Someone tosses a coin ten times; it comes up heads every time. What's the probability it comes up heads on the next toss? (Pretty darn high—part of @nntaleb's work is unprogramming you from your high-school rules of thumb.) Now consider the (related) Gambler's fallacy...

 In this case, it's a theory about compensation: the worse one's luck is, the more likely it is to see a reversal. On the surface, it's irrational. The more bad luck you have, the more you accumulate evidence that the system is rigged.
But there's also an anthropic component. If the luck is bad enough, it starts to become inconsistent with your survival. You've accumulated evidence for correlations in the environment, but these correlations (may be) inconsistent with (people like you) being in this environment.
An example. You're in a city where everyone takes public transport. You encounter a string of bad delays. It's reasonable to conclude they'll end—otherwise people wouldn't take public transport. It's unlikely that you happened to show up right when the network collapses.
Of course, that's a bad heuristic in a casino, which relies on a constant influx of losers. But in other environments, particularly with persistent populations and no evidence for sudden changes in the underlying laws, it makes sense.
Another example: the three-card monte scam in a big city. You meet some guys on the corner, who convince you to go in on the game. You win, a few times. The more you win, the more you ought to be convinced that your luck will turn. Otherwise, how are these guys there?
(In this case, the anthropic reasoning concerns the scamsters—it's unlikely that you showed up right when their operation starts to fall apart.)
The general principle, which again is due to @nntaleb, is a new kind of failure. The "IYI", intellectual-yet-idiot. IMO, this is driven by standardized testing—we started to promote people on the basis of their ability to internalize fake-but-difficult-to-master rules...
In a previous cycle, the British ran their empire by fast-tracking twelve year olds who could master Latin grammar. The ambiguities of interpretation make this a much better idea than the SAT version, where one learns more abstract "grammars"—e.g., integration by parts.
Everything can be degraded, of course. When I give CMU students the coin-toss problem, it's usually unfamiliar enough that they're thrown back on a more complex, and life-integrated, form of reasoning. But ask that question enough, and tutors will arise to teach the solution...
...which negates the original value of the puzzle. (BTW, nearly all the students "get it", which bodes well for our future engineers.)
A final thought on this, before I get back to my real work. If you pose this kind of problem as a teacher, there's a second level to what's going on: your students are also modeling you! (and your class.)
i.e., they're asking themselves—is this a class where we're all living in la-la land, or is there some substance here, some connection to our own lived experience?
So, yes, I'm proud that most of my students get it. :)
This is lovely—yes! "I can't be the only idiot" summarizes why we keep waiting for the train with rising hope. https://t.co/s3d4aFg7Tv
You might also connect it to the bulk-vs-long-tail. "I'm not the only idiot" is true when there are repeated tests of the system of similar magnitude.
OK, truly one last thought. A scam is more likely to succeed if you're doing something new, but can convince people you've always been around, that this is "normal". Certainly psychologically obvious, but it's fun to look at it from the point of view of rational analysis.
(In the case where the scam operates by inducing the Concorde/sunk-cost fallacy—slowly extracting money from the person, who continues to believe in a final payoff.)

On Bayesianism, the Many Worlds Interpretation, and personal identity.

Some thoughts worked out in a letter to a friend, which is the kind of thing you do when off Twitter for a glorious week. (🧵)

“Chance is ignorance”—the Bayesian story; all probabilities represent states of mind, not states of the world. One *could* put (some) chances “in the world”, but let’s take Occam’s Razor seriously...

That the probability of a fair coin coming up heads is 50% simply means that marginalizing (tracing, as the physicists say) over the hidden facts leaves you, nearly, maximally ignorant of the outcome.

Quantum uncertainty (access below!) poses an apparent challenge to this story. There seems to be nothing to be ignorant about when it comes to (say) electron spin—there is nothing “inside” the

The electron is a simple object, in other words. So where does the uncertainty come from? One could follow David Wallace’s wonderful interpretation in terms of chaotic dynamics and decoherence, but let’s see if we can take another route...

