Of course, like with many things, there is also an offset bias to the familiarity bias, the exploration bias. While we tend to be strongly biased towards things that we know, there is also a bias towards the unknown and the opportunity to explore and learn. This bias tends to be extremely weak compared to the familiarity bias, but far from trivial in many IT practitioners. It is a bias that should not be ignored and is important for helping broaden the potential scope of advice from a single consultant.
