Sorry, about the rant: ELI5 really triggers me. Have you ever talked to a five-year-old? They're very interested but ignorant and have minute attention spans.

Sorry, about the rant: ELI5 really triggers me. Have you ever talked to a five-year-old? They're very interested but ignorant and have minute attention spans. Have some self-respect, put on your big boy pants and at least make an effort to understand the adult version and ask some specifics about what you don't understand. What you're asking for is a full on Malcom Gladwell style essay. Not only that, but all the points are discussed in the linked blog post. If one can't even be asked to put in the effort to read it, isn't it a bit presumptuous to expect anyone to summarize for you in elaborate detail!? ELI5 would be: The authors wanted to find out if housing prices have something to do with bad air. They thought some people unfairly make homes cheaper if black people live in them. And that in some cases more expensive. Instead of including data about how many black people live in a neighborhood he included a value that supports his opinion and can't be checked. Because scientists aren't supposed to base their conclusions on gut feelings, this makes the sample data an example for problems that arise when working with data. Five year olds are not particularly intellectual and wouldn't enjoy the discussion of biased models with feature-invertible data!
