percentage iirc, that happened to be the difference between a win/loss in some states.

    So he has exactly one chance to get it right.

    You’re saying it hitting one of those 3 of 10 is “getting it wrong”, that’s the problem with your understanding of probability. By saying that you’re showing that you don’t actually internalize the purpose of a predictive model forecast. It’s not a magic wand, it’s just a predictive tool. That tool is useful if you understand what it’s really saying, instead of extrapolating something it absolutely is not saying. If something says something will happen 3 of 10 times, it happening is not evidence of an issue with the model. A flawless model with ideal inputs can still show a 3 of 10 chance and should hit in 30% of scenarios. Certainly because we have a limited number of elections it’s hard to prove the model, but considering he has come closer than competitors, it certainly seems he knows what he is doing.




  • but it does mean that Boeing got something wrong.

    Comparing it to Boeing shows you still misunderstand probability. If his model predicts 4 separate elections where each underdog candidate had a 1 in 4 chance of winning. If only 1 of those underdog candidates wins, then the model is likely working. But when that candidate wins everyone will say “but he said it was only a 1 in 4 chance!”. It’s as dumb as people being surprised by rain when it says 25% chance of rain. As long as you only get rain 1/4 of the time with that prediction, then the model is working. Presidential elections are tricky because there are so few of them, they test their models against past data to verify they are working. But it’s just probability, it’s not saying this WILL happen, it’s saying these are the odds at this snapshot in time.



  • I am 6’ 6" and most of my life I’ve been between 145 to 165. So incredibly skinny, always under weight. I never struggled with women as an adult, but I also didn’t chase too many shallow women. When I was young i certainly got told by a few that they weren’t into skinny guys, but it was almost always by people that were incredibly socially controlled people, the type to “keep up with the Joneses” so to speak. Once I stopped chasing after people for the wrong reasons things improved dramatically.

    Do you have close friends that are women? I wonder if there is a communication aspect to this if not. Do you date outside your culture? I grew up around mostly white rural Christians and they were more judgy about being skinny than other cultural groups, in my experience. Maybe something about rural people doing a lot more hard labor and it being culturally homogeneous.







  • I don’t doubt anything you are saying, but it’s worth mentioning that (iirc) 80%+ of severe injury and death on a bicycle is caused by motor vehicles, or complications of motor vehicle involvement. People very rarely have severe injury or death on dedicated bike infrastructure. The primary risk on bicycles is motor vehicles. If you remove motor vehicles, there is still risks, but someone might decide that risk is low enough to forgo a helmet. I don’t feel those people should be called stupid for their choice.

    There is considerable evidence that everyone wearing a helmet in a car would save vastly more lives and prevent severe head injury, and yet pretty much no one even considers that as a normal thing to do. The bike helmet thing is therefore just as much a cultural attitude, as it is about safety.

    I still use a helmet, and more importantly, visibility gear, on my bicycle in 100% of my rides. I’ve never worn a bike helmet walking or driving in a car, even though my cousin died from a head injury getting hit by a car while walking and my grandma-in-law died of a head injury in a car…

    A helmet is only needed if you intend to spend significant time in traffic. Most of the world doesn’t use one.

    The math behind using one is a lot more on the margins than people realize. In order for it to save you, it first has to prevent a head injury, and then prevent one that is in the range of severity that makes it useful. The vast majority of bike injuries won’t fall in that range, they’ll either be related to another part of the body, or in the case of high speed crashes from a car, too severe for a helmet to matter. But helmets do give people a false sense of security. Statistically people ride faster and take more risks with a helmet on. Lastly, again statistically, the visibility gear you put on yourself while riding does more to keep you safe in traffic than a helmet. Lights, reflectors, reflective vest, etc.

    All this to say, the religiosity with which people proselytize helmets is misplaced. I still wear one, but I don’t judge people who choose not to.






  • Seriously, that was my only comment and now I’m also a rapist according to you. This is something else, I can’t say I’ve ever encountered someone this toxic on Lemmy since I’ve been here. You extrapolated all sorts of things I never said from 2 sentences.

    Not that you are remotely deserving of a respectful response at this point, but I’ll still give you my thoughts:

    I’ve been sexually assaulted and have had people close to me be sexually assaulted and raped. The insinuation that I am a rapist would be personally harmful to me and retraumatizing if I wasn’t aware that you are doing this because you are unable to articulate your opinions on the matter effectively, so you resort to insults. I totally understand the visceral need and desire for vengeance and justice when you or someone close to you is the victim of vile acts. There is someone I grew up acquainted with that if I saw them again in person I would have an intense desire to cause physical pain because of what they did to people close to me. I totally understand the desire for vengeance, and I suspect everyone else on this thread does too.

    With that said, when societies make rules you have to decide what the goal is. Is the goal vengeance and punishment, is the goal a better future for society in general, or is it a little of both. We have the sum total of human experience to look back on, we can see what societies systems of punishment result in better outcomes for society at large. We know what systems of punishment result in recidivism more often, what systems result in rehabilitation more often, and we know what systems perpetuate a cycle of violence that never ends. We don’t rehabilitate criminals and sex offenders for their sake, we rehabilitate them for societies sake. Because we can conclusively show that if systems of punishment make it their goal to rehabilitate instead of get vengeance, it usually breaks the cycle of violence whether it be physical or sexual. You’re basically saying you would prefer vengeance, even if it is at the expense of sexual and physical violence being perpetuated through society generation after generation.

    I strongly suggest you read this article: https://www.firststepalliance.org/post/norway-prison-system-lessons#:~:text=Prisoners in Norway lose their,crime rates in the world.

    Norway has the lowest recidivism rate in the world exactly because the treat their criminals like human beings. Guess who wins, all of the non-criminals that enjoy one of the lowest crime rates in the world.
