Simone Stolzoff describes himself as “naturally an uncertain person” inclined to rumination and self-doubt. This tendency benefits him in his work as a journalist, but can otherwise be a double-edged sword. While working for a magazine in New York, Stolzoff was approached about a job at a design firm in San Francisco. Now, he laughs at how tortured he felt “having to decide between two attractive career paths”. But, at the time, “it really sent me for an existential loop,” he says. “I could see these two diverging paths – Simone the journalist, Simone the designer – and, for the life of me, I could not make up my mind.” Stolzoff talked his options through – with everybody. “My yoga teacher, my Uber driver, all my friends and family …” He grimaces. “I was insufferable.” He wound up choosing the San Francisco job: a new home, an unfamiliar industry. The experience informed his new book, How to Not Know: The Value of Uncertainty in a World That Demands Answers. Looking back, Stolzoff says over video-call from his home in the Bay Area, his mistake was aspiring to feel certain: “It was my intolerance of uncertainty that was causing so much of the angst.” Trying to anticipate the future and make plans with confidence is unique to humans, and evolved to keep us safe. But, especially in these uncertain times, it can easily lead us astray, says Stolzoff: “We have these brains that are wired to get out of uncertainty as quickly as possible, in a world where there are triggers all around us.” Because the future is unknowable, the real question is how we can learn to cope better with not knowing, Stolzoff says. Our conversation has been condensed and edited for clarity. Why did you write this book? My first book, The Good Enough Job, is about how work came to be so central to our identities. The most common question asked by readers was “How should I think about the future of my career, given AI and all these other changing forces?” View image in fullscreen How to Not Know by Simone Stolzoff.

I wanted to throw my hands up and say, “I was a poetry student, for God’s sake.” That is not a very gratifying response to receive, so I wanted to explore this question of uncertainty, and not just insofar as it relates to career. The cliche is that you write the book you need to read – I went on this multi-year journey of exploring the science and psychology of uncertainty partly so that I could hopefully get better at dealing with it myself. double quotation mark The best way to increase your tolerance for uncertainty is through exposure The modern world is often said to be acutely, even uniquely turbulent, but we also know more about it than ever. Why might we be struggling in this moment? It is a precarious time. Stanford economist Nicholas Bloom has been studying global uncertainty since the early 1980s; the five highest measurements all occurred in the past five years. What I think is novel is the fact that our tolerance for uncertainty is in decline. Research has found a correlation between this and the rise of the internet, and more particularly smartphones. These pocket computers create the expectation that answers should be readily available. Ten years ago, I might have been OK with not knowing the name of some actor; now I feel an almost involuntary need to find out right away. They also bring all of the world’s uncertainties to the fore. But often these real-time updates and access to information just fuel our anxiety, and rob us of practice in sitting with what we don’t know. The best way to increase your tolerance for uncertainty is through exposure, and resisting easy answers, but the internet makes it much easier to avoid that discomfort. Are there benefits to becoming more comfortable with uncertainty? Many people are unwilling to face uncertainty head on. They might know their job or relationship isn’t working for them, but would rather stick with the devil they know. But by being willing to embrace the unknown, you may discover something that was greater than what you could have anticipated. I hope people come away from the book understanding that, yes, uncertainty can be threatening, but it is also the birthplace of possibility. If you’re willing to tolerate it for a bit longer, you can discover new things about yourself, others and the world. There’s also a clear mental-health case: our brains tend to think about the worst-case scenario, and catastrophise. A lot of our anxiety is driven by worrying about things that haven’t happened yet. I think there would be a lot of collective health benefits if we could be more OK with what we don’t know. Uncertainty can register as a threat, triggering the fight-or-flight response. Should we think of uncertainty intolerance as a physiological issue, as much as a psychological one? We spend so much time up in our heads – particularly knowledge workers, like you and me – but a lot of wisdom is emb
