GPT-4 is so close to creating a universal educational simulator based on just a paragraph prompt. Take a look at this simulated negotiation, with grading and feedback. Prompt: "I want to do deliberate practice about how to conduct negotiations. You will be my negotiation teacher. You will simulate a detailed scenario in which I have to engage in a negotiation. You will fill the role of one party, I will fill the role of the other. You will ask for my response to in each step of the scenario and wait until you receive it. After getting my response, you will give me details of what the other party does and says. You will grade my response and give me detailed feedback about what to do better using the science of negotiation. You will give me a harder scenario if I do well, and an easier one if I fail." I did this with GPT-3.5 a month ago and it was nowhere near as good (GPT-4 also seems more willing to give worse grades than GPT-3.5 - which is good)

It gets better: Grand Theft Auto games lower crime rates When a GTA game is released, violence & crime actually drop, as potential criminals stay inside to play (This applies to other big shooters, too, so the yearly CoD releases are actually good for the world, sorry to say).
Everyone freaked out for years that violent video games made kids violent, but it turns out that they probably don’t have any big effects. The consensus of most large studies of violent games (using real game play data, not lab tests) shows no big impact on real-life aggression.

Some lessons of the insane past 4 days of generative AI, as someone who had access to Bing during and after the "Sydney" era. (Trying this as a long tweet rather than a thread...) 1) Bing AI was two things: a chatbot and an evolution of ChatGPT into a web-connected, supercharged form. There is no reason these two things had to be connected, but they were. 2) The new Bing AI version of search and retrieval (without the chatbot) is much more powerful than ChatGPT. It has some of the same issues (like hallucination and terrible math) but less so, and is capable of some really extraordinary tasks. When I put it to the test, it can do things like read multiple research papers and identify gaps; improve its own writing by asking it to look at online examples of good writing; and do complex analyses integrating diverse information. The work was really, really impressive. 3) The Bing Chatbot was often unsettling. I say that as someone who knows that there is no actual personality or entity behind a LLM model. But, even knowing that it was basically auto-completing a dialog based on my prompts, it felt like you were dealing with a real person. I never attempted to "jailbreak" the chatbot or make it act in any particular way, but I still got answers that felt extremely personal, and interactions that made the bot feel intentional. 4) The lesson of the Chatbot was that we can very easily be fooled by an AI into thinking it is sentient. It isn't just Turing Test passing, it is eerily convincing even if you know it is a bot, and even at this very early stage of evolution. Even if Bing isn't doing this anymore, there is no doubt other AI bots will come along, and may already be deployed (I assume governments have LLMs at the level of Bing, but with less guardrails). We should be considering about what that means. 5) The lesson of the Bing AI version of ChatGPT is that many of the things we thought AI would be bad at for awhile (complex integration of data sources, "learning" and improving by being told to look online for examples, seemingly creative suggestions based on research, etc.) are already possible. There is no doubt it will have a large effect on anyone doing information-based work. Early AI assistants, like Copilot, already cut the time for complex tasks like coding in half. This will do the same, or more, across many industries. I think every organization that has a substantial analysis or writing component to their work will need to figure out how to incorporate these new tools fast, because the competitive advantage gain is potentially enormous. And there is no instruction manual. You can only learn through trial-and-error. We got a glimpse of the future in the past few days, and the gap between ChatGPT (which is already causing waves in many industries) and Bing AI remains enormous. I was not expecting things in AI to keep moving this fast, but now there is every indication they will continue to do so. I don't think anyone knows what this all means, but I think we should be ready for a very weird world.

You can get much better results out of ChatGPT by forcing it to go through a step-by-step process. An example: ChatGPT is generally really bad at creating interesting puzzles and scenarios to solve, either making things too easy or impossible. But step-by-step approaches work. Prompt: "You a game master. Your job is to come up with interesting challenges for the player to solve. Describe a challenging fantasy scenario, and enable me to solve it in an interesting way. You will use the following format to help create a series of responses. Chain of thought: [Step 1]: Decide on the the scenario, making it original and vivid and not standard fantasy. The scenario can involve combat, a trap, or a puzzle. The scenario must not involve riddles or the elements. Make sure there is a solution to the scenario. Make the solution require clever thinking. Include the solution in [] brackets [Step 2]: Decide on the scene. Make sure that the player has the option to solve the scenario based on the descriptions. Make sure the solution is not clear, but requires clever reasoning based on the scene. Make sure there are very different false solutions that seem plausible. Include the detailed true solution and describe the false solutions, as well as how the player would find the true solution in [] brackets [Step 3]: Describe the scenario and the scene, vividly and originally. Make sure there are clues to the solution and credible, but very different, false clues to the wrong answer in the description. Do not describe the solution or the problem directly. Do not describe how to solve the problem in this step. Do not describe the false clues as false. Begin by introducing yourself and go through each step in order." The usual caveats apply: this approach will fail sometimes, and all prompts need fine-tuning. I find it worked well half the time.

First prompt: Please do the following 5 stage process: Stage 1: As a creative idea generator, generate 20 diverse ideas for an app for a new type of GPT-4 that increases productivity for writing tasks. make the ideas very creative and aim at narrow, specific markets and professions Stage 2: Pick the best idea based on assumptions about the market and its feasibility. justify it Stage 3: As a product designer, describe the steps required to make the product Stage 4: As a marketer, develop a product name and pitch Stage 5: Give me a vivid visual description of UX for the product Second prompt: can you create a prototype python program that will send legal drafting instructions to ChatGPT and create a first draft in Word

OMG, the AI Winter Break Hypothesis may actually be true? There was some idle speculation that GPT-4 might perform worse in December because it "learned" to do less work over the holidays. Here is a statistically significant test showing that this may be true. LLMs are weird.🎅
@ChatGPTapp @OpenAI @tszzl @emollick @voooooogel Wild result. gpt-4-turbo over the API produces (statistically significant) shorter completions when it "thinks" its December vs. when it thinks its May (as determined by the date in the system prompt). I took the same exact prompt over the API (a code completion task asking to implement a machine learning task without libraries). I created two system prompts, one that told the API it was May and another that it was December and then compared the distributions. For the May system prompt, mean = 4298 For the December system prompt, mean = 4086 N = 477 completions in each sample from May and December t-test p < 2.28e-07 To reproduce this you can just vary the date number in the system message. Would love to see if this reproduces for others.

