Piscine Pursuit, Annihilating Invasives,
and Dory’s Dandy
The media has a way of snowballing information. An anecdote gives way to an estimate that, in the hands of others, turns into an established fact. That’s what happened with a feature we published in May 2016 called “
Breeding Dory.” In addition to following a group of scientists as they attempted to raise blue tangs in captivity, the article commented on the increased demand for clownfish after
Finding Nemo hit theaters.
The anecdote in question came out of an email exchange between Emily Sohn, the author of “Breeding Dory,” and one of her sources and concerned how ornamental fish traders were seeing an increase in demand for clownfish. When Emily asked her source, a marine biologist, to elaborate on this increase, he estimated it at 40 percent. That estimate informed this line of her story: “After Nemo hit the big screen, sales of orange and white striped clownfish rose by as much as 40 percent, according to some estimates.”
But in the years since the piece was published, scientists have debunked this theory of the Nemo effect. So when our news editor contacted Emily to look into new research that dispelled a similar theory for
Finding Dory and blue tangs, she found that not only had the researcher cited her article as an example of the clamor surrounding both of these theories, but that other outlets had widely circulated her 40 percent estimate. That would have been fine if these
other publications hadn’t failed to hedge that number as an estimate. Instead, that number was republished as fact.
When I contacted Emily, the writer of this week’s “
Rumors of Dory’s Demise Were Greatly Exaggerated,” she said that what most surprised her after her feature was published was how other news organizations churn out “aggregate-style content that essentially compiles and repeats sentences from other articles. The risk of doing this is that speculation of unknown origins can quickly become ‘conventional wisdom.’”
What happened in the aftermath of “Breeding Dory” shows us how the media needs to be more careful, more diligent. I’m echoing Emily when I say that we owe it to our readers to operate in that way.
