What is reactive emotions?

Reactive emotions is a concept in personal epistemology: Strong emotional responses to information often indicate manipulation, not importance. Your triggers are not a relevance filter — they are a vulnerability map.

Example: A product manager reads an industry blog post predicting that their company's core technology will be obsolete within two years. She feels a surge of anxiety and anger. Her first instinct is to share it in Slack with an alarmed commentary, forward it to her VP, and start drafting a pivot plan. She pauses. She has felt this exact pattern before — three times in the past year, each time about a different prediction, none of which materialized. The emotional intensity is not proportional to the article's evidence. It is proportional to her fear of being caught unprepared. The information in the article may or may not be signal. But the emotional urgency she feels is noise — it reflects her anxiety trigger, not the article's analytical rigor. She logs the article for a calm review on Friday, when she can evaluate the evidence without the activation.

This concept is part of Phase 7 (Signal vs Noise) in the How to Think curriculum, which builds the epistemic infrastructure for signal vs noise.
