What is information quality decision making?

Information quality decision making is a concept in personal epistemology: Every decision you make is only as good as the information it is based on.

Example: You are deciding whether to leave your job and start a business. You have a gut feeling it is the right move. You have read a few success stories. A friend who runs a company says 'go for it.' But you have not researched your target market's size. You have not calculated your runway. You have not talked to people who tried and failed in the same space. You have not examined the base rate of success for first-time founders in your industry. You make the leap based on enthusiasm and selective data. Fourteen months later, you are out of money and back on the job market — not because the idea was bad, but because the information you used to make the decision was incomplete, biased, and unverified. The decision felt right. The information underneath it was wrong.

This concept is part of Phase 43 (Information Processing) in the How to Think curriculum, which builds the epistemic infrastructure for information processing.
