What Hinders Rethinking

According to Adam Grant, there are three modes of thought that hinders rethinking. He calls them preaching our own beliefs, prosecuting others' thoughts, and politicking for acceptance and validation. He says, when we lack the knowledge and skill to achieve excellence, we sometimes lack the skill and knowledge to judge excellence. We become blind to what we do not know. I think this is where we fallback onto herd mentality and find solace in group thinking.
