Confirmation bias exists almost everywhere. Confirmation bias especially among senior management is highly dangerous as decisions are based on not on data and facts, rather they are based on anecdotes, hunch/feelings, with high probability of going wrong. This is precisely where data scientists play a significant role, by providing recommendations and presenting facts based on hard data and mathematical models, in order to ensure that senior management decisions are based on facts/data, and not on anecdotes and hunches. Furthermore, a data driven organisation must have a supporting culture, where data driven decisions are given precedence, and data scientists (data messengers) must be empowered to present facts as is, no matter whether these facts are aligned or not with the basic assumptions and biases held by the senior management team. Creating such a supporting organization culture is extremely important but definite not easy. Culture is one of the factors that makes a difference between success or failure in a data driven organisation.
