Nassim Taleb made his money trading markets.


Yes, I am aware of that

In the Black Swan he talks about his endeavor with the stock market and how lucky he got by chance, and not by using some pseudo scientific formulas and whatnot to "predict" how his stocks would do. He also gave some pretty good advice when it comes to the stock market

The whole book is just awesome, I'd recommend giving it a read


I have read it.

- He isn't a stock trader, he is a bond trader. The kind of bets you need to make to be succesful are different.

- "how lucky he got by chance" - He doesn't say this. He talks about how we can even better model uncertainties.


My apologies, you are correct on the first point.

>He talks about how we can even better model uncertainties.

Where does he say this? What chapter? Thanks in advance.

edit: were you alluding to his barbel strategy?


This data set should be expanded to include 100 of his peers who started trading at the same time.


Are there 100 people who know finance and think carefully like Nassim taleb? What do their outcomes look like? I would bet all of them do pretty well. (I'm not even a big Taleb fan.)

This is just like the startup founder argument. Every one which succeeds ends up having a tremendously interesting background demonstrating unique interest and capability.


Why do you feel so convinced they can't?


1. Their reasoning is arbitrary. They pick and choose factors to justify their analysis.

2. They would be much richer if they could.


because you can't know the future


Every scientific endeavor is about predicting the future. Imagine your 3 closest friends wanted you to invest in your business. Could you predict which of them would likely do better than the others?


Trading isn't about knowing the future. It's about having a positive expected value.


Politically connected people can shape the future. Nancy Pelosi's stockpicking skills are legendary.


Not even close to being a single-party problem. I know it's almost Halloween but you can do better than jumping out from around the corner yelling "Nancy Pelosi!"

Buffett says this kind of stuff publicly. But his own fund moves in and out of investments all the time.


He also said

>But it's true. I could name half a dozen people that I think can compound $1 million at 50% per year -- at least they'd have that return expectation -- if they needed it. They'd have to give that $1 million their full attention. But they couldn't compound $100 million or $1 billion at anything remotely like that rate.

A lot depends on the details of who's doing what.


Yep, you also wouldn't give the same computer/software advice to your grandma as you would a peer at work. Buffet is telling us to leave trading to the pros, but he absolutely trades.


Buffet is arguably the best who’s ever done it. He can do things your layperson shouldn’t try. Just because Bruce Lee could do an impressive spin kick, it doesn’t make spin kicks a good idea for 99% of people to try in a self defense situation.


I completely agree. This is true of most fields, which is why you can pay a professional for their special skills.


Sort of, not really? Most of BRK is invested in 100% wholly owned companies. They do have a "small"[0] public equity portfolio, that does change investments periodically, but most of those investments are also pretty long term, if you go look.

Wholly owned companies list: https://berkshirehathaway.com/subs/sublinks.html

0: In terms of BRK's overall wealth, it's still in the many billions of dollars.


The price system is how our society allocates resources. The fact that people are allocating their own resources to buy one -- without any perverse incentives or being compelled, indicates it's not wasteful to them.

A better example of waste is when local governments funds things which people don't use.

I think the root of this sentiment is misunderstanding or lack of satisfaction at the system level.


> And so we get this waste.

Wait. If they are making phones that get bought up every year because of people like your friend, then where is the waste?


In the landfill


Do you have any information about how much material going to landfills? What if 1 car is 1000 phones?


These things are always cyclical, but FOMO is a tough emotion to combat.


Let's hope being stuck at home for a year is not a cyclical event! That's what drove a lot of it, not FOMO. Building a home office, using a kitchen multiple times a day, schooling from home...


That doesn't drive people to pay 3x. What does it is the fear that prices will never come down or that this is a normal.


Having worked in the areas you are describing, it's still duct tape and rubber bands, they just are better prepared for redundancy and error recovery.


> they doubled down because they lack any sense of morality.

I don't believe you know what their internal mental states are.


We can and do reasonably infer mental states from actions.

If someone knows they are sending innocent people to prison, benefits from doing so, and continues doing so we can reasonably infer they lack morality.


Most internal mental states that have any impact on the actions of an individual are leaky. That is because they affect actual real world actions.

So given a set of actions you can infer a likely set of mental states — this is also done in the court room. Can you always infer with 100% accuracy and with every colorful detail fleshed out? No. Do you typically need to? No.


> this is also done in the court room.

And we have we gone through that process to look at the issue from all sides and hear arguments from all parties? No.

You don't need to know intent to fire or punish someone anyway. In this case we can dismiss people for improper action, without demeaning them personally.


If you read my post again you will notice I didn't say anything about the situation at hand. I just refuted your general statement that one cannot reason about mental states from the visible actions.

I agree that one should be cautious with early accusations or hopping on trains just because they are rolling.


And if you read what I said, before your comment, you'll see its about this particular situation.


Yeah, but my comment doesn't has to be. I am allowed to go into your direction, generalize your statement or put it into a different environment and examine it. How else should people discuss things?


Family relationships are much closer and have more trust than relationship between employer and employee.


So if a husband doesn't trust the wife, it is okay to have them clock in and out of the house and wear a tracker?


Maybe? Not my cup of tea, but if I didn't trust my wife, and she allowed me to track her, maybe that'd solve whatever hypothetical problem we were having. Very unlikely, but I don't think the idea itself, doomed to fail or not, is a problem if both parties consent.

Which is what you do when you work for an employer that wants to track your entries/exits into their buildings. You consent to allowing systems to be put in place that serve as placeholders for when trust isn't yet or won't be established.


What are you talking about?


This is only true if:

1. There aren't other processes that need to share the system.

2. There are no spikes in memory usage.

Neither are true. The less memory each component uses the more you can run at once and it will likely be faster too.
