What is the definition of Recommendation Research?

Recommendation research is like a detective trying to solve a mystery, but instead of murder suspects and missing clues, it's hunting down the most popular choices or products for people's consumption. It's all about predicting who will buy what, based on who's already bought it. Think of it as the ultimate social media algorithm, but instead of tweets and likes, it's your favorite Netflix show and the next big tech gadget.

Example sentence: "Based on your recommendation research, I'm sure you'll find this new brand of peanut butter to be the ultimate life hack, despite my personal belief that it's just a bunch of stale peanuts masquerading as something better."
