Resilience, not collapse: What the Easter Island myth gets wrong

--- Quote ---You probably know this story, or a version of it: On Easter Island, the people cut down every tree, perhaps to make fields for agriculture or to erect giant statues to honor their clans. This foolish decision led to a catastrophic collapse, with only a few thousand remaining to witness the first European boats landing on their remote shores in 1722.

But did the demographic collapse at the core of the Easter Island myth really happen? The answer, according to new research by Binghamton University anthropologists Robert DiNapoli and Carl Lipo, is no.
...
Standard statistical methods don’t work when it comes to linking the radiocarbon data to environmental and climate changes, and the population shifts connected with them. To do so would involve estimating a “likelihood function,” which is currently difficult to compute. Approximate Bayesian Computation, however, is a form of statistical modeling that doesn’t require a likelihood function, and thus gives researchers a workaround, DiNapoli explained.

Using this technique, the researchers determined that the island experienced steady population growth from its initial settlement until European contact in 1722. After that date, two models show a possible population plateau, while another two models show possible decline.
