This is an interesting comment. In my experience most people were right in their way of thinking. Even if they come to vastly different conclusions, most of the time they are kind-of-right. This continues until objective reality hits as in "can we ship" and "does it make money". And even then it depends on many factors with many people involved. For a vision like VR this is far into the uncertain future and "being right" can mean many different things to people. Data doesn't help much if it is biased, if the analysis is biased or if you just have different definitions and priorities.

At the end of the day the real struggle is achieving alignment on business goals and priorities across the whole team. And also aligning them with reality. This is usually where you elect one leader to define those things and the others to follow those definitions.
