Frequently Asked Questions
The score ranges from 0% (not delusional) to 100% (extremely delusional). It is calculated based on high confidence combined with low evidence and low plausibility.
The formula is: (Confidence × (100 - Evidence) × (100 - Plausibility)) / 10000. This emphasizes that delusion increases with confidence despite lacking evidence and plausibility.
