Dan McKinley :: Effective Web Experimentation as a Homo Narrans
Good demo from Etsy’s A/B testing, of how the human brain can retrofit a story onto statistically-insignificant results. To fix: ‘avoid building tooling that enables fishing expeditions; limit our post-hoc rationalization by explicitly constraining it before the experiment. Whenever we test a feature on Etsy, we begin the process by identifying metrics that we believe will change if we 1) understand what is happening and 2) get the effect we desire.’

Lesser known crimes: do you own that copyright?
A very interesting crime on the Irish statute books:
Section 141 of the Copyright and Related Rights Act 2000 provides: A person who, for financial gain, makes a claim to enjoy a right under this Part [ie. copyright] which is, and which he or she knows or has reason to believe is, false, shall be guilty of an offence and shall be liable on conviction on indictment to a fine not exceeding £100,000, or to imprisonment for a term not exceeding 5 years, or both.
