Many of us are familiar with individuals who believe they are experts in everything, regardless of their knowledge. These individuals are often referred to as "know-it-alls."

Jason Buechel dedicated eleven months to preparing for his role as the head of Whole Foods before assuming the position in September 2022. During this time, he gained valuable insights from co-founder John Mackey, the brand's CEO for 42 years.

The Harm of Being A Know-It-All

Buechel, the CEO of the Amazon-owned grocery chain Whole Foods, readily shared with CNBC that it is his least favorite among the various individuals encountered in the workplace. It is someone who believes they have the answer to everything and insists on maintaining the status quo because it has and will always happen that way.

While many know-it-alls may not intend harm with their behavior, interacting with them can often be challenging. However, for some know-it-alls, their behavior may stem from a deeper issue, which can exhibit judgmental, harsh, and overbearing behavior, often taking pleasure in asserting their superiority during conversations, particularly when others are present.

Buechel acknowledges that he might have exhibited traits of someone who thinks they knows everything in the past and learned flexibility the hard way, especially in today's ever-changing business landscape, where customer demands constantly evolve and change the business. He adds that sticking to rigid ways of doing things or ignoring others' perspectives can significantly impede personal and even your company's growth. 

The Positive Implications of Flexibility

Take team dynamics, for instance. With new hires, departures, and promotions, work teams are constantly in flux. Adaptable leaders can seamlessly adjust to these personnel changes, while adaptable employees can proactively seek new ways to contribute to the team.

Consider constructive feedback. Failing to actively implement your boss's critiques of your work can give the impression of inflexibility and an inability to accept criticism.

Flexibility proves to be a valuable attribute in many workplaces. Amazon CEO Andy Jassy emphasizes the importance of relinquishing a know-it-all mentality for success. Believing you know everything is when things start to unravel, Jassy emphasized during an appearance on LinkedIn's The Path podcast last month.

Embrace new opportunities to learn and maintain a sense of curiosity. Jassy highlighted how this approach can keep individuals engaged in their careers and hobbies, leading to greater happiness and improved ability to navigate the inevitable challenges encountered throughout one's professional journey.

Some individuals reach a point where learning feels threatening. Jassy emphasized that the most accomplished individuals possess an insatiable appetite for learning. 

Jassy pointed out that the significant disparity between the people he began his career with and their current achievements is primarily attributed to their ability to learn effectively. He added that there is a vast array of new knowledge, opportunities, and relationships that individuals can access if they allow themselves to do so.
