It's like none of you understand the concept of odds or probability.

you can't apply pure mathemetical odds if i can make up the rules of the game on the fly

take his "inside straight" example. if, in the middle of the game, i say you can complete a straight if you hit a card at OR 1 slot above/below the number needed for the straight, your odds just changed significantly (by 300%)

that's the issue here b/c Nate is using bad data to create the appearance of objective analysis

Just because you can't ever be "proven wrong" doesn't mean that there's not value in attempting to anticipate future events based on past events.

but this is only as valuable (in real time) as the data fueling your modeling is

i'm not arguing "wrong" or "right" (b/c as long as Silver never goes to 0% he is always "right"). just saying the probabilities are garbage b/c they're being calculated by garbage, biased input

when you have a series of events like poker hands

Polls have no value whatsoever besides pushing a narrative?

Do you think any of these clowns are objectively seeking truth?

there's 1 clear example of bad input to a 538 model: the 2016 presidential election. they've proven to do a good job predicting results over the last decade.

538 has never tried to be "wrong" or "right", just apply probabilities. They also never give 0 because it's impossible to give zero, the mathematics of probability prevent a 0% chance in an election based on people voting when they haven't asked every single one the voters. They don't avoid saying 0 to avoid being wrong, it's just math.

and i have defended them on here within the past week

but, if Nate is really using his own subjective grading scale to rank polls, then he's making subjective evaluations. and we all know those decisions are primed and biased to hell (not due to Nate; due to human nature)

which was such a blow to the system it should have invalidated this talking point entirely

however, we're back again...with...mirrored polling to 2016. if Nate were this robot "just entering data" then he'd have to account for this. he has...just not in the data and modeling he presents (he saves it for words on his podcast where he basically admits he knows the polls are bullshite but throws up his hands and goes "oh well" while giving Biden higher odds than he admits he should)

And yet you said he “aced” 2012. Isn’t that a claim that he was right?

i listen to the 538 podcast a lot

time has melted together for me since Laura but i think a few weeks ago they had a conversation about what a trump win does to polling and they got into this all. this was back when biden was WAY up with some crazy projections (like that NBC poll)
