Can credibility be borrowed? Does “fake it ’til you make it” actually work?
The Third Door by Alex Banayan is a compilation of what Banayan learned about success—not only from the people he interviewed—but also from the process of pursuing them. From his interviews with Tim Ferriss, Bill Gates, and Maya Angelou, he learned about the importance of credibility.
Keep reading to learn how these three life stories illustrate how credibility is a key to success.
Importance of Credibility
Banayan purposefully chose interviewees who had, like him, started their careers as unknowns, and therefore faced a lack of credibility as they tried to get established. Several of the people he spoke with talked about the importance of credibility and shared personal advice on how to convince others to invest in you before you have a proven track record.
(Shortform note: Credibility is defined as trustworthiness or the ability to inspire belief. In the business world, credibility is an essential part of establishing your company or career—without it, you’ll struggle to attract customers, employees, investors, and partners, or to get favorable terms for loans or contracts.)
Tim Ferriss: Borrow Credibility
Tim Ferriss, entrepreneur, life coach, and author of The 4-Hour Workweek, a best-selling book about how to achieve success with minimal effort, told Banayan that an effective way to gain credibility is to borrow it from a more credible source.
To do so, volunteer for credible nonprofits or write for recognized publications. By doing so, you can associate your name with their expertise—you’ll get a lot further contacting a potential business partner by saying you’re, for example, a project coordinator with a known organization, or that you’ve been recently featured on a credible website, than you will by saying you’re a recent college grad.
(Shortform note: Borrowing credibility works because people are hardwired to trust the opinions of others. As Robert Cialdini explains in Influence, this is part of the social proof principle—the idea that we decide what to do or think by following what others do or think. This is a mental shortcut that helped us survive: By trusting the opinions of others, we could quickly determine what was dangerous or where opportunities were. The social proof principle has stayed with us as we’ve evolved, and it’s why we trust an unknown entity (in this case, someone starting their career) if they’re “trusted” by a source we already trust.)
Bill Gates: Know Your Stuff
When Bill Gates, co-founder of Microsoft, was trying to close a deal with IBM in 1980, he faced a credibility problem. IBM was the world’s largest tech company at the time, and landing a deal with them would allow Microsoft to dominate the tech field for decades. But, he was the youthful-looking head of an unproven startup. He had to convince IBM executives that he was a serious player in the field and could be trusted with their business. To do this, he went into their meeting armed with knowledge not only about his product but also about IBM itself.
Know Your Product
Gates convinced IBM executives of his expertise in his product by talking fast and overwhelming them with detailed, technical answers to questions they raised. By discussing in-depth aspects of programming and software, he made it known that his knowledge outpaced his youthful looks.
Know Your Client
Gates also leveraged his knowledge of IBM’s desires and fears to secure a more favorable contract than would have been expected of his new and inexperienced company. Desires: He knew IBM valued speed so he emphasized how fast his company could deliver—even deliberately overpromising what Microsoft was capable of at the time. He did so knowing that if he said what they wanted to hear, they’d be more inclined to work with his company.
