What I’ve been reading this week
Part 1 in a multipart series about decision making and experimentation at Netflix.
At Netflix, we believe there’s a better way to make decisions about how to improve the experience we deliver to our members: we use A/B tests. Experimentation scales. Instead of small groups of executives or experts contributing to a decision, experimentation gives all our members the opportunity to vote, with their actions, on how to continue to evolve their joyful Netflix experience.
ps. Netflix is looking for an Experimentation & Causal Inference Intern
A/B testing is rarely used for comparison between whole builds. That’s because each build integrates multiple feature changes and it is hard to figure out which features cause regressions, if any. However, the Microsoft Teams Experimentation team did make an attempt to use A/B testing as an integration testing tool for builds comparison.
Bhavik Patel suggests we start calling it ‘Lighthouse Metric’, not NSM.
In this study the authors look at 50 types of dark patterns across the desktop web, mobile web, and mobile app modalities of 105 services. Most used dark patterns are privacy related, see table below.
Jan Bosch explains why:
A/B testing is relevant in any context where a mathematical optimum can’t be established easily. As such, it’s relevant for virtually any company and system. With the increased connectivity of systems and a continuously growing expectation of improvements to systems throughout their entire economic life, it’s clear that A/B testing is a capability that every industry, company and team needs to build up.

Google asked Ipsos to interview thousands of people about their personal privacy and data. Three tips for defining your data strategy:

- Make it memorable
