4
There are no real black swans,
5
only white ones, aside from the soft grays and youth.
6
We have never seen a blue,
7
green, or rainbow-colored swan, and we have never seen a black one,
8
because they don't exist.
9
That is why, when we say something is a black swan,
10
we mean to say it is not real.
11
It is impossible.
12
This was the belief held across all of Europe prior to the 18th century,
13
just a little over 300 years ago.
14
Originating from the words of the second-century Roman poet Juvenal,
15
the phrase black swan was used exclusively to refer to something impossible,
16
similar to the idiom when pigs fly.
17
The reason for this was simple.
18
No one in Europe had ever seen anything other than a white swan.
19
All observations in historical records reported a consistent, clear reality.
20
white swans existed.
21
The problem, of course, is that black swans do very much exist.
22
They're not even rare in their native habitat.
23
They've existed abundantly for a very long time.
24
They were just unknown.
25
Only after the year 1697,
26
when Dutch explorers found black swans all over Australia,
27
did this reality, or rather the comprehension of reality, change.
28
Centuries' worth of consistent observations and subsequent expectations in phraseology revealed to be insufficient and false.
29
As if a pig suddenly flew,
30
what had previously been a symbol of impossibility suddenly became a symbol of humanity's inability to ever know what is
31
and isn't possible.
32
Black swans became a metaphor for unexpected events that undermine entire assumptions about truth.
33
More recently, the term black swan or black swan event has been popularized by the author,
34
statistician, and former options trader, Nassim Nicholas Taleb.
35
Across several of his books,
36
including Antifragile, Fooled by Randomness,
37
and The Black Swan, Taleb often explores the nature,
38
impact, and pervasiveness of unforeseen,
39
unpredictable, and history-altering events, many of which he refers to as black swans.
40
Taleb defines a black swan event as comprising the following three essential qualities.
41
1. The event comes as a surprise.
42
All prevailing models of understanding and prediction struggle to foresee or,
43
in some cases, even imagine it.
44
2. The event has immense impact,
45
reshaping major aspects of the world or how we see it. And 3.
46
The event appears completely explainable after the fact.
47
Contorted by retrospective rationalization, narratives are formed around the event that make seem clear or normal in hindsight.
48
Crucially, Taleb believes that most important historical events are black swans.
49
Scientific discoveries, artistic achievements, technological breakthroughs,
50
wars, global disasters, and major shifts in markets and ideologies are often black swans, according to Taleb.
51
He writes, History and societies do not crawl.
52
They make jumps.
53
They go from fracture to fracture with a few vibrations in between.
54
Yet we like to believe in the predictable, small incremental progression.
55
For Taleb, black swans reside on every landmass of society,
56
swim in every stream of consciousness,
57
and wade in every marsh of reality.
58
We see their presence in recent history in notable moments like the rise of the internet,
59
the 2008 financial crisis, the September 11th attacks,
60
the fall of the Soviet Union,
61
the formation of Einstein's theory of relativity,
62
and the discovery of penicillin.
63
Perhaps more unsettling than how immense the consequences of singular events
64
can be is what these black swans reveal about our comprehension of reality,
65
our expectations of the future,
66
and the limits of our ability to ever truly grasp either.
67
These outlier events can completely undo entire systems of logic,
68
knowledge, prediction, expectation, and operation.
69
They can uproot what we believed for centuries to be obvious,
70
break down what were once considered natural laws of the universe,
71
overhaul previously robust institutions, and generate,
72
seemingly out of nothing, entirely new realms of being.
73
And yet, prior to these world-changing moments,
74
even when they're just one step in front of us,
75
we never quite see them coming,
76
or at least we never act as though we do.
77
As a species, we struggle greatly with comprehending probability, odds, risk, and uncertainty.
78
As the historian and writer Yuval Noah Harari points out,
79
our ancestors were never obliged to handle large amounts of mathematical data.
80
No forager needed to remember,
81
say, the number of fruit on each tree in the forest,
82
so human Human brains did not adapt to storing and processing numbers.
83
Consequently, we are left, still today,
84
struggling to make sense of things at large scales.
85
Across long time horizons, large numbers or both,
86
order begins to blur into the appearance of randomness and chaos.
87
To sustain function, the human mind seems to bend around the variability,
88
uncertainty and chaos of the world,
89
filling in the gaps and solidifying itself like wet concrete,
90
turning otherwise unstable space into something solid and walkable.
91
we are left with is the illusion of stable ground and a reality that is set to break with a single step.
92
Perhaps our greatest offense in the realm of faulty intuition is that we tend to expect linear progressions.
93
In other words, we tend to believe that what has happened will continue to happen and in the same relative manner,
94
and that what has never happened will never happen.
