A large team of scientists with a wide variety of backgrounds has joined together to suggest that a data-driven approach to search for life elsewhere in the universe should replace methods now in use. In their paper posted on the arXiv preprint server, the group explains how a data-driven approach could help prevent human-centered biases from overlooking potential signs of life.
Over the past few decades, scientists have become much more open to the possibility of discovering life in places other than on Earth. And because of that, more work has been done to find life—or at least signs of it. But, as the group on this new effort points out, most such approaches tend to expect that other forms of life will resemble those found on Earth. And that could be blinding scientists to signs of life that might be there but are being missed.
To overcome such a problem, the researchers suggest a more data-driven approach be used. They note that a lot of data have been obtained regarding various parts of the night sky. They also note that the data are in different formats. Some are radio wave graphs, while others describe the attributes of light emitted by a section of the sky, or even a given planet.
