I think fundamentally, if you have incomplete information and have to make some actions or judgements, either you are:

1. doing things to reason about or uncover more useful datapoints to increase certainty

2. you are accepting the probability that you are right/wrong at face value

The direction in which you decide to uncover datapoints is the "bias" that they are talking about. This process if further influenced by institutionalized assumptions or priors you are working with.

I really don't like lists like "Strategic Assumptions That Were Not Challenged" because they are factually true but also reek of survivorship bias.
