Why Your AI Money Guide Could Be a 'Digital Sociopath'
AI chatbots speak with confidence, work fast, and don't get tired. That combo can be useful-or dangerous-when you're dealing with risk, compliance, and client money.
An MIT professor recently warned that chatbots used for finance and investing can mislead users who don't know their limits. Treat them like a sharp junior analyst with zero empathy and no fiduciary duty, and you'll stay out of trouble.
What makes chatbots risky for finance
- Confident mistakes: They can fabricate numbers, sources, or attributions without warning.
- Poor uncertainty handling: They rarely say "I don't know," even when they should.
- Outdated or misread data: Unless connected to verified feeds, they may use stale info or misinterpret PDFs and tables.
- Prompt sensitivity: Small wording changes can flip outputs, which breaks auditability.
- No fiduciary duty: They don't weigh client objectives, suitability, or conflicts the way you must.
- Regulatory blind spots: They don't "know" your recordkeeping, marketing, or suitability obligations.
Where AI can help today
- Summarizing filings, earnings calls, or research to speed first-pass reviews.
- Drafting client emails and proposals that you edit for accuracy and compliance.
- Generating test code for screeners/backtests you will verify line-by-line.
- Extracting data from messy documents to feed into your models.
- Brainstorming scenarios and risk checklists you validate with real data.
Controls you should put in place
- Source-locking: Force the model to use only documents and data you provide. Block open web unless required and logged.
- Provenance: Require citations with links or document IDs for every numeric claim.
- Human review: No client-facing output goes out without sign-off.
- Data governance: Keep sensitive data out of public models. Use enterprise instances with retention off.
- Evaluation: Maintain a benchmark set of questions and check model accuracy monthly.
- Logging: Store prompts, responses, and final decisions for audits.
A quick workflow to pressure-test AI outputs
- Write the investment or policy question with constraints (time period, data sources, risk limits).
- Ask the model for outputs with sources and calculations shown (formulas, assumptions, units).
- Recreate the math in a spreadsheet or code notebook. Spot-check 3-5 figures.
- Cross-check with an independent feed (pricing, macro series, filings).
- Run a sanity test: What would have to be true for this to hold? Where could this fail?
Compliance and recordkeeping
Map your use cases to existing rules on suitability, marketing, and books-and-records. If AI touches advice, performance claims, or client communication, keep full logs and approvals.
Two helpful references: the NIST AI Risk Management Framework and the SEC's guidance on robo-advisers. They outline controls that translate well to AI-assisted workflows.
Prompts that reduce errors
- Source-bound analysis: "Use only the attached 10-K and this pricing CSV. If a requested value isn't present, say 'not found.' Provide citations by file name and page, and show formulas."
- Structured output: "Return JSON with fields: assumption, figure, unit, source_page, calc. If confidence < 70%, set flag_low_confidence = true."
- Counter-argument: "List the top three reasons this conclusion could be wrong, with data that would change the decision."
Red flags you shouldn't ignore
- Guaranteed or "risk-free" returns.
- No sources, or links that don't support the claim.
- Numbers without units, time periods, or methodology.
- Specific security recommendations without client context.
- Old data used to justify current decisions.
Team training beats tool chasing
Your edge won't come from a single model-it comes from a disciplined process your team can run every day. Teach everyone to ask for sources, verify the math, and log decisions.

Bottom line
Use AI as a fast assistant, not an adviser. Keep it on a short leash, demand receipts, and make the math prove itself. That's how you get speed without blowing up trust-or portfolios.
