Herd Mentality

When people follow the leader or others like a herd instead of thinking independently. Often seen when investors are deciding which startups to fund.

VC: You guys have a really strong team, exactly the type that we like to fund, but we just don't believe in the idea.
Kim: Did I mention that a16z decided to invest in us yesterday.
VC: Wait. Don't leave. I think we started things off on the wrong foot.
