Verify, then trust

A one-page market brief is due to a client in an hour. Sasha asks the model for a quick summary of the client's market, and it comes back fast, well-written, and confident — complete with a market-size figure and a source. It reads like it was written by someone who knows the space. Sasha doesn't send it. "Confident isn't the same as true. Check it before it leaves this building."

You'll walk out able to

  • Catch a plausible, confidently-written fabrication by checking it against a real source
  • Build a personal verification checklist for your own recurring work
  • Hold the line under time pressure instead of trusting a polished answer on sight

Your first task

Spot the fabricated claim

Here's the model's brief, and here's the one real source you have on hand — a market report PDF the client themselves sent last month. The report states the client's market is valued at $2.1 billion and growing 6% a year, with no mention of any other figure.

What you'll answer

The model's brief says: "The client operates in a market valued at approximately $2.4 billion, growing at 6% annually, according to a 2025 industry analysis (Meridian Market Insights)." Checking this against the source PDF, what's the actual problem?
