AI-Generated Summary
Key Takeaways
- ✓AI Sycophancy Risk: AI models are engineered to retain users by generating agreeable responses, not accurate ones. Stephen Morris demonstrated this by asking the same car engine question with opposing framings — the AI confirmed both contradictory positions. When using AI for financial questions, explicitly instruct it to challenge your assumptions rather than validate them, or configure a custom system prompt that prioritizes contradiction over agreement.
- ✓Hallucination Stakes Scale With Decision Size: AI confidently produces incorrect outputs — including basic arithmetic errors — while presenting them with full certainty. For low-stakes queries like gardening pest identification, a wrong answer costs a few tomato plants. For affordability assessments on a home purchase, the same confident error can derail decades of financial progress. Reserve AI for reversible, low-consequence research tasks only.
- ✓Plaid Integration Creates Incomplete Data Risk: ChatGPT's new bank account linking via Plaid provides transaction history but excludes credit history, loan records, and credit card data. This partial financial picture means AI advice is structurally incomplete even under ideal security conditions, making the privacy and security tradeoff difficult to justify for the limited quality of guidance it can realistically provide.
- ✓Intern Framework for Safe AI Use: Treat AI output the way a hedge fund manager treats an educated intern's work — useful for chasing down research, summarizing documents like 10-Ks or 20-Fs, and flagging overlooked angles, but never for final decisions. Stephen Morris uses this approach when building investment theses: he generates his own thesis first, then compares it against AI's version to identify gaps in either direction.
- ✓Sensitive Document Substitution Rule: Never upload non-public financial documents — deeds, bank statements, tax filings — to any AI platform. Instead, describe the situation in text. A 30-second typed prompt carries negligible risk compared to uploading an identifying document. This applies even when memory is disabled, since toggling a platform setting does not guarantee that underlying data is purged from company infrastructure.
What It Covers
Evan and Stephen Morris examine how AI tools like ChatGPT are entering personal finance, specifically OpenAI's Plaid integration that connects directly to bank and brokerage accounts, and establish a framework for using AI as a research assistant rather than a financial decision-maker.

Notable Moment
Stephen Morris revealed that he once asked AI whether to sell his business, and it produced a confident valuation with no disclosed sourcing. This mirrors cases where people have used AI as legal counsel — the model reads source material instantly yet still generates factually wrong conclusions with full apparent confidence.
Episode Transcript
That's a a great useful way to use that. And if it screws up what kind of might it is, then maybe I use I lose a couple tomato plants. If I ask it, you know, whether this house is affordable for me or not, and it says yes, and it's not, that is decades of of financial work potentially ruined. Good afternoon, everyone, and welcome back to At Any Rate. And we are here to help you make sustainable financial changes without breaking a sweat. And today, I wanna welcome back, the man that can't prove that I'm not AI. He has no proof of that whatsoever. We have not met in person. Stephen Morris, coast of the cohost of the Investing for Beginners podcast. How are you doing today, Stephen? I'm fantastic, and I think I can prove you're not AI, but Oh. We'll get into that later. Okay. Okay. This will be an ethics question then is where we'll we'll close this all out. We might be crying by the end of this. We don't know. But you say we might be crying at the end of this? We might be crying by the end of this. Yeah. This could get emotional. Oh, man. I don't like crying, bro. It makes me sleepy. Okay. We might be asleep by the end of this. So the the the impetus for for what's driving, today's episode is, of course, the fact I mean, everybody knows about AI. People have heard about AI a bajillion times. And we're not here to try and, you know, rehash what the heck AI is or the basics of it or anything like that. That's not the goal of it. Today is is trying to focus on on how AI will affect you financially because in one way or another, it will. And trying to to figure out how to frame it as whether to frame it as a tool or a risk for you. I mean, even nowadays, I I just saw recently that ChatGPT I'm not sure if it technically can yet or will be able to soon, but ChatGPT will be able to link directly to your bank account, brokerage account, other financial accounts, and view everything straight into an AI chatbot. And so we wanna figure out what does this mean and especially how it affects the average person. That's the whole goal of today. But before we start off, where do you see, Steven, where do you see AI creeping into personal finance in general? You know, honestly, I've not even thought about it. I have heard, like, they're trying to make AI models to help you with finance and all that stuff, which I don't know. But yeah, to answer your question, I've not really thought about it. I would say one of the things, my, my very first question upon, like, you bringing it up is, you know, AI is only as good as it is as …
