The 'Do or Do Not' Fallacy How a Twisted Growth Mindset Destroyed Theranos

Can a single line from a science-fiction movie cause a multi-billion-dollar business to collapse? A healthy growth mindset suggests that intelligence and abilities are developed through persistence, learning, and the courage to admit when a current approach isn't working. At the failed startup Theranos, founder Elizabeth Holmes inverted this idea by using Yoda’s famous catchphrase to silence scientists and engineers. She demanded results that defied the laws of physics and punished anyone who suggested that the company's technology was failing.

Why the Silicon Valley Work Ethic Replaced Real Testing

In his book Bad Blood, John Carreyrou details how the 'Do or do not' philosophy became a toxic tool for management. Holmes and her partner Sunny Balwani used the quote to create an environment where 'trying' was viewed as a lack of commitment to the mission. They viewed the engineering process not as a series of experiments, but as a test of personal loyalty to the company. When experts pointed out that blood samples were being diluted beyond recognition, they were told that a person with a true work ethic would simply find a way to make it work.

This mindset is dangerous because it ignores the reality of scientific discovery. Science requires the freedom to try and fail until a solution emerges. At Theranos, the valuation reached a staggering $9 billion because the leadership prioritized the appearance of success over the accuracy of the lab results. By the time the company launched in Walgreens stores, it was performing only a small fraction of its advertised tests on its own proprietary devices.

How the Silicon Valley Work Ethic Inverted Progress

Why Binary Success Kills Technical Innovation

When a leader demands that a team 'do or do not,' they remove the middle ground where actual learning happens. Engineers at Theranos, like those working on the 'miniLab' project, were forced to meet impossible deadlines based on arbitrary aesthetics rather than mechanical feasibility. When the devices' robotic arms crashed or centrifuges exploded, the failures were hidden rather than analyzed. This approach effectively killed the growth mindset because it made the fear of failure more powerful than the desire for truth.

Why the Silicon Valley Work Ethic Requires Constant Feedback

Silicon Valley often celebrates a 'fake it till you make it' culture, but there’s a hard line between marketing hype and medical fraud. Holmes and Balwani believed that sheer willpower could overcome the fact that their 'Edison' devices produced wildly inaccurate potassium and sodium results. They ignored the fact that 100,000 Americans die annually from adverse drug reactions, a statistic Holmes used to justify her mission while ignoring the safety of her own tests. Their work ethic was focused on the next funding round rather than the health of the patients they served.

Transforming the Growth Mindset into a Shield for Fraud

In a healthy business, persistence is used to overcome obstacles, not to ignore them. The leadership at Theranos used the idea of persistence to justify 'jailbreaking' Siemens machines to run diluted samples. They told employees that this was a temporary necessity for a world-changing goal. By reframing dishonesty as a 'competitive advantage,' they ensured that anyone with a moral compass was eventually forced to resign or be fired. This created a bubble of sycophants who were too afraid to report that the 'revolutionary' technology was a sham.

Lessons from the Fall of a Unicorn

The most prominent example of this fallacy was the 2013 launch of Theranos's blood-testing services in Phoenix. Elizabeth Holmes and Sunny Balwani insisted on a commercial rollout despite their lab director, Alan Beam, warning them that the technology was not ready. Beam pointed out that blood-test results for thyroid and potassium were consistently unreliable. Instead of pausing to fix the science, Holmes used her high-profile board of directors to shield the company from scrutiny. They relied on the reputations of men like George Shultz and Henry Kissinger to project a false image of technical mastery.

Another story involves Ian Gibbons, the company's first experienced scientist. Gibbons was a Cambridge-educated biochemist who realized that the Theranos technology was fundamentally flawed. When he tried to voice his concerns to the board, he was marginalized and eventually fired, then rehired as a consultant with no real authority. The pressure to 'do' without the freedom to 'try' and speak the truth eventually led to a tragedy that the company's leadership callously ignored. This lack of empathy is a hallmark of a culture where the mission is used to justify the destruction of the people performing the work.

Moving Toward Technical Truth

1. Reclaim the Scientific Meaning of 'Try'

Leaders must explicitly define 'trying' as a rigorous process of testing and gathering data rather than a lack of effort. In high-stakes industries like healthcare or engineering, failure is an essential data point that informs the next version of the product. Encourage your team to bring you the data that proves a system isn't working today. This shift ensures that persistence is applied to solving the problem rather than hiding it.

2. Reward the Messenger of Bad News

Create a formal process where technical roadblocks are reported and celebrated as opportunities for course correction. If a scientist or engineer highlights a mechanical failure, they should be rewarded for protecting the company’s reputation and safety. This breaks the 'binary success' trap that forced Theranos employees to commit fraud to avoid termination. A culture that welcomes dissent is far more resilient than one that demands blind obedience to a quote.

3. Separate Mission from Mechanics

Ensure that the emotional weight of your company's mission doesn't cloud the objective reality of your product's performance. Elizabeth Holmes used the tragedy of her uncle's death to justify skipping essential validation steps in her lab. Keep your vision high, but keep your standards for technical evidence even higher. Verify that your growth mindset is focused on improving the product's accuracy rather than just the company's valuation.

Where Traditional Mindsets Fall Short

Critics of this approach often argue that 'failure is not an option' is a necessary mindset for high-performance teams. They point to the Apollo 13 mission as proof that absolute commitment to a goal can produce miracles. However, the engineers at NASA relied on math, physics, and brutal honesty to bring the astronauts home. They didn't ignore the carbon dioxide levels; they acknowledged the failure and worked within the constraints of reality to fix it.

At Theranos, the leadership used the Yoda quote to ignore the constraints of reality. Critics of the 'growth mindset' concept itself warn that it can be misinterpreted as a 'power of positive thinking' exercise. When a mindset is used to deny evidence, it is no longer a tool for growth; it is a tool for delusion. A truly resilient business culture recognizes that sometimes the most courageous 'do' is to stop a failing project before it causes real harm.

Effort alone cannot fix broken physics or faulty chemistry. A genuine growth mindset requires a team to acknowledge failure as a necessary step toward technical truth. Audit your current dissent procedures to ensure that employees can report technical roadblocks without fear of retaliation.
