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.)

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.

So, today, for the first time in 25 (!) years of Apple, I downgraded. From the 2016 MacBook Pro to my 2013, which I had kept in a drawer...


It was pretty simple to do—Apple Time Machine backups let me do it with one click.

That first tweet captures, in two pictures, how badly Apple has “lost the plot” (to quote @wylieprof). On the right is the Apple MagSafe adapter, from 2013. On the left, what I had “upgraded” to.

Thanks, Apple! I really was nostalgic for worrying about yanking my computer off the table.

Oh and I really appreciated not knowing if my computer was charging. What was great was the little whoop sound you used, so that the speaker before me could be informed I was charging my laptop.

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?

So—probability. Do we really need it? This has been on my mind since 2017, when I finally sat down to think through quantum theory. (/n)

One thing that’s always struck me is how *late* probability theory came in intellectual history. We had integral calculus before we had probability. And probability is insanely simple, mathematically!

I’m tempted to say that probability theory is not, in fact, Lindy. Frequentist probability is (for all the usual reasons) best understood as a heuristic. Bayesian interpretations, by contrast, take the remarkable step of tying it to mental states.

You have to work very hard to convince yourself that beliefs really are “degrees of belief in sets of events” (or whatever). It’s not natural—and I won’t rehearse the whole story about rational choice and decision theory...

So with those critiques in the back of my mind, when I read David Wallace’s decision-theoretic account of the Born Rule I was rather primed to say, hey, so what? Meaning...

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?

1/

So what actually moves the prices of cryptocurrencies? We spent over a month parsing through data to answer that question for you 👀👀

Special thanks to @eToroUS for partnering with us on this research

A thread:

2/

Leveraging The TIE’s Crypto SigDev™ feed we set out to identify whether news moved the crypto market and what, if any, impact sentiment had following key announcements.

SigDevs are news on token updates or major events (like M&A and Listings).

3/

Looking at ​maximum price increases within 24 hours after different SigDev announcements, we see that certain announcements tend to procure more responses than others. These are ordered from left to right in order of increasing average positive effect on price.


4/

These initial results are intuitive: one would expect 51% attacks — a negative assault on a blockchain — to not typically have a positive effect on price, while getting listed on a new exchange (“L​isting​”) increases demand for a cryptocurrency and thus should increase value

5/

Although Listings and Partnerships have an immediate large influence on price, it does not mean the increase is sustained.

We looked at how sustainable each SigDev was. Specifically, the max price 24 hours after each SigDev compared to the following week's average price

1/ Fear and Bitcoin.

Whenever Bitcoin has a bull run, naysayers try to cope with missing the boat by rationalizing why it will fail through “Fear, Uncertainty, and Doubt” or what we Bitcoiners have nicknamed “FUD.”

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

1/ crypto VC is going through an explosive 🧨 phase

there are big funds (>$500M AUM), a lot of small funds (<$50M AUM), and *tons* of prop firms + angels

i’ve done 15 deals in the last 3 months as an angel + small fund @CoinSharesCo VC.

observations + implications... 👇🏾

2/ the big firms need to deploy in size - $5M checks and up

a $250M fund could do a $5-10M deal every month for two years and still be under-allocated

and there aren’t enough companies raising series B / C / D rounds!!!

every deal i’ve done lately is under $50M valuation

3/ so we see firms competing to take down entire rounds.

a recent series A financing had two firms competing to take down the ENTIRE ROUND, and it eventually got upsized, a LOT.

if a company is putting up user acquisition / growth and a revenue story, it’s highly competitive

4/ most projects and co’s don’t need money tho - why would a founder take 20-40% dilution when they’re banking cash and crypto? so they do 5-10%

so the valuations go up, but available allocations go down, resulting in an even bigger squeeze on allocators who *need* to deploy

5/ add in the onslaught of non-crypto M&A that’s coming, which is culling the herd of investable unicorns

add in the wave of SPACs and direct listings taking later stage opportunities out

there just aren’t enough places to put capital in size rn

what’s a fund to do?

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) OBSERVATION: The frequencies are changing. I would have to assess stats on the electromagnetic field to see its fluctuations. All I know is, I am highly sensitive to energy/frequencies, and they are changing, because…

2) 2 Weeks ago, my dog was effected by it as well. He is hearing things that aren’t technically audible. I can tell by his body language and sounds. One week ago I began feeling a pressure in my head and ears. It wasn’t painful at all, but it was intense for a bit.

3) It reminded me of taking off in an airplane a bit. I felt like I was in a vacuum. It went on and off for a couple of days. I’ve picked up on frequencies and high pitched sounds (not audible to most) for 30 years, and today my right ear began to ring for longer than usual.

4) This is nothing unusual for me, with exception of the duration. This happens often with me. No, it’s not tinnitus. Only this time, when I spoke, there was reverb creating a high pitch in my ear from my voice. This lasted for about 30 minutes. It did not hurt, just annoying.

5) So yes, the frequencies are changing. What this means exactly, I am unsure of at the moment. Some will say electromagnetic fields, others will say ascension, and some will say pole shift. I honestly can’t say at this very moment.

I have to make a note before writing about this episode. I was the person (still am) who thinks that bringing back D. was a bad idea. I repeat it that for me the writing of S1 and S2 is like tossed into the bin with that plot evolution, but they had to invent something+

So, my comments are going to be how I find they wrote her into the story, the details we get to know, the flashbacks we get to see, the way it was filmed and directed, with leaving out if I agree on it or not but describing along the way what I saw.

1/ The first 18 months of starting a company is often life or death. I must've made 5 different companies that each failed within 9 mo. 😭 Each time the company failed I figured out what I could do better. Eventually startup #6 got to $40K/mo by month 18. Here’s what I learned...

2/ Stay focused! Ignore things that are a waste of time: meetups & conferences, meetings with no clear agenda, fundraising if you're not fundraising, reading lots of tech media articles, etc. Every week should feel like significant progress in the first year.

3/ Your first 5 hires will be the difference between life or death. Choose carefully. Be picky. Many of the things we do at the company still are a result of those early hires' legacy. Have fun as a tight knit team. It will change & evolve as you get bigger so enjoy this moment.

4/ Growth may be flat for the first 9 months. It's gonna be okay. Almost every company has experienced this: Airbnb had to sell cereal in-between, Slack failed as a gaming company first, Tesla sold only 147 cars after 6 years! You probably won't be an overnight success either.

5/ In the beginning, do customer support yourself. You will learn a lot about why your product sucks. I did 5,000+ support tickets when it was the two of us. Delight customers & fix things fast while you learn. It will help you build an amazing intuition about your customers.
