Nassim Taleb's Black Swans: How to Build a Business in a World Where Tomorrow Is Not Guaranteed
Survival strategies are more important than growth strategies
Taleb criticises forecasting models based on ‘averages’ (of price, income, demand or exchange rates), as they ignore extreme and unlikely scenarios. In statistics, these are known as the ‘fat tails’ of a distribution, but in reality they are the events that determine the fate of countries, markets and corporations. Forecasts based on average figures often distort reality and create an illusion of control. But it is precisely the peak loads and extremes-which analysts dismiss as ‘unlikely statistical errors’-that cause everything to break.

Anti-fragility is the key idea, or more precisely, Taleb’s philosophy: most systems are either fragile (they break under stress) or simply invulnerable (they withstand shocks). A fragile business fears any kind of change. An invulnerable one has ample reserves and may therefore fail to notice problems that later come crashing down on it all at once. An anti-fragile business moves from ‘enduring and surviving’ to ‘capitalising on chaos’. It capitalises on market upheavals and competitors’ mistakes.
So, what should you do and what should you avoid in order not to fall victim to forecasts? Nassim Taleb’s principles of resilience and anti-fragility.


1. Don’t try to predict the future; prepare for it instead
Instead of asking ‘What will happen?’, it is more useful to ask: ‘What could bring us down?’ and ‘What solutions will keep the business afloat when things go wrong?’. A good strategy starts with a list of critical risks and pre-defined responses: what do we do if demand falls, supplies are cut off, interest rates spike, payments are blocked, or a key client leaves? It is vital that the business is prepared and able to survive the worst-case scenario, even if the probability of it occurring is low. The principle is simple: ‘how not to lose everything’ is more important than ‘how to maximise profits’.


2. Diversification and creating ‘safety buffers’ are more important than accurate forecasts
Optimising down to the last penny is a recipe for disaster at the first sign of a crisis. Buffers (cash reserves, alternative suppliers, spare capacity) are the price you pay for stability. In the accounts, a buffer looks like an expense. In a crisis, it helps you survive.


3. Prepare for the unexpected, not for a specific scenario
The most significant events occur unexpectedly, which is why they have such a powerful impact. ‘Black swans’ are dangerous not because they are ‘rare’, but because they come from where they are least expected.

It is essential to draw up a contingency plan in advance for various scenarios: a collapse in demand, currency fluctuations, rising interest rates, regulatory bans, payment freezes or disruptions to the supply chain. Uncertainty must be translated into specific parameters. Instead of asking ‘what will the exchange rate be?’, one needs to understand ‘what will happen if the exchange rate falls by 20% and this lasts for six months’. Instead of asking ‘will there be a disruption to supplies?’, one must know in advance ‘what we will do if supplies become unstable’.
We overestimate predictions and underestimate uncertainty. Many events that appear logical and predictable turn out, upon closer examination, to be a combination of random factors. Nobel laureate Daniel Kahneman, the ‘father’ of behavioural economics, has demonstrated that people are obsessed with finding patterns and systematically invent cause-and-effect relationships. Nassim Taleb took this a step further by introducing the concept of ‘black swans’ – rare, unpredictable events with catastrophic consequences.

Wars and armed conflicts, the unpredictability of politicians, currency fluctuations, pandemics and natural disasters are shaking up our world, which until recently was relatively calm. Tariffs and duties are rising, supply chains are becoming more complex, and legislation is changing. LLC "EIFOS HUB" has decided to examine Taleb’s ‘black swans’ from today’s perspective, when it is impossible to predict what might happen tomorrow. We offer you an in-depth analysis of the principles based on Taleb’s concept, with explanations of all the key concepts.
4. ‘Skin in the game’, ‘intellectual idiots’ and experts
In business, you cannot trust those who do not put their money, reputation or position on the line alongside you, argues Taleb, who advises checking whether counterparties and consultants have ‘skin in the game’.

Analysts’ forecasts often fail to materialise because they are based on the past. In psychology, this is known as the hindsight bias: once a disaster has already occurred, analysts instantly find ‘logical’ explanations for it and insist that the event was predictable. In reality, this is merely an attempt to save face.

According to Taleb, reading the news and other information sources does not actually increase, but rather diminishes, our awareness and knowledge of the world.


5. To understand the nature of success, be sure to study failures
Success is often random, whilst failure is always systematic and recurrent. The ‘survivor bias’ shows us only success. But we know nothing about those who did the same thing and went bankrupt. Businesses fail due to: over-reliance on a single client, excessive debt, cash flow gaps, or dependence on a single platform or a single country for logistics. It is therefore useful to study bankruptcy reports, post-crisis analyses and court cases.


6. The ‘Barbell’ Strategy in Investing
Don’t look for ‘medium risk’. Invest ‘at the extremes’, in measured doses, as Taleb writes, using a ‘ladder’ approach and without trying to predict the ‘bottom’ (the lowest point of a price fall): 90 per cent of your investments should be in the most reliable assets, and 10 per cent in high-risk ideas with the potential for explosive growth. If 10% goes up in smoke, you won’t go bankrupt. If it ‘takes off’, you’ll make a multiple of your investment.


7. Via Negativa: the power of subtraction
Removing weak links has an immediate effect and requires no forecasting. Often, the best way to reduce risk is not to ‘introduce yet another tool’ but to remove the unnecessary: toxic clients, a single critical dependency, complexity that nobody understands, or long-standing accounts receivable.


Conclusion: How to Manage Chaos
Traditional planning methods no longer work today. To keep a business afloat, you need to accept that:
  • The world is no longer predictable, and making forecasts is irrational. LLC "EIFOS HUB" recommends ‘safety buffers’: a reserve or projected inflow of ‘liquid’ funds, and regular inflows to cover essential expenses even in a ‘zero’ month.
  • You need to structure your business so that, whatever changes occur (including ‘black swans’), you retain the capital to manoeuvre.
  • Complexity is a risk. The more complex the business structure, the easier it is to break. Simplify everything: from legal structures to decision-making chains.
  • Portfolio resilience is not about forecasting, but about being prepared for any scenario. Shares, bonds and other cash equivalents react differently to inflation, recessions, rising interest rates and geopolitical events. Allocate assets across asset classes and sectors suited to different market cycles. Over a two- to three-year horizon, this strategy is more effective than attempts to outsmart the market.
  • Those who survive today are those whose businesses can benefit from uncertainty or, at the very least, are not destroyed by it.
