For students of Swanology, the #1222 episode of the Joe Rogan Experience podcast is a gem. It illuminates several of the mechanisms involved in turning some (most) of us into suckers, and highlights the enormous differences in expectations that can arise even when we are looking at the same set of facts. The topic of conversation is about the mother of all Black Swans, the wiping away of the existing world order by way of an asteroid impact. According to Rogan's guests, Graham Hancock and Randall Carlson, there is compelling evidence to suggest that there have been repeated cosmic impacts during the 180,000 years or so that anatomically modern humans have existed. Besides transforming the geography of the Earth, these events may have erased civilizations existing at the time so thoroughly that no archaeological evidence of them can be found today. Hancock and Carlson, labelled ‘catastrophists’ by some, argue that human civilization did not begin to stir around 12,000 years ago, which is the conventional view, but that it was rebooted following a near‐complete destruction caused by an asteroid that smashed into Earth a number of centuries before. The asteroid impact they refer to was followed by extreme shifts in the global climate. One consequence was a near‐instantaneous melting of the ice sheets and the flooding that resulted completely overwhelmed humans living at the time. (Fascinatingly, if true, this could explain the enduring myths handed down to us from deep history regarding an epic flooding.)
Mainstream science, however, adheres to a view referred to as ‘gradualism’, which holds that we can extrapolate backward in time from processes we are able to observe today. In this view, everything we see in the landscapes today are the result of gradual processes that have been going on for eons. As a result of the vested interest in this narrative by academics who have built a career on it, they have put up quite a resistance to the ideas put forth by Hancock and Carlson. This resistance takes us into Black Swan territory with respect to the civilization‐destroying potential of cosmic impact. Below are some excerpts from their conversation. We do not have to take any sides with respect to the facts being discussed to enjoy the insights it brings about the Black Swan formation process.
GH: | Whenever you propose a cataclysm and present evidence for it … you can be sure that you will be descended upon by a crowd of furious critics. |
JR: | As a species, we have amnesia. |
JR: | Why would they try to ignore something like that? |
GH: | When new information emerges that contradicts established theories … when you get very committed to a model or idea … you start to connect your personality to it, and any attack on it becomes an existential attack on you. |
GH: | Again and again, what we see is new facts being dismissed because they don't fit into the existing theory … this is a problem in the whole history of science. I've come to view archeology and history as more ideology, really, than science. |
GH: | There is an ideological view of how civilization developed, that there is this long, slow, gradual, politically correct rise … and here we are, the apex and pinnacle of this story, and gosh, we are so proud of ourselves and our achievements. |
GH: | They are in a state of denial and just don't want to recognize it. |
JR: | It is so sad. You count on these people to distribute the information but their ego gets involved in things … if you have an absolutely established narrative that you teach and you are unwilling to look at any possible deviation from that, you are saying, almost from an authority position, ‘we know what happened and we know where we are going’. |
RC: | We're kind of in this mode now where there's a very large and growing political agenda around the idea that humans are the sole cause of global change … now we come along and say, no, there's actually been forces unleashed on this planet that utterly dwarfs anything we've done yet. What does that do to that paradigm? |
GH: | … south of Minnesota you [had] a heavily vegetated area covered with primal forest and that is what goes on fire and the reason it goes on fire is because when these impacts come in they generate huge amounts of heat … and it [sets] the world on fire. |
JR: | Oh that gives me goosebumps … a single afternoon all over the world and everything changes forever and it's [ruined] for a thousand years. |
GH: | We all need to know about this … this is our background, this is where we come from, the present order of the world has descended from that moment. |
The conversation points to several biases at work that lull us into a state of ignorant bliss highly conducive to Black Swans. There is scientific dogma, which is a kind of confirmation bias in which incoming evidence is fitted to the received models of explanation. Any dissenters presenting alternative interpretations of the evidence are (according to Rogan's guests) ruthlessly clamped down on and stripped of their sources of funding. There is also the issue of political agendas, where the ruling ideology will only accept facts that support the preferred narrative (currently, man as solely responsible for global warming). Finally, there is the sheer existential discomfort that results from having to ponder the fact that asteroid impacts are a regularly occurring phenomenon in deep history. Many of us just do not like being told that the Earth is essentially a sitting duck in space just waiting for the next swarm of asteroids to come our way. Others, in contrast, remain open to consider what the facts are trying to tell us no matter what conclusions they lead us to. A wide gap in expectations has opened up, and this matters, not least in the kind of competitive interaction we will take an interest in later.
MEET THE PREPPERS
Few would be more open to alternative interpretations of the facts than the so‐called ‘preppers’. These are the folks who take the issue of cataclysms very seriously, and who prepare for them with passion. In fact, you could accuse them of having an overactive imagination, of buying into conspiracy theories left and right. There is indeed a fringe element in this movement, with a clear anti‐government stance and a