"I lied about my basic beliefs in order to keep a prestigious job. Now that it will be zero-cost to me, I have a few things to say."


We know that elite institutions like the one Flier was in (partial) charge of rely on irrelevant status markers like private school education, whiteness, legacy, and ability to charm an old white guy at an interview.

Harvard's discriminatory policies are becoming increasingly well known, across the political spectrum (see, e.g., the recent lawsuit on discrimination against East Asian applications.)

It's refreshing to hear a senior administrator admits to personally opposing policies that attempt to remedy these basic flaws. These are flaws that harm his institution's ability to do cutting-edge research and to serve the public.

Harvard is being eclipsed by institutions that have different ideas about how to run a 21st Century institution. Stanford, for one; the UC system; the "public Ivys".

One thing that goes unremarked about Wikipedia: the vast majority of the content was written over 12 years ago—which means (given turnover) that the editors dominant today were not directly involved in that creation.

Put another way, the editors who built the dominant nodes in this network...


...have little overlap with the ones who made this much more recent managerial flowchart.


Internet time runs at hundred-fold speed—the difference between the people who painted what's in the Uffizi, and the people in charge of keeping those paintings from deteriorating. Very different tasks, and (one presumes) very personalities as well. @PaulSkallas?

This is a pretty valiant attempt to defend the "Feminist Glaciology" article, which says conventional wisdom is wrong, and this is a solid piece of scholarship. I'll beg to differ, because I think Jeffery, here, is confusing scholarship with "saying things that seem right".


The article is, at heart, deeply weird, even essentialist. Here, for example, is the claim that proposing climate engineering is a "man" thing. Also a "man" thing: attempting to get distance from a topic, approaching it in a disinterested fashion.


Also a "man" thing—physical courage. (I guess, not quite: physical courage "co-constitutes" masculinist glaciology along with nationalism and colonialism.)


There's criticism of a New York Times article that talks about glaciology adventures, which makes a similar point.


At the heart of this chunk is the claim that glaciology excludes women because of a narrative of scientific objectivity and physical adventure. This is a strong claim! It's not enough to say, hey, sure, sounds good. Is it true?

Donna Strickland, one of this year's Nobel Laureates, was not considered "notable enough" for Wikipedia as late as this May—reported by a number of sites, including the Independent. I dug into this a little. Here's the data—


This is the first deletion, back in 2014. A bit hard to read between the lines, but the basic story that an admin had Stickland's page "speedy deleted"—i.e., deleted without debate. The method was something called Copyright Jujitsu.

In particular, the admin had the page deleted not because of notability, but because it included a photograph of Strickland that had ambiguous copyright status. This is a method that people developed to get rid of content they didn't want, but also didn't want to debate.

"Copyright Jujitsu" because it is usually used against spam from companies; a PR officer uploads promotional material to Wikipedia. Instead of debating whether it's neutral, the admin can say "we'd love to have it, but the material appears to violate your company's copyright".

Usually the PR office and the IP office are separate in a company, and the idea of releasing promotional material under public domain is such a legal nightmare that the PR person goes away.

TRIANGLE MASTERCLASS - a thread.

what's the simplest, most effective method of trading a market that trends as hard as cryptocurrencies?

trendlines.

one trendline on its own is strong, but when you put two together you quickly realize just how powerful this simple tool can be.


i've been using triangles for as long as i can remember.

it seems dumb, and almost counter-intuitive to approach such a complex game like trading with such a simple approach like shapes...but maybe when markets start acting stupid its okay to dumb down our approach.

look, not all triangles are the same.

anybody can draw some lines on a chart any way they'd like. sometimes, we let our bias affect our charts rather than the other way around.

i personally have done this more times than i can count.

you see...triangles (and analysis as a whole) is not necessarily intended to make trading easier as much as it is to make trading simple.

you want a fluid bias that can change easily, rather than one relying on 10 steps of conflicting confirmation before entering a new trade

trendlines enable us to maintain a fluid bias.

i mean, how much simpler can it be than "above this line bullish, below this line bearish" ? 😂

one trendline on its own can be enough to make a good trade, but when you put two together it can turn a good trade into a great one.