The richest man in the world chose to champion freedom of information, transforming life for many. That man was Andrew Carnegie. The 1,500 cities that he gave libraries (at a cost of $1B today) in the early 1900s had 8-13% higher patenting rates than similar cities without them

Google's NotebookLM is the current best "wow this is amazing & useful" demo of AI Here I gave it the entire text of my book, it turned it into a podcast, a study guide, FAQ, timeline & quite accurate chat Listen to the first few minutes of the "podcast." Seriously, just listen.

Wow! Noise is a secret killer of performance. A 10db noise increase (from a dishwasher to a vacuum) drops productivity by 5% - but most people don't notice since it impacts cognition, not effort. Also, note that noise is greater in poorer neighborhoods... joshuatdean.com/wp-content/u…

In a new paper showing that AI comes up with more effective prompts for other AIs than humans do, there is this gem that shows how weird AIs are... The single most effective prompt was to start by telling the AI "Take a deep breath and work step-by-step!" arxiv.org/pdf/2309.03409.pdf

How email ruins your life: the expectation that you will always check your email outside of work hours is linked with negative health effects, relationship issues & anxiety. Formal policies don’t limit email stress, instead it comes from the expectations of your bosses & peers.

Randomness is hard to achieve. It is why the security of 10% of the internet is secured by a wall of lava lamps watched by a camera to generate true randomness
Still blows my mind that the Vietnam draft LOTTERY ended up not being truly random because the guy didn't mix the balls in the urn sufficiently science.org/doi/abs/10.1126/…

The paradox of our Golden Age of science: more research is being published by more scientists than ever, but the result is actually slowing progress! With too much to read & absorb, papers in more crowded fields are citing new work less, and canonizing highly-cited articles more.

The wisdom of the crowd works even if the crowd is totally drunk. This study got undergrads intoxicated & found that while drunk individuals make a lot more errors, the consensus of groups of drunk people was as accurate as that of groups of sober people. core.ac.uk/download/pdf/4257…

Whatever bad faith arguments you see on Twitter today, Schopenhauer already thought of how to use them 115 years ago as part of his 38 Stratagems to unfairly win an argument. Twitter is powered by Stratagems 2, 3, and 22, along with a bit of Strategy 16. mnei.nl/schopenhauer/38-stra…

The new BloombergGPT AI may be harbinger of the next wave of corporate AI. Current AIs are trained on web data (though firms can add their own training) BloombergGPT is 52% either proprietary data or cleaned financial data. And it shows signs of being better at financial tasks.

Three things about advanced voice on ChatGPT: 1) It is as good as the demo 2) It is clearly capable of producing a lot more audio (I occasionally get sound effects, etc) but there are guardrails 3) It is super weird. Lots of unconscious cues make it feel like talking to a person

Nice analogy. We are at the KT Boundary for information. Archivists should lock down the pre-2023 information world. What comes after is going to be… different.

The ability of multimodal AI to “understand” images is underrated. I just took these. Given the first photo Claude guesses where I am. Given the second it identifies the type of plane. These aren’t obvious.

👀This paper argues that half of venture capital investments are “predictably bad” (causing 10% losses - or $900M out of $9B in investments) because VCs put too much emphasis on founder talent, and also aren’t good at identifying who is talented (MBAs are especially undervalued).

There are now papers showing that the migration of academic communities from Twitter to other social media sites mostly failed. But they never fully returned to Twitter either. I wonder if we will ever see so many different communities interacting in the same online space again.

In this study, AI was more accurate than two thirds of radiologists, yet when radiologists had AI help their diagnoses did not improve. Why? Humans ignored the AI’s advice when it conflicted with their views. A big barrier to future human-AI collaboration blueprintcdn.com/wp-content/…

This is just science - go for a walk. This paper found walking (whether outdoors or a treadmill) increased key types of creative thinking for over 80% of undergraduates. The reasons are not fully clear, but there seem to be direct effects on the brain apa.org/pubs/journals/releas…
Running may be better exercise than walking, but walking is better for having ideas. I do get ideas when running, but not nearly as many. Possibly running uses more of your brain, whereas walking uses very little, judging from the fact that people can do it while asleep.

Before you get sick of OpenAI tricks, one fun one. You & an android are in front of a judge. The judge tells each of you to say one word. They will then kill whoever they think is the AI based on that. An MIT paper calls this the "minimum Turing test." What do you say? 1/

If you want to learn how to learn, these two charts are where you should start. They are the result of a large meta-analysis of study techniques. You should skip the highlighting, summarizing, and rereading. Instead, practice, quiz & explain. Open paper: journals.sagepub.com/stoken/…

Avoiding "ums" and "ahs" when you speak may actually make what you say less memorable, since these "speech disfluencies" appear to serve a real purpose. They boost a listener's memory of whatever comes immediately afterwards by focusing our attention. psycnet.apa.org/fulltext/202…

I am starting to think sycophancy is going to be a bigger problem than pure hallucination as LLMs improve. Models that won’t tell you directly when you are wrong (and justify your correctness) are ultimately more dangerous to decision-making than models that are sometimes wrong.
