"How would you define good code? [...] After lots of interviews we started wondering if we could come out with a definition of good code following a pseudo-scientific method.

[...] The questionnaire consists in a single question: “What do you feel makes code good? How would you define good code?”. [...] Of those, the most common answer by far was that the code has to be Readable (78.46%), almost 8 of each 10 developers believe that good code should be easy to read and understand." -- "What is Good Code: A Scientific Definition"
