Burstiness

See also: AI text, AI content and AI content detectors

Burstiness or text burstiness refers to the pattern of sentence length in written text. Humans tend to write in a bursty fashion with short and long sentences interspersed, while machines tend to write uniformly with mostly sentences of the same length. GPTZero primarily detects this difference. To measure text burstiness, one looks at the probability distribution of sentence length. A neat, uniform probability distribution indicates a computer-generated text, while a messy, inconsistent distribution suggests human writing.

Writing content with high burstiness, along with high perplexity, is the main method to avoid being flagged as AI generated content by AI content detectors like Originality.AI and GPTZero. See the full guide here: How to write articles to be undetectable by AI content detectors
