Many companies that aspire to achieve flat management ultimately fail to do so. Personally, I believe the most fundamental reason is that the leaders of these companies are not adept enough at selecting the right people. Flat management is inherently suitable only for collaboration among a group of highly cognizant individuals. However, in the real world, the distribution of cognitive ability follows the 80/20 rule. Even among graduates of prestigious universities, there are many whose educational background does not fully align with their actual cognitive level. When individuals with high and low cognitive abilities are placed on the same level, those with lower cognitive ability may struggle to understand the actions of their more cognizant peers, leading to disputes between the two sides. Additionally, even when individuals with lower cognitive ability realize they are wrong, they may stubbornly refuse to admit their mistakes to save face. This point was mentioned by Steve Jobs in one of his interviews.
