Groupthink can be compared to a barrel of monkeys fighting for the same banana. The goal is to get the banana, each monkey knows it, and is compacted into a minimalistic mode of thinking to fight for the same object no matter the consequences. Whereas if they all just escaped the barrel, they would realize there are more bananas outside the barrel. With this analogy, it can be proven that groups are often narrow-minded to what is only true within their individual scope of understanding; completely disregarding any outside possibilities. It is truly this limiting factor that leads to little or no alternatives within the group.
