* decision anxiety

Real engineers proceed on the basis of evidence and in the absence of evidence make arbitrary original decisions as necessary to gather evidence.
The problem space there comes from only two considerations. The first of which is a team where nobody has the required prior experience. In that case confidence drops in proportion to the increase of uncertainty, but that does not necessarily result in an increase of anxiety. Some people and/or work cultures are much better positioned than others to confront stress directly without distressing towards anxiety.
The second consideration is the collision between prior experience and evidence. In this case both the evidence and the prior experience must be considered and an alternate conclusion must be reached. That alternate conclusion is the definition of truth according to John Stuart Mills.
