Benchmarks and results
Analyze sentiment and quantitative text metrics
Compare human and model language using automatic VADER sentiment and transparent descriptive counts.
The basic idea
Automatic text features are reproducible descriptive outcomes. VADER compound and positive, neutral, and negative proportions characterize English lexical tone; word, sentence, and lexical-diversity measures characterize form. They do not by themselves measure factual accuracy, argument quality, intent, or a person's emotional state.
Compare the mean VADER compound score, word count, sentence length, and lexical diversity of human and model contributions across solo-AI, council, hybrid, and human-only conditions.
How to do it
- 1
Open a completed run or participant-study analysis to view automatic text measures by source and condition.
- 2
Use the version field and the same unit of analysis in every arm.
- 3
Export the metrics alongside transcripts or game moves, then prespecify whether inference is at the message, participant, item, session, or condition level.
- 4
Inspect distributions and clustered observations before testing condition differences.
What to watch for
- VADER is designed for English and may misread sarcasm, negation in specialist language, slang, and translated text.
- Longer responses can mechanically change counts and lexical diversity.
- Repeated turns from one participant or benchmark item are not independent observations.
What a useful result looks like
Every supported experiment format exposes versioned, zero-API-cost sentiment and text-form measures while retaining the underlying text for audit and alternative coding.
