“The best way to verify that you are alive is by checking if you like variations. Remember that food would not have a taste if it weren’t for hunger; results are meaningless without effort, joy without sadness, convictions without uncertainty, and an ethical life isn’t so when stripped of personal risks.”
Last time we explored the idea of antifragility – what, though, are its implications? Taleb has but one core lesson; we cannot escape or prevent volatility, so we must love it, and we can only do that if we are antifragile.
To do so, focus on doing, not on theory. Taleb argues that progress comes from small advances by doers, while theorists usually just post-hoc justify the progress of doers. As Yogi Berra tells us, “In theory there is no difference between theory and practice; in practice there is.” [Nick Note – I’m not sure I agree with this, and will object below, but I thought I’d pass it along anyway]
Second, focus on dispersion, not just on averages. For a stock portfolio, for example, don’t have all your money in a fund with moderate risk/return; put 10% in an extremely risky fund with a large upside, and the other 90% somewhere very safe. We are best, he argues, when faced with alternating periods of recovery and high intensity, whether we are talking weight lifting, investments, diets, or emotions.
Third, obey nature in the absence of opposing evidence. Taleb follows Burke, arguing that the burden of proof always lies with the unnatural or new. The natural or traditional has been tried and turned antifragile through an evolutionary process, while the new has not. It’s a principle he lives by; on breaking his nose and failing to find empirical evidence of the value of ice, he dutifully refused ice. I can only respect his adherence to principle.
Fourth, value heroism. Heroes, Taleb points out, are people who sacrifice for the community; they are extremely antifragile, taking society’s risks on themselves. As a society, we should only respect people who take risks for their opinions. Roman engineers, for example, were required to stand under their bridges after they were built, while bankers in Catalonia were beheaded if their banks failed. Consultants and investment bankers today, on the other hand, bear almost no risk from their advice. This, Taleb argues, is the core problem with capitalism; the basic unit of interaction is the corporation, by means of which no individual bears any risk for their decisions.
It can sometimes feel like Taleb is taking an unjustifiably extreme position to provoke controversy – perhaps it’s effective, but it’s also somewhat annoying. He is convincing that practical knowledge is undervalued, for example, but that is hardly the same as showing that theory is always useless. More generally, his book can sometimes feel a bit one sided, as he writes to convince, rather than to inform. That aside, the book is phenomenal; Taleb is one of the foremost thinkers of our age, and if he sometimes seems overeager to support his own ideas, the rest of the time is he is truly wise. He’s also, by the way, one of the rare authors who can throw in a line like “Genoa and Venice were competing for the Eastern and Southern Mediterranean like two hookers battling for a sidewalk.”
You can get your copy here (or in the UK or Canada), and it’s definitely worth a look. Antifragility is a concept all of us could benefit from.
