The A/B Testing Industry: Why Attitudes Matter

Article by Matt Gershoff about their approach and attitude to experimentation:

There is no ground truth here. There are just different attitudes and ways of seeing the world. But attitudes matter. They inform next steps and the most fruitful future directions to follow. Our view is that experimentation is of value not just in the doing but when it both helps clarify beliefs and makes assumptions explicit and as a process to iteratively update and hone those beliefs based on direct feedback from the environment.