@VentureCoinist @HypeBillion @MycolePawket If the whole world settled on one stablecoin, I'd agree with you. But stablecoins are always going to be tied to jurisdictions and counter-parties too. So it is unlikely one winner will emerge.

@HypeBillion @MycolePawket Today, one of the roles of the dollar is acting as an intermediary or bridge between currencies. For that role, its tie to the US jurisdiction is both an advantage and a disadvantage. Better US than a worse jurisdiction, but a pure digital asset is better still.

@HypeBillion @MycolePawket Imagine a future (maybe not so far off) where everything is tokenized and you can have your salary agreed in dollars but gold gets delivered to your wallet and you can buy groceries by selling tokenized shares of a REIT.

@HypeBillion @MycolePawket In that world, there will need to be concentrations of liquidity. You can't go from gold to shares of an obscure REIT by finding people who want to go those same shares to gold. The liquidity-concentrating asset likely can't be one country's currency. How could that be universal?

@HypeBillion @MycolePawket So, sure, if you get paid in dollars and pay your bills in dollars, it may make sense for you to use a dollar-denominated stablecoin for short-term holdings and payments. Absolutely.

While my time investing in crypto and previously playing poker has gotten me used to experiencing large daily personal net worth volatility, it's never a pleasant experience

Short thread (by my standards...) with some ramblings that help me get through it 👇

1/10 Imo, some DeFi projects represent 10-1000x upside opportunities

Obviously, like all of crypto, it is extremely risky and can go to 0. That said, given the magnitude of potential outcomes, it just doesn't have to succeed that often to make it a massively +EV bet

2/10 As with all early stage tech, realising these outcomes will require 4-8 year holds

Unlike early stage tech, crypto investors will have liquidity, i.e. the possibility, and thus the temptation, to sell

This is both a blessing and a curse

3/10 A look at any of the best performing public stocks will show you that you cannot have 10-1000x upside potential without volatiliy and occasional large drawdowns

Crypto, as early stage tech, is much riskier than established public companies and thus even higher vol too

4/10 Obviously, one should take advantage of this liquidity as it allows for rebalancing. Most importantly, it also makes outcomes less binary and thus less volatile than traditional VC

However, one should not let the liquidity take advantage of us

Will start this thread with a disclaimer. I have never invested a rupee in cryptos 😀

But I have studied bull and bear cycles and financial bubbles extensively. Saw 1992, 2000, 2008 with own eyes. The first one as a novice, the next two when I knew to analyze

The amount of chatter I am seeing in friends, family and social media about cryptos has gone through the roof. For everyone, it's a dream to make 100x or even 1000x easily. Basically, become stinking rich easily
( it never happens )

In any financial bubble, the top is made in extreme speed and violence. The distribution happens on the way down. Unless one saw the rates of 65k on bitcoin, one wouldn't buy at 30-35k or 20k. That 65k is an anchor point which leads to greed

During the tulipmania, a single piece of tulip reached a price of $750,000 in today's money. When we see that history, we think "what idiots". But consider this, as of now meme coins generated by someone in their garage are being traded at absurd prices


Then there is this joke called NFT. A piece of "digital art" basically made by someone on their computer ( who is not even a known artist) are being sold for millions of dollars

1)King Porus was a famous Indian king, his real name was #Purushotama. He belonged to PURU tribe mentioned in #RIG_VEDA, the Ancient books of India.


2) Porus ruled the Punjab region and expanded his kingdom between the Jhelum River and Chenab River in the Indian Subcontinent. He was a legendary warrior and more war skills. He made the army most powerful with war skills. Even Alexander had also made difficulty to defeat Porus.

