The south is a nigger infested shithole, and all of the supposed "based and redpilled" southern conservatives are all christcucks and civnat neocon zionists who support Ukraine and Israel because they think Russians and Palestinians are all antisemites who hate the LGBT community and "American values".

The most based and redpilled part of the country are small towns in the Midwest and New England.

>>16143950
They're headed south not to live in a mobile home in the woods, they're headed there to attend the least pozzed universities. Schools in the south are woke but nowhere near as much in other parts of the country. That's what is attractive to them and not the irrelevant stuff you babbled on about.
>But we have schools in New England too.
You and I both know they're max woke, which is why they're being rejected. Same for Midwestern universities, which pride themselves on bringing coastal values to "fly over country".

Hello, /sci/. I'm strongly in the belief that we learn best through doing things ourselves but I'm afraid that I'm entering a lab course this fall where it's very likely I will be assigned to a group with 1-2 partners. Should I just tell my partner that I'll do all the work myself? I'm kind of a perfectionist and if my partner screws that up, I'll probably drop out of school yet again.

You're probably trying to bait me into a parallel, in that car evolution is influenced by man. One could say that God influenced ours. We can observe evolution from microorganisms and fruit flies as a result of their environment.

Yes it's true, but little changes in concentration can have large effects when compounded over time.
But also climate advocacy is gay since we can cool the earth with aerosols and make clean basically free energy with nuclear. But we wont ever do that because you can't make money with that.

>>Like I ALWAYS say. Find out the weight of the USS Enterprise 1701-D and then divide it by the cargo capacity of Musk's Starship. Even if his cock rocket worked perfectly, and it won't, it's impossible to make one starship with all the Space X launches ever. Can't be done. If you can't build a ship to house and feed and keep safe 150-300 people over 3-6 months in space then you can't colonize a planet. It drives me insane how blind and easy to fool you hairless apes are.
I don't know what "make one starship with all the Space X launches ever" is supposed to mean, but you should know that colonizing Mars is just a recruiting gimmick for SpaceX and Starship's real purpose is to launch BRILLIANT PEBBLES!

Yeah, I have USS Enterprise 1701-D in my calcs. It's 190,000 tonnes, and if Starship can lift 150 tonnes, that's 1267 launches. With the 1/day cadence, and 1 new starship added monthly, that will be only 8 months after Starship gets online.

let's check case n:o 6

there is 15/21 that the first red came from case where n>3. from these cases its always more probable to draw red again
>>
>>16143891
The odds should add up to 1/2 because you have a 50 / 50 chance of drawing a red ball first. Similarly, if you draw a green ball, you have a 66.66 percent chance of drawing a green ball the next time.
>>
>>16143911
Let's go over it exhaustively. For every 105 red balls we get on our first draw, we expect:
30 red balls to yield another 30
25 red balls to yield 20
20 red balls to yield 12
15 red balls to yield 6
10 red balls to yield 2
5 red balls to yield nothing

So 70/105 balls will give us another red, or 2/3. Erry tiem.

Every time i interact with an extremely attractive girl my charisma short circuits and everything I say sounds like a lobotomized monkey trying to sound interesting. But when I interact with a girl I consider at my looks match or below, all my jokes are perfect and my responses are easily fabricated? It completely automated, like some kind of counter in my brain is screeching, OH SHIT ATTRACTIVE FEMALE DETECTED PANIC MODE ACTIVATED. I fucking hate that shit. What biological benefit to spazzing out like a total fag when the goal of human biology is supposed to attract the highest value woman possible to produce offspring with if my stupid monkey brain freaks out in direct proportion to the attraction I feel to the girl?

Are we twins? Also if you are aspie then your sincere lack of fucks makes you that much more attractive to women. I can’t tell you how many times I literally didn’t care about a girl and lived my life, only for her narcissism to translate that into “he’s playing hard to get so I must get drunk and sleep with him at a party”. Autism may have fucked me over a lot in my life for not getting the social games, especially in the office. But it actually helped me get laid a lot in my life so it all balances out. As it turns out women really are all the same, regardless of how attractive they are. Once you see how deeply insecure and attention seeking they are the intimidation factor is gone and you remember she’s just a child.

Unsurprisingly, a poor understanding of the problem also results in a faulty analogy
>>
>>16143958
Where is the flaw?
>>
>>16143968
Firstly, there are three women, not two. Secondly, you know that one of them is 100% into you, but you do not know which one. Maybe you're meeting a blind date who is as into your obscure weird fetish as you are but stupidly forgot to agree on a token of recognition in your eagerness to meet. You also know that any other women will be repulsed by your sick fetish. If you broach the subject of your fetish with someone who is not into it, she will kick you in the balls, neutering you, and subsequently have you arrested, ruining any chance you have of getting laid. However, you have no other way of ascertaining her identity. With nothing to go on, you strike up a conversation with a random woman Whilst she is your captive audience, another woman gets up and leaves. You know this cannot be the woman you were intending to meet; she will never meet another man as sick as you. One other woman that you didn't talk to is still waiting by the bar.

So, do you bring up your fetish to the woman you're talking to? Or do you go to the woman by the bar and apologise for the confusion? What if there were four women in the bar, and two of them left, besides one by the bar and the one you're awkwardly making small talk with? What if there were five, and three of them left over the course of the evening? What if there were fifty women at first and at the end of the night there's just two left, the one you're talking to, and another who's been sitting by herself all evening?

>>16143975
Yeah that's the Monty Hall Problem alright but I'm just pointing out how absurd it is that the success probability of a group concentrates into one choice once the rest have been eliminated. Isn't that the standard reasoning behind switching?
>>
>>16143978
It only happens when there is a specific reason for it. Probability is not an inherent property something possesses, but an expression of our relative certainty about it. So as women leave the bar, it becomes more likely that the ones who stay behind have an interest in you.
