      if your Big Data person does NOT know what this picture means, get rid of thempic.twitter.com/0yVHZzcYoz

      the famous "survivorship bias" diagram of an idealized PV-1 bomber viewed from the top with red dots around the tail, center fuselage, wing roots behind the engines, and outer edge wing tips.

The US military wanted to use data from returning damaged bombers, the red dots signified damage they recorded, to determine what parts of the plane to uparmor. Statistician  Abraham Wald realized that they were ONLY able to analyze the planes that RETURNED. 

Therefore the damage they were recording was ONLY that which could be sustained and allow the crew to safely return. The planes that had sustained fatal damage, the ones that really needed armor, didn't make it back to be recorded by the statisticians

      Why is this relevant to data?

      It's a very well known illustration of the concept of survivorship bias and if you're not interested enough in the topic to have encountered it before then it's unlikely you think enough about bias to be trusted to interpret data

          I had never seen this specific illustration, but I immediately recognized the anecdote from World War II and I knew what the OP meant.

          Like this it sounds helpful: “It's a very well known illustration of the concept of survivorship bias and if the Big Data person is not interested enough in the topic to have encountered it before then it's unlikely they think enough about bias to be trusted to interpret data.”

          It is not gatekeeping to expect a big data employee to have seen something they teach in 101 classes. It is their job to be able to interpret what the picture means.

          This is a good response to someone who claims to deal with data, but a shitty response to someone who doesn't

          You misread the post. 1. Answered what the picture is. 2. Answered why it is relevant.

          Wow so even though I'm well aware of survivorship bias and understand it just fine, the fact that I've never seen this before means I'm unfit to interpret data? Damn.

          Basically yeah because this is data knowledge 101. It’s like saying you’re a psychologist or sociologist studying/consulting about leadership and power positions and saying “Milgram? Never heard of him”.
