Long before Blueprint made him a public figure, Johnson wrote extensively about what he calls “future literacy,” the ability to plan effectively for outcomes that haven’t yet taken shape, and the mental habits that quietly get in the way of doing so. Bryan Johnson co-founded the payments company Braintree, which was later acquired by PayPal, and went on to found the brain-interface startup Kernel before becoming globally known for Project Blueprint, his intensely data-driven effort to reverse his own biological aging. This quote, drawn from that body of writing, captures one of his central ideas about why people struggle to plan for the future well.
This distinction comes out of Johnson’s writing on what he calls the “familiarity bias,” the tendency of people to feel safest around what they already know and to instinctively downplay or resist what is unfamiliar. The more useful question isn’t “how do I get more certain,” but “am I avoiding this because it’s genuinely unwise, or simply because it’s unfamiliar,” a distinction that can separate genuine foresight from comfortable conservatism dressed up as caution. “To me, future success depends upon our ability to not confront our future biases but to actively embrace uncertainty. The quote draws a distinction that’s easy to miss: confronting a bias and embracing uncertainty are not the same action. Confronting a bias implies identifying it, reasoning through it, and correcting for it, a process that treats not-knowing as a problem to be solved before moving forward. Johnson argues this approach is insufficient on its own. Instead, he frames uncertainty as something to be actively embraced, a standing condition to operate within rather than a temporary obstacle to eliminate before acting. He has argued that this bias served humans well for most of evolutionary history, when the unknown often posed real physical danger, but has become a liability in an era where technological change routinely produces futures that look nothing like the past. Most conventional advice about handling uncertainty treats it as a temporary discomfort to push through: gather more information, build more confidence, then act. Johnson’s framing suggests that approach can itself become a trap. If people wait for uncertainty to resolve into clarity before committing to a direction, they risk mistaking the discomfort of not-knowing for a legitimate signal to hold back, when in fact that discomfort may simply be the familiarity bias doing exactly what it evolved to do. Johnson isn’t arguing that caution or information-gathering are worthless. His point is closer to a warning: that fear of the unfamiliar can disguise itself as prudence, producing a conservatism that feels reasonable in the moment but that quietly narrows the range of futures a person or organization is willing to consider. In a period of fast-moving technological change, he argues, that narrowing becomes a much bigger risk than it once was. The quote’s underlying logic extends well beyond individual choices. Organizations, institutions and entire fields of research face the same dynamic: the more unfamiliar a possible future looks, the more natural it becomes to dismiss or under-invest in it, even when the underlying evidence doesn’t justify that dismissal. Johnson’s broader writing suggests that recognizing this pattern, in ourselves and in the groups we’re part of, is a prerequisite for making good long-term decisions, not an optional afterthought. This doesn’t mean treating every unfamiliar idea as automatically correct either. It means treating discomfort with the unknown as information about our own psychology first, rather than as reliable information about the idea itself. Johnson’s quote works as a corrective to the assumption that clarity must come before action. Uncertainty isn’t a barrier to be cleared before real planning can begin; for Johnson, it’s the actual terrain that future success gets built on. Get the latest technology news and updates.
