The key insight though, is that dominant individuals tend to respond to assertions of dominance with their own return assertion of dominance. In other words, they don't like being dominated, and it's this reaction VCs are typically looking for as dominant behavior is likely perceived as a requisite character trait for entrepreneurial success. Programmers though tend to conversely be a prestige driven culture and respond negatively to dominance challenges like this.
