Let’s talk the science of demos!

Research has shown demos give "cognitive legitimacy:" making a product plausible & inevitable. This paper on Shark Tank shows the more prepared (coherent, fact-based, narrative) the pitch, the more legitimate it seems & the more $ it raises! 1/4 ImageImage
Good entrepreneurs (as well as scam artists 👇) use demos and prototypes as part of an overall push for legitimacy. They are an important symbol of success for companies 2/4
Demos work in established companies, with caveats. If you are trying to pitch a novel idea to your boss, they will think you more creative & persuasive if you do a simple (crude) demo. If the idea isn’t novel, showing prototypes makes your boss think you are LESS creative. 3/4 ImageImage
We end with a famously effective demos. Watch how Jobs builds legitimacy:
1) Tells a story about why Apple’s win was inevitable
2) Demo'ed & described, the (secretly barely working) product
3) Combined personal style with careful preparation 4/4

I don’t know if LLMs can reason in theory, but they seem to “reason” in practice.

Ask Claude a Fermi problem: How many telephone poles are there in Manhattan? (Guess: 440. Actual: 0). On Staten Island? (Guess 19000-2859. Actual: 27,137) Queens? (Guess: 51-85k. Actual: 103k)

It doesn’t seem to have the number handy, but, even if it did, next token prediction should mean it reasons forward, not backward from a conclusion.
They are obviously not good at all sorts of problems (logic puzzles, etc.) but they do well at many others (Fermi problems, etc).

Reasoning is a jagged frontier for LLMs.

Reminders about how to stay sane on Twitter:
1) You don't have to weigh in on anything you don't want to (or don't know anything about)
2) You should block more
3) You don't need to share your real life
4) Delete a lot of drafts
5) You can delete tweets people take the wrong way
6) Don't be a jerk. Think twice before quote-tweeting to dunk on people
7) Emotional contagion online has support in the academic literature. You don't need to keep the chain of bad feelings going
8) Twitter people do not represent real-life views, don't take it too seriously
9) Either be very trigger-happy to curate your For You page or stick to your Following page. Algorithms optimize for engagement. Things that make you mad engage you, and then you will be shown more things that make you mad
10) You cannot judge real-life consensus based on Twitter

Write me a corporate memo covering the following points, integrating them together in a good way:
-Forgive me for the murder I committed
-We will hit quarterly steel crumpet goals
-The fish people are here to evaluate our offer. Make sure to speak to them only in fish. Include some fish people sayings
-Do not touch the vortex in the break room. Explain why. -We have pivoted from a NFT company to an artisanal pickle shop. Give details about their similarities.
-Anyone not acknowledging Pluto is a planet will be fired. There will be a series of tests.Image
The legal and PR teams have asked you to walk everything back (even though everything that happened was real, and everyone knows its real), each point for a different reason, write that memo make the excuses elaborate and obviously transparent and over-the-top. Image
the floor is now lava, explain why, give new procedures, spin it positively. its actual lava. not fake, not a joke. lava.

(OMG, it has it in for Steve, hilariously, see the last memo) Image

So how is Runway AI able to model fluid dynamics reasonably well?

The prompt: "A highly detailed portrait of a marble eagle with honey oozing down. Cinematic, highly detailed, film grade."

It isn't perfect (the viscosity seems to change a bit, etc), but why does it work at all?
This is going to be one of those posts where the reactions are divided between "this isn't anywhere as good as you could get with a physics model of fluid over a surface" & people who say "wait, how does a text-to-image model have anything like consistent physics for new scenes"
That prompt: "overhead shot: Two pirate ships sailing back and forth in a cup of coffee in a storm. Cinematic, highly detailed, film grade."

Civilization VII was announced today.

The Civ series is sort of like Ender’s Game, but for management rather than murdering aliens. Business school students who were good at Civ V also turn out to be better planners, organizers, and problem-solvers, in this small experiment. Image
Other games work as effective tests of fluid intelligence:
⌨️Performance in MOBAs like League of Legends and Dota correlates with intelligence
🎮Performance in FPSs like Battlefield, Destiny, and (likely) Fortnite don't show the same pattern

This qualitative research paper argued that the the skills of a raid leader in World of Warcraft & MMOGs work for offline leadership skills as well. Good guild leaders make good real leaders.

Azeroth-based recruiting still hasn't taken off, though... google.com/url?sa=t&sourc…

AI detection in school is a losing game.

AI detectors have high flaw positives & teacher intuition seems to work even worse: “Here we show in two experimental studies that novice and experienced teachers could not identify texts generated by ChatGPT among student-written texts.” Image
“High false positives”
