Module 03 teaches one of the most important distinctions in the course: useful language is not the same as verified information. The reader learns when to stay in chat, when to invoke Search, how to read citations, how to ask for stronger evidence, and how to turn source-backed work into a brief that can withstand scrutiny.
Module summary
This module is less about skepticism for its own sake and more about intellectual hygiene. It helps the reader move from plausible answers to supported answers, especially when facts are current, contested, or consequential.
The lessons build a simple professional habit: choose the right evidence mode, inspect support instead of admiring it, raise the quality bar when needed, label uncertainty honestly, and package the result in a way another person could actually trust.
Lessons in this module
when-to-use-chat-vs-search- Choose the right evidence mode before you phrase the question.reading-citations-and-sources- Use citations as an evidence trail, not a decorative trust signal.asking-for-stronger-sources- Raise source quality by asking for better evidence classes rather than more URLs.cross-checking-and-uncertainty- Use uncertainty labeling to improve honesty and decision quality at the same time.building-a-source-backed-brief- Turn verified claims into a brief that other people can read, trust, and use.
How to use this module
Read these lessons before relying on ChatGPT for research-heavy or decision-heavy work. The source-backed brief lesson is especially useful if you write memos, recommendations, or summaries for other people.
This module also changes how you read the rest of the course. Once you understand the difference between a fluent answer and a supported answer, features like Search and Deep Research stop looking like novelty and start looking like evidence tools with different jobs.