95
This is the result of biases like the narrative fallacy and the availability heuristic,
96
where we tend to significantly simplify the recent past,
97
and then extrapolate this simplified version into the future.
98
Of course, when these biases are addressed explicitly,
99
we know it isn't the case that things always remain consistent or progress linearly.
100
On some level, we know that history is full of things that had never happened,
101
until they did, and we know that things once considered permanent have since ceased entirely.
102
But therein lies the rub.
103
Despite the apparent regularity of novel disruptions and turning points,
104
and despite our general awareness of them,
105
we still seem incapable of properly expecting or preparing for them,
106
whether it's on an individual or societal level,
107
whether it's mentally or systematically.
108
Although they do sound ominous and tend to relate to negative consequences,
109
of course, not all black swans are bad.
110
Just as often as they bring disruption or destruction,
111
they bring creation, advancement, and revelation.
112
The cosmos, the stars, earth,
113
life, these are all black swan events.
114
And of course, we ourselves are a black swan event.
115
An unlikely, unprecedented, self-aware, symbolic,
116
tool-making, existence-questioning species that nothing could have ever predicted before us,
117
that changed everything, and whose existence is now completely normal and obvious.
118
Only because of the apparent chaos and randomness of the cosmos do we exist.
119
And as beings forged by the very fire of chaos,
120
we can also learn to better handle and withstand the flames.
121
Another concept spearheaded by Taleb is known as antifragility.
122
This idea refers to things and systems that benefit and grow stronger through exposure to disorder and randomness.
123
This includes things like evolution,
124
the immune system, decentralized free markets,
125
airlines, the internet, and knowledge itself.
126
As these things are exposed to stressors or errors,
127
they adapt and strengthen, growing more capable of thriving under uncertainty in the future.
128
And of course, this also includes us.
129
If we are willing to take and face risks,
130
undergo potential harm, and move forward through an uncertain existence with mental fortitude and resilience,
131
doing our best to prepare for what we think will occur while accepting the events that actually do,
132
growing from them as they shape the course of history with and through us,
133
then we too can be antifragile.
134
Ultimately, we don't know what black swans might be lurking around us right now,
135
grazing in the shadows of unknowability,
136
floating in the mires of uncertainty.
137
We are always at the edge,
138
where light meets shadow, where stable land meets boggy ground,
139
projecting out in all directions our comfortable narratives of linearity and predictability.
140
But from the surface of our expectations all the way down into our most core beliefs,
141
so much of what we expect and hold to be true could reveal at any point,
142
suddenly and all all at once,
143
to be deeply flawed, incomplete, or flat out wrong.
144
The laws of nature, our position in the cosmos,
145
the very condition of the cosmos itself,
146
the realities of consciousness and selfhood,
147
our idea of what's right and wrong,
148
what's important and what our purpose is,
149
our expectations of the future.
150
We don't know what is true,
151
and we don't know what will happen.
152
But we don't need to.
153
At bottom, we don't even want to.
154
The apparent randomness and unpredictability,
155
as much as our minds work to smooth it over and fill in the cracks,
156
provide the slants, slopes, and gaps that thrill us, that build us.
157
If we wish to improve our experience in a chaotic universe,
158
perhaps instead of always trying to predict or control events,
159
worrying about what might happen or has happened,
160
we should learn to enjoy the birdwatching from the rollercoaster ride that is existence.
161
Something that very few people could have predicted just a couple decades ago is the economy built on personal information.
162
Who you are, what you like,
163
where you live, and so on,
164
are now all sought, packaged, and sold online.
165
What used to be the norm,
166
general privacy, has been upended.
167
A black swan made of data.
168
This video's sponsor, Incogni, is protection against the uncertainty and invasiveness of the modern world.
169
Data brokers are constantly obtaining your personal information,
170
like your name, social security number,
171
login credentials, home address, and so on,
172
by extracting it when you buy something or fill something out online.
173
They then sell the information to businesses,
174
marketers, and people's search sites.
175
Incogni works to stop this by automatically contacting these sites on your behalf and getting your personal information removed.
176
Legally, these sites must remove your information if you request it.
177
But doing this on your own is essentially impossible, time-consuming, and confusing.
178
That's why the data broker business model worked.
179
With Incogni, however, it's as simple as signing up and granting permission,
180
and then they take care of the rest.
181
And with the Incogni Unlimited plan,
182
you can even submit an unlimited number of custom requests.
183
By simply pasting the links to wherever your data is exposed,
184
including sites outside the automatic removal scope,
185
Incogni's privacy specialists will get it taken down.
186
The benefits aren't just peace of mind,
187
avoiding identity theft, fraud, or stalking,
188
but also peace and quiet.
189
Far fewer spam emails, texts, and robocalls.
