In the human computation problems described in the previous section, the researchers knew how to solve the problems given sufficient time. That is, Kevin Schawinski could have classified all million galaxies himself, if he had unlimited time. Sometimes, however, researchers encounter problems where the challenge comes not from the scale but from the inherent difficulty of the task itself. In the past, a researcher facing one of these intellectually challenging tasks might have asked colleagues for advice. Now, these problems can also be tackled by creating an open call project. You might have a research problem suitable for an open call if you’ve ever thought: “I don’t know how to solve this problem, but I’m sure that someone else does.”
