Still wouldn't call it bias. It's a quite rational belief that's based on insufficient data. Business decisions will change when more data becomes available. Bias will hardly.

Filtering data that suits your worldview happens just as easily to a CFO as it does to any armchair analyst on this site. Cognitive bias doesn't necessarily mean rampant fanboyism, hardly.
