Dutch navigator Willem de Vlamingh, by finding black swans in Western Australia in 1697, showed how risky it is to declare something impossible. I have been thinking anew about the problem of induction recently, and wished to explain and contrast two proposed solutions. The problem of induction is the philosophical issue involved in deciding the place of induction in determining empirical truth. Ergo, any black ravens in the past, through this statement, are evidence that swans are white. The Problem of Induction and Artificial Intelligence by Donald Gillies ... Europe, but when European explorers went to Australia they observed black swans for the first time. Inductive reasoning is the primary methodology of science. While it is easy to prove false, it can never be proven true, no matter how many observations are made. Karl Popper, for instance, regarded the problem of induction as insurmountable, but he argued that science is not in fact based on inductive inferences at all (Popper 1935 [1959]).

Tautologically, information theory propounds that if the probability at which one expects to receive a message is close to one, the information received from the message is close to zero. Our earlier belief is supposed to be arrived at by induction. Induction, making a claim based on a series of observations is generally a risky proposition. We say nowadays that discovery of a black swan in Australia refutes the Europeans’ hypothesis that all swans are white. In the second and more interesting case, we can only draw this conclusion by insisting that the laws of nature will remain the same tomorrow as they have in the past (I am here ignoring the possibility that the sun will be destroyed by some event consistent with current natural laws).

Taleb's thesis is that not only are black swans — new information or events entirely outside our expectations or predictions — more common than we think they are, they're far more influential as well. The "problem" of induction is in regard to whether inductive reasoning leads to knowledge. But as noted above, there are good black swans which positively impact human existence.

Whenever new data arises (whenever a black swan is discovered) their theories have to change accordingly. One of these solutions is Popper’s falsificationism; the other solution is what I believe has been implicitly accepted and taught by other philosophers. Now Professor Davies and most of my class didn't find this terribly interesting or important, I don't think, and most of their critiques seemed to rest on the problem that Raveswans aren't a natural category.
