Information Density — The Lens

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Info Density Power-words vs. Substance ratio.

Information density is exceptionally high. Instead of relying on generic power words, the headings are descriptive and noun-heavy, such as Artificial intelligence and Data science and analytics. The body text contains specific dates (founded in 1209 for Cambridge), specific numbers (enrollment of over 20,000 degree candidates at Harvard), and a functioning promo code NEXTMOVE2026 valid until May 19, 2026.

Information Density is read straight from the body copy: how much of the text carries grounded, checkable substance versus hollow filler. Below is the clean text the engine analyzed, then the industry’s known generic-claim patterns to weigh it against.
