Our hunt for aliens has a potentially fatal flaw — we’re the ones searching for them.
That’s a problem because we’re a unique species, and alien-seeking scientists are an even stranger and more specialized bunch. As a result, their all-too human assumptions may get in the way of their alien-listening endeavors. To get around this, the Breakthrough Listen project, a $100-million initiative scouring the cosmos for signals of otherworldly beings as part of the Search for Extraterrestrial Intelligence (SETI), is asking anthropologists to help unmask some of these biases.
“It’s kind of a joke at Breakthrough Listen,” Claire Webb, an anthropology and history of science student at the Massachusetts Institute of Technology, said here on Jan. 8 at the 235th meeting of the American Astronomical Society (AAS) in Honolulu. “They tell me: ‘We’re studying aliens, and you’re studying us.'”
Since 2017, Webb has worked with Breakthrough Listen to examine how SETI researchers think about aliens, produce knowledge, and perhaps inadvertently place anthropocentric assumptions into their work.
She sometimes describes her efforts as “making the familiar strange.”
For instance, your life might seem perfectly ordinary — maybe involving being hunched over at a desk and shuttling electrons around between computers — until examined through an anthropological lens, which points out that this is not exactly a universal state of affairs. At the conference, Webb presented a poster looking at how Breakthrough Listen scientists use artificial intelligence (AI) to sift through large data sets and try to uncover potential technosignatures, or indicators of technology or tool use by alien organisms.