3)Word of Mouth Oral tradition in #Mohyal_Brahmin families since ancient times has kept the Great Saga of their Great Elder known to them as Maharaja “ #Puru” alive.

4) When #Alexander the Great invaded India in 326 BC he was challenged near Taxila by a mere chieftain of the Area. He was King #Porus, a #Vaid_Mohyal. After his encounter with Porus, Alexander met with more resistance near Multan where the forces were predominantly #Mohyal.

5)The Bali rulers of Multan fiercely engaged with Alexander's army in skirmishes in which many senior Generals died. Later during the long and bitter fighting in #Multan, Alexander got hurt by an arrow which pierced his chest ,

“Don’t leave the church because of the people who hurt you. Nobody is perfect, only God”

I’ll explain why this comment is not only not helpful at all, but also very harmful.

1/

The comment assumes we can’t tell the difference between people and toxic theology, it assumes our issues are with a few people who are outliers and misrepresented God, and we just seem to think that’s the totality of divinity. Which makes us appear unintelligent and petty.

2/

But, that’s not the case at all. I didn’t leave because a few people hurt me in the name of God, in fact I stayed long enough to get hurt again, and again, and again, and again. Because it’s not a few bad apples hurting people in the name of God what we are dealing with.

3/

Instead we are talking about systemic abuse due to toxic theology that is taught as righteousness.

Go to any white evangelical church today and conduct all the tests you must to ensure only those who are “good Christians,” remain. I guarantee you people will be harmed there.
4/

Not because people just hurt people, not because Christians have good intentions but sometimes make mistakes; instead because the harm is caused due to indoctrination into toxic theology and a belief that their social and theological framework is not only good,

Chennimalai Murugan Kovil
#Erode
#TamilNaduTemples 🚩

Chennimalai Murugan Temple is located  near Perunthurai in Erode District. Murugan is worshipped here as Dandayudapani. Temple is situated on the banks of Noyyal river also called Kanchima Nadhi. Temple is situated in a hill


Sthala Puranam says that, there lived a Landlord who had many cows in his farm. One among them was a Black Cow, which didn't give milk. Land lord observed that evening time, when all the cows came back after grazing, this cow used to go to a particular spot and gave all  the milk


by itself. He decided to dig the spot where the cow gave its milk

On digging a beautiful Vigraham of Murugan was found, but lower portion was very rough. So he called a great sculptor to soften it. Everyone was shocked to see that on the first chisel the vigraham bleeded.


Land lord realized that Murugan wanted the Vigraham the way it was.

Thus Prathishta was done on Chennimalai hill. It is believed that Sivalaya Chola got relieved from his Brahmahatti Dosha here. Kanda Shasti Kavacham was first offered here.

👨‍💻 Last resume I sent to a startup one year ago, sharing with you to get ideas:

- Forget what you don't have, make your strength bold
- Pick one work experience and explain what you did in detail w/ bullet points
- Write it towards the role you apply
- Give social proof

/thread


"But I got no work experience..."

Make a open source lib, make a small side project for yourself, do freelance work, ask friends to work with them, no friends? Find friends on Github, and Twitter.

Bonus points:

- Show you care about the company: I used the company's brand font and gradient for in the resume for my name and "Thank You" note.
- Don't list 15 things and libraries you worked with, pick the most related ones to the role you're applying.
-🙅‍♂️"copy cover letter"

"I got no firends, no work"

One practical way is to reach out to conferences and offer to make their website for free. But make sure to do it good. You'll get:

- a project for portfolio
- new friends
- work experience
- learnt new stuff
- new thing for Twitter bio

If you don't even have the skills yet, why not try your chance for @LambdaSchool? No? @freeCodeCamp. Still not? Pick something from here and learn https://t.co/7NPS1zbLTi
You'll feel very overwhelmed, no escape, just acknowledge it and keep pushing.
