Our intuitions often leads us astray. A good reminder: study counterintuitive math and economic results.

Here are 9 of them 🧵

The Birthday Paradox

In a room of 23 people, there's a >50% chance that 2 people share the same birthday.

This type of probabilistic thinking does *not* come naturally to many people.
The Coastline Paradox

Fractal geometry is also confounding:

The coastline of a landmass does not have a well-defined measurement. As the unit of measurement gets smaller (eg. from KMs to cm), the length increases without limit.
Winner's Curse

In an auction, the winning bid will usually exceed the intrinsic worth of an item leading to a significant overpay (and negative net profit for the winner).
Braess's Paradox

Removing an extra road can make everyone's commute time faster.

Why? The existence of a "fast" road leads to congestion because everyone uses it. If you remove the shortcut, traffic flows better.
Market for Lemons

If a seller has slightly more info than a buyer (eg used cars), it can lead to market failure:

◻️Buyer will pay price below market (b/c they can't confirm quality)
◻️High-quality sellers leave market b/c can't get good price
◻️Only low-quality sellers remain
The Potato Paradox

If you take 100lbs of potatoes which are 99% water by weight and you let it dry so that they are 98% water, their new weight is 50lbs.
The Pizza Paradox

One 18-inch pizza has more "pizza" than two 12-inch pizzas (still trying to process this fact).
Littlewood's Law of Miracles

An example of the law of large numbers: A person can expect to experience events with odds of one in a million at the rate of about once per month.

(Similarly: in a world with ~8B people, a one-in-billion event will happen 8x a month)
Queuing Paradox

If bank customers take on average 10 minutes to serve and they arrive randomly at a rate of 5.8 per hour...then the waiting time for

◻️one teller is *5 hours*
◻️two tellers is *3 minutes*

Waiting time is reduced by 93x by adding a second teller.

The Wall Street Bets due diligence on Wendy’s is gold.

The catalysts are:
◻️ The release of a new summer salad
◻️ The @Wendys Twitter account, which has mastered “meta pragmatic roasting” (which is effective with younger people)
◻️ The fact it literally sells chicken tendies


OP:

Here’s a more fundamentals-driven analysis of Wendy’s

More from Finance

1/18 After 3 months, @saffronfinance_ is no longer new on the scene. Now that the kid has climbed the ranks, it's time to see if he can hang with the big boys.

Below are some updated thoughts on potential integrations, improvements, and innovations for Saffron moving forward. ⬇️


2/18 First, if you haven't seen @Privatechad_'s alpha-leaking introductory thread, you should check it out.

I agree that @AlphaFinanceLab and @CreamdotFinance, specifically the Iron Bank, would be ideal targets for SFI risk tranches.


3/18 Speaking more broadly, Saffron is primarily integrated with @compoundfinance, which has served as a MVP of sorts.

The thing is, Compound is one of the safest (but also lowest yield) protocols in DeFi, so it's not surprising that there isn't much demand for the sen. tranche.


4/18 Expanding beyond Compound to higher-risk/higher-return protocols has always been key.

These protocols are the bread-and-butter target market for Saffron, and I would expect to see a surge in demand for senior tranche staking in these


5/18 Additionally, @DeFiGod1 convinced me that Senior Tranche pools would be more appealing if they offered fixed yield.

Essentially, Saffron would augment the product offerings of @Barn_Bridge by also offering senior stakers insurance in the form of junior tranche collateral.

“We don’t negotiate salaries” is a negotiation tactic.

Always. No, your company is not an exception.

A tactic I don’t appreciate at all because of how unfairly it penalizes low-leverage, junior employees, and those loyal enough not to question it, but that’s negotiation for you after all. Weaponized information asymmetry.

Listen to Aditya


And by the way, you should never be worried that an offer would be withdrawn if you politely negotiate.

I have seen this happen *extremely* rarely, mostly to women, and anyway is a giant red flag. It suggests you probably didn’t want to work there.

You wish there was no negotiating so it would all be more fair? I feel you, but it’s not happening.

Instead, negotiate hard, use your privilege, and then go and share numbers with your underrepresented and underpaid colleagues. […]
